Tides and the Moon
I was recently tasked with examining the relationship between the Earth's moon and the Earth's
tides. I took that to mean literally: how are the tide levels of Earth's bodies of water affected by the
Moon? When approaching this question I want to do so with the scientific method in mind. The
scientific method refers to a body of techniques for investigating phenomena, acquiring new
knowledge, or correcting and integrating previous knowledge (Goldhaber & Nieto, 2010). The
scientific method is a way to ask and answer scientific questions by making observations and doing
experiments. It is also a good tool when we are searching for cause and effect relationships in ...

Spring tides are about the same height whether at New or Full Moon, because the tidal bulge occurs
on both sides of the Earth, the side toward the Moon (or sun) and the side away from the Moon (or
Sun). They will not be equally high because the distance between the Earth and Sun, and the Earth
and Moon both vary and so will their tide producing effectiveness. The highest Spring tides occur
when the Moon is at its closest to the Earth this is called a Perigean Tide (Ninderthana, 2011).
The moon's point of closest approach or perigee is approximately 362,570 kilometers from Earth,
and its apogee, or the farthest point in the moon's elliptical orbit, is approximately 405,410
kilometers from Earth (Image: 1. p. 7). If the lunar perigee occurs when the Moon is between the
Sun and the Earth, it produces unusually high Spring tides. When lunar perigee occurs on the
opposite side from the Earth than where the Sun is located it produces unusually low, Neap Tides
(Image: 2. p. 7). The high, High Tide is called the Proxigean Spring Tide, and it occurs not more
than once every 1.5 years (Ninderthana, 2011).
In the published work by Fergus J. Wood, Tidal Dynamics, Wood stated that, "because of the
gravitational nature of the interaction between the Earth, the Moon, and the water on the Earth, there
is a curious amplification event called 'evection' that occurs when the Moon is at its closest 'perigee'
distance called its 'proxigee'. The Moon draws even closer to the Earth than

The Tide Rises, The Tide Falls
In "The Tide Rises, the Tide Falls" by Henry Wadsworth Longfellow, the poem talks about the
never–ending cycle of life and death and how the world keeps moving on through it all. The theme
is shown through metaphor, repetition, personification, and symbolism. The line "The tide rises, the
tide falls" is a metaphor for the cycle of life and death. It compares the tide rising to a rise in a new
generation. The tide falling is a comparison for their passing away. This metaphor shows our
journey up through life, but everything must fall. It is not a positive comparison, nor is it negative. It
is just a way of life and showing that it goes on, even if your presence in the natural world may fall
apart without a trace. The repetition of these lines

Crimson Tide Review Released in 1995, Crimson Tide tells a dramatic war story of how loyalty
collides with conscience aboard the USS Alabama. Captain Frank Ramsey (Gene Hackman) and his
new XO Lieutenant Commander Ron Hunter (Denzel Washington) are charged with preventing
Russian Rebels from launching missiles at the US and Japan. They struggle to maintain their
position in Russian waters as they wait for orders via an emergency action message (EAM).
Tensions rise as the ship is attacked and damaged. The whole crew is polarized as the captain and
his XO sharply disagree on how to react when a partial EAM is received after a previous command
to launch an attack on Russia's launch complex. Crimson Tide, was directed by Tony Scott and
produced by Don Simpson and Jerry Bruckheimer and distributed by Buena Vista Pictures
Distribution, Inc. The director and crew effectively use music, lighting, varying camera angles, and
symbols with hidden meanings, to build tension and represent each character's approach to keeping
the balance between humanity and unquestioning obedience. The soundtrack for Crimson Tide was
produced by German composer Hans Florian Zimmer. His acoustic ability to blend sounds from
nature, synthesizer, choir, guitar, and philharmonic orchestra, evoke an array of emotions varying
from scene to scene. In the beginning of the movie, Mr. Zimmer composed "Goodbye" for Lt. Ron

Haustrum scobina (Oyster Borer)
The Haustrum scobina (or more commonly Oyster Borer) are green curved sea snail looking
organisms found on the rocky shore. In our data it was most common from the mid to lower littoral
ranges ranging from 40m to 90m. The peak of H. scobina was at 70m from the high tide mark (the
same as C. officinalis), with the width encompassing 20 oyster borers.
The niche (role taken as an organism follows):
The H. scobina pries open barnacle plates then uses its proboscis to feed on the organism inside. It
can also feed on mussels, oysters and other molluscs by drilling through their skulls with its radula.
The largest abiotic factors the H. scobina faces is the wind currents and exposure to air, so it has
developed the following adaptations to help it survive:
The H. scobina has the structural adaptation of a strong muscular foot to open up plated organisms,
this helps it feed in this environment as well as keeping it surfaced while large wind and ocean
currents try and push it along. Another structural adaptation is its tough, waterproof outer shell that
protects it from it's

Analyzing Interspecific Relations Between Species Found On...
When visiting Te Raekaihou Point on the New Zealand Rocky Shore, our intent was to analyse
interspecific relations between species found on the Rocky Shore and to investigate a pattern in the
ecological community. Samples were taken using transect lines and quadrats, and observations were
made both in terms of a site profile, as well as making measurements such as Salinity, pH of the
Water, Air Temperature, Water Temperature and Light Intensity. The two species I have chosen to
investigate the relationship between were the Ornate Limpet (Cellana Ornata) and the Black Nerite
(Nerita Melanotragus). he main abiotic factors were Tidal Movement and the Substrate on the shore.
The community pattern analysed was Zonation. This is shown in the Kite Diagram created from the
class–set of data, where there are distinct bands of species along the intertidal zone. The Rocky
Shore Habitat is tidal, being on the coast of New Zealand, at Te Raekaihou Point, there were several
rock pools, as well as a large amount of bare rock. The intertidal zone and exposure to air in this
zone were important as several species living in this zone rely on the water to avoid desiccation, this
is why crevices and rock pools were a key factor in the zonation and distribution of species on the
Rocky Shore.
Ornate Limpet (Cellana Ornata)
The Ornate Limpet is a grazing shellfish, and can generally be found from the mid to high tide
region, as is seen on the Kite Diagram (Appendix A), there were larger numbers

The Hungry Tide: A Desired Utopia of Political Ecology In The Hungry Tide, Amitav Ghosh
explores the ecosystem of the Sundarbans, varying narration between third person and first person
perspectives, primarily through the main characters Piya, Kanai, and Fokir. The story traces the
transformation of these three main characters from disengaged spectators to invested insiders.
However, each of them perceives the biome of tide country through quite different lenses and their
experiential and educational backgrounds are significantly diverse. Because of the individuated
points of view and differential knowledge and power, conflicts emerge. This essay will interpret the

In order to address the conflict between the rights of local people and the Bengal tiger, a
conservation project was issued in 1973, turning a large proportion of the Sundarbans into a refuge.
It is in this context that the story takes place, and through this context that Ghosh evaluates the
extent to which such a utopian ideal is possible. Among the three main characters, Piya is a Bengali–
American cetologist who travels to the tideland in order to find and research the Irrawaddy and
Orcaella dolphins that are native to the region. Piya was born in Calcutta and moved to Seattle with
her parents when she was one–year–old. Her father believed that, in order to better assimilate into
U.S. culture, the family should sever its ties to India. Therefore, growing up in a family whose
children are not allowed to access their own language, Piya can only speak English. Being the
emblem of the conservation politics that has heavily influenced the Sundarban Islands, Piya tries to
appreciate the country's unique culture and its people, but is impeded by her own morals and the
characteristics which come from being an American citizen. This can be elucidated by Piya's
confrontation with the villagers who kill and burn a tiger alive inside a mud hut in retribution of
their deceased villagers and livestock that were slaughtered by the creature. Although Piya's
attempts to stop this attack are failed, her stance is evident–people are not

Thermodynamics: Intertidal Benthic Cells
The benthic environment has life in, or on, the sand, mud, and rocks. There are two intertidal
benthic zones: rocky intertidal and estuary/salt marsh. The rocky intertidal is a rocky mountainous
which has been eroded by the wave action and weathering. It is composed of a steep slope. There is
an extreme difference between high and low tides. Different from the rocky intertidal is the
estuary/salt marsh this is shallow and has less wave action. Coupled with a shallow slope. The
source of benthic energy is sustained through three methods. The first is benthic microalgae, who
are single celled and are microscopic organisms. They do primary production, it is here that
cyanobacteria, dinoflagellates, and diatoms reside. The second is benthic macroalgae that are the
seaweeds. It has leafy reds, kelps, and sea grasses. The third is sedimentation is the sediment of
particles. Primary production occurs in the surface of the ocean and once they sink to the bottom,
this is primary production, but not directly. ... Show more content on Helpwriting.net ...
The organisms that live on top of the sea are called epifauna and the organisms that live inside the
benthic environment are called infauna. The prokaryotes/bacteria contribute to the recycling of
nutrients. In addition, they transfer DOM up the trophic pyramid. The following consumer is
protozoan bacterivores they eat the bacteria. Another consumer is the harpacticoids, who feed
primarily on ciliates and microalagae. The macro–organism is broken into two categories suspension
(worms) and deposit feeders (bivalves or worms). The top predators are the fish, sea stars, and
crustaceans. They all contribute to the biogeochemical cycling if they are efficient then high
recycling occurs, if there is low efficacy then high burial occurs. Burial removes the matter for

Vertical Zonation and the Rocky Shore
Student Number: 500890847

Vertical Zonation and the Rocky Shore
According to Yonge (1949), "the zoning of both plants and animals within the narrow vertical limits
of a rocky shore is one of the most striking features about shore life." It is noticeable particularly
where sessile organisms (such as barnacles) occur in abundance on the boundaries of their vertical
distribution, as they form a conspicuous line (Boaden & Seed, 1985). The author has also been
particularly impressed by clear zonation patterns of brown algae often to be found on rocky shores.
Precise and universal demarcation of these zones is impossible (Brehaut, 1982), but a
comprehension of the vertical zonation of rocky shores is clearly ... Show more content on

At mid–shore, for example, exposure is 50 percent of the time to air, and 50 percent to water. This
area forms the eulittoral zone, and a greater number of species are found here than in the littoral
fringe. Communities found in this zone must be tolerant of short periods of exposure to air between
the tides, although they almost always require regular submersion or "at least a thorough wetting"
(Tait and Dipper, 1998). Species include barnacles, mussels, and other sessile forms such as oysters
(Boaden & Seed, 1985). The barnacles commonly belong to such genera as Balanus, Chthamalus,
and Tetraclita. There is a strong tendency (Stephenson & Stephenson, 1972) for this zone to be
further divided into two or three subzones. In lower subzones, barnacles may be obliterated or
overshadowed by other sedentary forms; but in the higher eulittoral subzones barnacles are greatest
in concentration, and show dominance. The eulittoral is bounded at the top end by the disappearance
of barnacles in any significant quantity (Stephenson & Stephenson, 1972).
The lowest part of the shore is uncovered at extreme low water spring tide, never at neap tides, and
is known as the sublittoral zone. Where wave action is particularly strong, this zone may not even be
uncovered except when the lowest spring tides coincide with calm weather. As such, this zone is
exposed to the air for very short periods, and for a very small proportion, of time. In many places, it

The Distribution Of The Ornate Limpet
Biology report
Aim of this investigation
The aim of this investigation is to look at the distribution of the ornate limpet, (Cellana Ornata) and
the radiate limpet (Cellana Radians) on the rocky shore. We went to the rocky shore of Sirens rocks
between Island Bay and Owhiro Bay, on Wellington's South Coast. We are studying how our chosen
organisms affect each other's distribution patterns. We sampled in the low tide zone, mid tide zone,
and high tide zone. The rocky shore we explored was 80 metre long, rocky terrain, bare rock
platforms with rock gulley's.
Description of limpets
Limpets have conical shells. The limpets that are situated higher up on the shore tend to have taller
shells than those on the lower shore. The underside of the limpet has a muscular 'foot' on which the
limpet moves around on.
Identification of organisms
Radiate limpets are identified by their flatter shells than the ornate limpet shells. Radiate limpets can
have 20–25 smooth low radial ribs. In the North Island the ribs are more indistinct and maybe
absent, the shell has radial streaks of brown and white. In the South Island the shells are dark grey
with fine radial lines. Ornate limpets are identified by their radiating black bands with a row of
white specks.
Biology of organisms
An ecological niche refers to an organism's way of life – where it lives, its habitat, how it lives there
and its adaptions. The radiate limpet lives in the low tide zone of the rocky platforms whereas the

The Physical Aspects of the Mpenjati Estuary System
A study on the physical aspects of the Mpenjati estuary– beach system.
Roxanne Munsamy
University Of KwaZulu–Natal
Abstract
A study was conducted at the Mpenjati estuary on the 4th of August 2012 to determine the physical
aspects within the estuary beach system. This paper gives an overview of the factors affecting the
slope of the estuary, sediment sizes and the tidal prisms. The beach slope was measured using the
Emery board method and it was found to be characteristic of the KwaZulu–Natal coastline. Wave
energy and sediment transport rates along the beach morphology are interlinked, high energy storms
tend to erode and flatten beaches whilst lower energy waves tend to be responsible for the reverse
process– rebuilding breaches. A ... Show more content on Helpwriting.net ...
The main aim of this study conducted on the Mpenjati estuary was to determine the effects of the
beach processes on temporarily open/closed estuaries, in particular wave action as well as the
transportation of sediment and to understand the influence that they may have on the state of the
estuary mouth. The objective of the study was to determine the elevation of the beach profile or
slope and grain size by using the Emery Board method as well as to analyze the natural stream flow
into the estuary using flow duration analysis with relation to mouth dynamics.
Materials and methods.
The Mpenjati estuary is a temporarily open/closed estuary which is located approximately 165km
Southwest of Durban. The river mouth is generally closed during the winter months and is enclosed
by a sand bar separating the saline rich ocean water from the fresh water river.
On field, the time as well as tide was noted down. The equipment needed was two measuring
poles/sticks with measurements in centimetres written on and a two meter length of rope. The
Emery board method was used and all procedures were followed accordingly. Each group consisted
of 20 members and was then subdivided again into groups of ten. Students took a turn to be a
seaward surveyor and a landward surveyor, a data researcher and a geotechnical engineer. The
respective measurements were taken starting from the baseline as well as the cross–shore data
points.

And for the value of C which is the horizontal translation, by trial and error method, I have found
that by + π12 to the function which translate the function to the left along the x–axis.
And D is the principal axis, as the min. value and max. value has already changed, so the new value
for D would be 12.15+0.82=6.475
Hence we will get a modified function y=5.675sinx2+π12+6.475
Diagram3 Graph of the modified function y=5.675sinx2+π12+6.475 in method4
From diagram 3, we can see that the modified function has passed through 11 data points in total,
which is 3 times more than the old function. So it is obvious a better fit to the data points.
Method 5: Decide what time a good sailor should launch their boat based on the model in method 4
An outgoing tide is a receding tide , i.e. a tide that decreases from it's max height(crest) to its min.
height(trough), from our observations on the graph in method 4 , the max. height of the tide occurs
at 2.6 hours after midnight and 15.2 hours after midnight which is 2:36am and 3:12pm respectively.
However, it's more sensible to launch a boat in day light rather than in the dark, therefore the best
for a good sailor to launch a boat would be 3:12pm. But since the function modeled in part 4 is not a
perfit fit, therefore the perdiction of the best time to launch a boat is a theoretical guess.

The Hungry Tide, By Amitav Ghosh
Nature cannot be separated from humanity. This may seem obvious as humans are a part of the
natural world, but too many times people often overlook this fact of their existence. Most likely this
is a result of movements such as the Industrial Revolution which has brought man from the natural
environment to an artificial environment. In the beginning, and even now, this has been seen as a
luxury and a testimony to the power of mankind. It seems as if man has outsmarted nature.
However, we are only now beginning to see the true effects of this seeming victory, as climate
change becomes a more threatening and inescapable force. In the novel The Hungry Tide, author,
Amitav Ghosh, uses a cross between narration and environmentalism as a ... Show more content on

In this description, the sun and tide become personified in the active voice. This is not true
personification because Ghosh still uses the pronoun "it" to describe both of the natural elements.
However, the use of the active voice creates a sense of personification because it gives a feeling of
action to objects we do not normally think to act. By doing this, the author forces the reader to
acknowledge that all of nature is alive and active in somewhat similar ways as humans. Even the
nature of objects like the sun and a river are alive despite their lack of biology. Their life does not
come from cells but from the movement and patterns of their cycles, like the cycle of the sunrise in
the morning and the sunset in the evening.
The difference between the life of nature and the life of human beings, and other biological creatures
exist in time. Compared to the lifespan of the natural world, humanity's lifespan as a whole is a tiny
speck. Nature existed before humanity and can go on existing even after the end of humanity. In an
article on climate change, written by Chakrabrty, he uses the words "finitude of humanity" to
describe this possibility of nature living on without humans. This possibility is ever increasing as
climate change continues to threaten human's very existence by

Introduction
"'Climate change' refers to any long–term change in Earth's climate, or in the climate of a region or
city. This includes warming, cooling and changes besides temperature." (NASA Oct.2011) Earth is
going through the climate change of global warming. Climate change is causing a big threat that
would cause great catastrophe to the world and this problem will influence everyone around the
world. These changes are caused by the greenhouse gases which are produced when burning fossil
fuels and transportation. When fossil fuels are burned, they generate a fair amount of energy for
people, but at the same time, produce large amounts of pollution that damages our Earth. To slow
down climate change, we need to start making changes and shift our sole energy source from
burning fossil fuels to an alternative renewable energy source. While tidal energy is an interesting
technology and is capable of providing us a carbon–free society, but it can never generate enough
energy to reduce the burning of fossil fuels because of the massive cost for the project and there is
limited places in the world to install the technology.

Tidal energy is converted based on the movements of tides. Tidal power is the result of Earth's
rotation combined with the sun and moon's gravity. The tides come mostly from the Moon's gravity
and a little from the Sun's gravity. So as the Earth rotates, the ocean surface rises and falls.
Compared to nuclear reserves or fossil fuels, the resource of tidal energy will not run out or end
unless the sun and moon does. Usually, there are two high tides and two low tides each day. With all
the water moving up and down, we can capture the kinetic energy from the tides. It works just like
wind turbine except ocean tides turn the blades instead of wind. (Climate Kids,

Our family began traveling to Maine when I was around 10 .It's a gorgeous place but the water is
frigid, and it took a couple of trips before I was willing to go in the water. I was finally inspired to

Brown Barnacle are also known as filter feeders so they feed off of algae and plankton. Brown
Barnacle are not found in the low tide zones for this reason their shells can close off meaning that
they can survive out of water longer by keeping water locked in their shells. Lepsiella Scobina or
oyster borer are a predatory sea snail species. they feed off of barnacle and other prey they are found
in the mid–high tide zones of rocky shores and not low tide. Oyster borer are frequently hidding in
crevices to hide from predators. Oyster borer are not found in high tide but mid–low tides as they
can not close their shells off completely

Competition can be intraspecific meaning between members of the same species or interspecific
meaning members of others species. If a brown barnacle is in a competition between members of its
own species or with a member of another species it will try to not stick its bottom by anything else
so it will be able to get enough food to survive. Brown barnacle has a hard shell so when predators
like the oyster borer come up at high tide and mid tide to kill and eat it, the brown barnacle will try
and fight it off but it does not always win. The brown barnacle feed off of algae that is on the same
rock as them by scooping water and any food into the opening of its shell. The brown barnacle also

Study Of Organisms Living On The Rocky Shore Essay
On Wednesday the 9th of March, Students from Sacred Heart College Travelled by Bus to Siren's
Rock's which lies between Owhiro Bay and Island Bay. At Siren's rocks we had to explore the rocks
and collect data of all the different species we found at the rocky shore. The rocky shore is an
intertidal place where solid rocks predominate. It is useful for the study of Organisms living on the
rocky shore. The rocky shore consists of the low tide, mid tide, high tide and splash zones. We used
quadrats to sample which species was located in these zones and we did this when the tide was low.
Quadrats is a sampling method used to see which organisms are located in certain proportions. The
species I have chosen to talk about in my report today is one type of Limpet and one type of Top
Shell. The common name for the Limpet I found is the Golden/ Radiate Limpet of whose scientific
name is Cellana Radians which was found in the lower intertidal zone. The Cellana Radians is
predated by starfish, whelks and shore birds. The Limpet is an herbivore because it eats Algae and
Angiosperm which both are types of growing plants located within the rocky shore. The common
name for the species of Top shell I found was actually Scorched Monodont whose scientific name is
Diloma (Melagaphia) Aesthiops which is also found in the Lower intertidal name zone. The Diloma
(Melagraphia) Aesthiops is predated by starfish, shore crabs and coastal reef fish. The Diloma

part of the rock face their greatest potential exposure to air? Explain. At day 11 the organisms that
are at the highest part of the rock experience the greatest exposure to air because the tide does not
get as high during neap tides.
8.1 – Briefly describe what you notice about the distribution patterns for each species on the
following days. Do both species settle on the same parts of the rock face? Do their distribution
patterns of the rock face change over time?
Days 1–7:
The species randomly settle throughout the rock. Both species are settled at the bottom and top.
They settle on same parts of the rocks as the other species did. There is more of an abundance of the
Chthamalus than the Semibalanus. On day 28: On day 28 there is a large abundance of both species
however, they have established the area in which they will settle. The Semibalanus have a large
abundance between 0–2 m and scattered abundance above that height. The Chthamalus have a large

Life In A Tide Pool Research Paper
Ocean water is always moving, and gravity from the sun and the moon pulling on the waters of the
ocean causes what's called tides. Each day there are two high tides, when the water moves higher
onto the beach, and two low tides, when the water moves further away from the beach back out
toward the main body of water. A tidepool is a pool of water left behind by the ocean tides. Oysters,
seabirds, blue crabs, and cordgrass can all live in a tidepool. Let's explore the tidepool habitat.
When high tides come up onto the beach, the water brings animals and plants with it. Tide pools are
formed when low tide takes the water back out toward the sea, and some water gets trapped and left
behind. Things like rocks and low spots, like shallow holes, can keep the water from leaving the
beach area. Plants and animals can make a tidepool their home, or habitat. A habitat is the
environment in which plants and animals live.
Plants and animals in a tidepool habitat live in an aquatic habitat, or water environment. Life in a
tide pool is not easy. Although high tide brings into the tide pool more fresh seawater, animals, and
plants, the waves are very powerful. Also, once low tide happens again, the tide pool begins ... Show
Some creatures found in tide pools, such as starfish and anemones, have special suction–cup type of
feet that are sticky and help them to securely attach to solid things such as rocks so they won't get
washed away by the powerful incoming waves. Starfish, also called sea stars, typically have five
arms, but some species of starfish have 10 or even 40 arms! Their colors help them hide from
predators, and they have bony, hard skin to also help protect them. The sticky foot of the sea
anemone has venom–filled tentacles that rise up from it and surround the mouth. If prey, such as
fish, get injected with the venom, the tentacles then guide the prey into the

Descriptive Essay
My family and I were vacationing in Alaska for my graduation trip in the summer of 2014. The
Caines Head Coastal Trail, in Seward Alaska, was designated as one of the top 20 hikes in Alaska so
we could not pass up the opportunity to adventure into the Alaskan wilderness (Best Hiking in
Alaska). The trailhead begins at the entrance of the rainforest. The trail continues along the rocky
shores of Resurrection Bay and then ascends to Fort McGilvray. Although, the first two miles of the
trail was easy, the vivid green colors of the natural forest floor came to life. When we made it to
Tonsina Point (picture 1) the decision was made that my mom and I would continue to the fort,
camp, and hike out in the morning. Meanwhile, my dad and sister would go back to town for a
gourmet dinner. As mom and I continued we kept a quick pace because we were racing against the
clock. The locals warned us to get off the beach before the tide started to come in. We took this
warning seriously because the beach would be 30 feet underwater at high tide.
Now moving along the Costal Trail we walked right along the shore on the jagged slate. Carefully
stepping on one slippery rock after another, our pace slowed. The ever–creeping tide came closer
and at points forced us to wade knee deep through the freezing water. Our adrenalin got us to derby
cove at 6:00 P.M., but we knew it was possibly too late. One rocky point jetting out into the water
was the only thing keeping us from achieving our goal

The Waves Zone And The Mid Tide Zone
As the Cellana denticulata is distributed in the upper lower intertidal zone and the mid tide zone it
must be able to withstand the upper lower intertidal zone and the mid tide zone as the rocky shore
experiences tidal fluctuations (abiotic factor) that occurs in a regular pattern in which the beach has
submerged areas and desiccated areas (the niche of the Cellana denticulata) this is an abiotic factor
that affects their survival. Tidal fluctuations are when the tide (sea) comes in and submerges areas of
the rocky shore while others are exposed. The tide ranges in vertical differences along the rocky
shore; from high tide, mid tide to low tide this is called zonation. These are the tides that fluctuate in
a regular pattern along the rocky shore and this is mainly due to the gravitation pull of the moon.
However the sun also affects the tides but has less gravitational force as the sun is further away from
earth. The gravitational pull of the moon is the main cause for tidal fluctuations as the moon has a
stronger gravitational pull as it is closer to the earth than the sun, hence the main cause for tidal
fluctuations as the gravitational pull from the moon exerted onto earth is greater than the earth.
Because the earth is in constant motion of rotation the earth and the moon become closer in distance
as the earth is not perfectly round and has uneven surfaces. These uneven surfaces or areas of the
earth are closer in distance to the moon and therefore the gravitational pull

Tide Rises, The Tide Falls
The reasoning of why I chose this poem, considering that it falls in the category of all living
organisms. It's that our own selves come with a deadline, but the world we live in keeps revolving.
In my eyes, it signifies that no one person is greater than the other as each one of us are alike. This
poem caught my interest with all images shown from the text. It certainly makes me feel all of what
the author is attempting to visibly demonstrate. This poem displays what occurs in everyday life as
one goes away the world keeps moving, further new forms of life make it back. The Tide Rises, The

In just the title, "The Tide Rises, The Tide Falls" one can tell or draw a grasp of what the poem will
be about. As for my perspective, this signifies that one is washed away or realistically passes away
while another comes to life. It is just a cycle that never has an ending. As for the whole poem, the
meaning is about how death is an enormous factor in the world that our own selves live in. It has an
extensive role as every single one of us going to perish at some point, but there is always someone
new that will replace us when we're gone. It shows how nature is with a non ending cycle, which
keeps our life ways to continue for bounteous years to come. The poem has a nice but also a
mournful meaning to it. Our way in which us life organisms live as death being an immense factor,
having a great deal of a sentimental value. Ultimately, each person only has one life, they decide
what they accomplish with it along with forming the best of it. This is the basic meaning of what the
poem is, how death is a massive factor in our world which we live

Could Sea Waves Be Used To Generate Energy? Essay
Sea waves could be converted into electricity by use of different Outer Continental Shelf energy
apparatuses including terminators, point absorbers, attenuators, and overtopping devices. Using
horizontal axis turbines, ocean currents can also be used to generate electricity. Likewise, sea tides
can be employed to produce electricity by using tidal energy turbines. Temperature differences
between the upper and lower waters of the sea may also be used to generate power through the

II. 2. Terminators Terminators (see figs. 2 and 3) elongate perpendicularly to wave direction and
reflect or capture the energy contained in waves. They are normally nearshore or onshore, with a
few floating editions that may be used offshore in existence. Within the fluctuating water column
terminator, water goes in through some subsurface aperture into a chamber and thus entraps air
overhead. Due to wave activity, trapped water moves up ward and downward like some piston. Such
movement pushes air into an aperture that is linked to a turbine that produces energy. Based on
dimensions and wave parameters, terminators have energy scores of between 500 kW and 2 MW. II.
3. Overtopping gadgets Similar to a dam, overtopping gadgets (see fig. 4) feature basins into which
inward bound waves enter and cause a small upsurge of pressure. After it is released, water streams
back into the sea through gravity. The retreating water releases energy that is utilized to rotate hydro
turbines and to create power. By channeling waves through in–house turbines that later release water
into the ocean, special floating podiums may as well generate electricity. II. 4. Point absorbers Point
absorbers denote floating devices that comprise constituents that shift in relation to each other owing
to wave activity. These gadgets may feature a suspended buoy that is inside a container. To convert

Nature in The Hungry Tide Nature and literature have constantly shared an intimate relationship as
demonstrated in the creations of artists and writers across generations in all societies of the world.
The Hungry Tide by Amitav Ghosh is a novel about individuals of his Motherland and the nation
itself, beautiful, different, and mythical India. The writer exemplifies brilliant nature, individuals,
customs and even issues with tremendous love and respect.The ecological issues turn out to be
increasingly apparent, while the specialists do their best to overlook them. It is not only the
legislature at blame, but the citizens as well. The primary reason is obliviousness. The Hungry Tide,
develops nature by utilizing interlacing legends, experience, myths and history to uncover human
association with the non–human world. It likewise makes an endeavor to discover his cognizant
engagement with the regular world that attracts our thinking to the tragedy of the global
environment.The novel manufactures a noticeable worry about the survival of a balanced
environment like the sundarbans and it also records The situation of the misplaced refugees in their
bountiful surroundings to guarantee their survival.The Hungry Tide steps into the environmental
conflict with a plea for moderation. The Hungry Tide pleas for the acknowledgement and
understanding of the predicament of the poor by environmentalists and of animals and nature by
human rights groups. Ghosh accomplishes this by utilizing

(Refer to Appendix 5 for the graph of the function:L=417 sin⁡
[2π/365 (t–81)]+744). As a regression
analysis the function itself was used to find daylight hours. The hours were then compared to the
original data points. This comparison resulted in a percentage error being recorded. (Refer to
Appendix 5 for the results of the function and percentage errors). The highest percentage error
recorded was 7.35% on February 1st 2011. This error could be because February has 29 days in a
leap year but 2011 data was used. The error could also occur because only 24 data points were used,
if more data points were used a more precise graph would have been generated leaving less space
for error.
Question 1e:
Simple deriving and calculus was used to verify that the equation L=417 sin⁡
[2π/365 (t–81)]+744 for

Human Activities And Its Effects On The Ocean Tides Essay
Estuaries
An estuary is a partially enclosed body of water formed where the freshwater from the land mixes
and meets with saltwater from the sea. As a result, the salinity and water level among various other
factors, is dependent on the ocean tides.
80% of the world's cities are situated near an estuary. For its abundance in resources are crucial to to
the longevity of the cities. It is recognized globally as one of the most threatened ecologies in the
world. Human activities such as agriculture, waste water processing, land clearance, introduction of
exotic species have rapidly increased the erosion rate of rivers, and have redirected river flows both
into and within estuaries. This in turn leads to its accelerated aging process. Sediments from rivers
upstream are rapidly surging into the estuary at a rate more than the tide could erode away. Estuaries
that exist without human activities collect a net sediment layer of 1 millimetre per year. This is
directly juxtaposed to the poorly maintained estuaries disrupted by human activities, gaining a
staggering net sediment layer of 20 millimetres per year. Eventually this causes many estuarine
ecologies to decay and render them incapable of supporting life.
The estuarine ecology is a spawning pool for many coastal organisms. Both visiting and local
species raise their young within the estuarine habitat. The habitat supports an enormous range of
species, such as shellfish, crabs, marble worms, algae, mangroves, cockles and

Because of the Earth's large capacity of water and relationship with gravity, tidal waves through
extreme tidal storms are created. The Moon heavily influences the movement of Earth's tides by
shifting and relating land features, using its gravitational pull to change the height of the tides, and
also affecting the speed of the Moon's revolution. To start, the Earth's aquatic tides are the constant
rise and fall of bodies of water every day (Jacobs 9). Gravity, provided by the Moon and some parts
of the Sun, helps create the ocean's tides (Jacobs 10). It is also often caused by the winds forcefully

Land tides are pieces of ground or land that are slowly shifted up and down twice by the
gravitational force between the Sun and Moon ("The"). Because of important use of mainly sunlight,
land tides occur most near the Equator and not often in the poles. These tides happen in four cycles:
the lunar diurnal, lunar semidiurnal, solar diurnal, and solar semidiurnal ("Tides"). Diurnal tides last
24 hours while semidiurnal tides only last 12 hours. During a land tide, the center of the Earth to the
outer crust takes time to deform under the Moon and Sun ("The"). The deformation takes toll on
geological processes and volcanic eruptions ("Tides"). To include, scientists found that volcanic
eruptions and tides have a relationship because of the magma flowing in volcanoes. Geologists use
specific instruments like: seismometers, tiltmeters, and strainmeters to measure slow shifts. Results
from these tools are placed on a graph to view the various movements of Earth. In 1978, Spahr
Webb, former M.I.T student, measured with two thirty–six feet tiltmeters and found a tidal tilt in
Earth's surface that was .01 of an inch (Wylie

Analysis Of The Prince Of Tides
In Pat Conroy's The Prince of Tides, Tom's relationship with his family is based on the shortcomings
of his parents as well as the bond between the Wingo children. In the passage above, Tom
reminisces on his past with Savannah and Luke while also commenting on his lack of purpose and
inability to help in the present. Tom's portrayal of his strong familial connection to his siblings
demonstrates both the underlying power of safety in Tom's life and the harsh difficulty of the real
world. Overall, Tom develops feelings of hopelessness and an inability to cope with his loss which
is brought out by Conroy's use of imagery, tone, and point of view. Conroy begins by describing
Tom's solace when being with Savannah and Luke under the water, bringing attention to the ethereal
feel of their connection and the stability Tom finds in their involvement in his life. Conroy uses
imagery to demonstrate the river as a place of freedom and the tightness of the Wingo children's
bond. It is described as a "green river, full–tided and still as linen" (Conroy 453), which is
comfortable and full of life. Tom's whole experience is like the freedom of being on air, with "the
end of the floating dock" (453), that they "floated together" (454), and they "would rise together"
(454) in the river. This floating imagery is complemented by the emphasis on the sun, with "sun–
sweet water" and an "explosion of sunlight and breath". This explanation of their experience brings
light to two things. Tom feels

The Importance Of Mangroves In Australia
Mangroves are trees and shrubs that can be found along coastal intertidal zones in tropical and
subtropical areas near the equator due to their inability to survive in low temperatures. Mangroves
are found not only in australia but on coastlines all over the world and are distributed over 100
countries in the tropical and sub–tropical regions of the world. Australia contains the third largest
area of mangroves in the world after Indonesia and Brazil, totalling around 11,500 km2 representing
approximately 6.4% of the world's total mangrove area (Appendix A) (Mangrovewatch.com, 2017).
There are 73 different types of mangrove species in the world. 39 of these mangrove species dwell
in Australia. The intertidal zone or littoral zone, is the area that is exposed at low tide but is
submerged by seawater during high tide. Mangroves survive in salt water on sheltered muddy
shores, because they have adapted to the harsh abiotic conditions in order to survive in their area.
Mangroves also provide a habitat for marine organisms such as fish, crabs and yabbies. Furthermore
they provide a habitat for many land animals such as birds, pythons, lizards and crocodiles. How
mangroves contribute to the functioning of intertidal ecosystems will be discussed on this report.
Mangroves have a very important role in their ecosystem. Their niche includes protecting and
providing for many organisms. Mangroves are considered main producers in their complex food
system (Appendix B). "The food chain

Nudgee Beach Lab Report
Abstract
The aim of this experiment is to test the changes in and effects o abiotic and biotic factors along a
transect line form low tide to high tide in the mangroves at Nudgee Beach. The hypothesis is that at
low tide the soil texture would be a brown clay with a pH of 9–10, however; at high tide the soil
would be light brown sand with a ph of –8–9. The purpose of this report is to analyze whether the
hypothesis true. The results found match with the hypothesis. At low tide the pH was 8 ½ , whereas
at high tide the pH was 8. At each tide, the air temperatures were similar, except for the low tide,
where the temperature was 17.5°C. The conclusion made was that because mangroves grow better

As the water level inside the chamber raises and lowers, the difference air pressure turns a low
resistance turbine, generating power. The turbine spins in one direction no matter if the air is pulling
or pushing. The collectors have been design in this manner to obtain the maximum output of power
out of the machines. Most of these wave collectors, also known as oscillating water columns are still
experimental. This device is regarded as the world most advanced wave–to–electricity generators.
An oscillating water column in Norway is being tested and can produce 500 kilowatts of electricity.
A "Salter Duck", is another invention that has been developed to produce power from waves. This
machine is basically two large pontoons hinged together at their ends. The bobbing action of the
pontoons gives the mechanical advantage to drive the internal generator. This was the first invention
to receive wide spread use to make ocean generated power. The United States Coast Guard has been
using many of these to power generating tools for their navigation lights and audio transmitters.
Another type of energy the ocean has to offer is her tides. Generators used to harness power from
ocean tides are the cheapest to build. This is for the shear fact that most of the tide power stations
are connected to land. Due to logistics it is a lot easier to build objects closer to land than in the
middle of the ocean. These power stations can

Cabrillo believed to have discovered when he landed at Mission Bay. Unfortunately Cabrillo was
not impressed with the bay because it was not deep enough to accommodate his ships, so he left it.
In 1852 the United States Army Corps attempted to prevent water from flowing into the San Diego
River, this resulted in "False Bay" and the waters surrounding Paradise Point to become an estuary.
This only last two years as two dams were eventually built on the North and South side to constrain
the river. Then in the late 1800's some recreational development that included hunting and fishing
facilities were built but later destroyed by flooding. Finally in 1902 George Hall, the city
horticulture commissions recommended that the 4600 acres of water be developed into an aquatic
park. This is where Mr. Skirball, the movie producer and developer of Paradise Point entered the

Wind and Waves
WIND:
 Winds are caused by differences in air pressure.
 They move from areas of high pressure to low pressure.
 Differences in air pressure are caused by unequal heating of the atmosphere.
 Cool air has higher air pressure so it flows underneath the warm, less dense air.
 Winds that blow over short distances and are caused by unequal heating of Earth's surface within
a small area.
Waves
 Waves start in the open ocean
 The size of a wave depends on the strength of the wind, the length of time that it blows, and the
distance over which it blows
 Waves move energy, not water. The water in a wave does not actually move forward, just the

 The cold, saltier water sinks and starts moving back towards the equator along the bottom of the
ocean.
 When the water reaches the equator, it warms and rises again.
 Deep currents flow slowly. They may take as long as 1,000 years to flow from pole to equator and
back again.
TIDES:
 Tides are the daily rise and fall of Earth's waters on its coastlines
 When water on the coast reaches its highest point it is high tide.
 When water on the coast reaches its lowest point it is low tide.
 Unlike surface waves, tides are regular and do not depend on wind. If not wind, then what causes
tides?
 Tides are caused by the interaction between the Earth, the moon, and the sun.
 The gravity exerted on Earth's oceans by the moon and the sun cause the water to move from one
side of the planet to the other side.
 The moon is much closer to the Earth than the sun, so it exerts a greater gravitational effect on the
tides.
 There are two high tides and two low tides about every 25 hours.
 That means every six or so hours you have a high tide and then a bit
 more than six hours later you have a low tide.

 Changes in the positions of Earth, the moon, and the sun affect the

are in the exact position in the sun's gravitational field to keep us in orbit and keep life ongoing on
our planet. Gravity is a downward force on any body of mass, the larger the mass of the body, the
stronger the gravitational force. On earth the force is 9.8 N/Kg (Newton's per Kilogram) roughly,
depending on where you are on earth.
Gravitation
The original idea of gravity was discovered by Sir Isaac Newton (Jacob 1999). It is ... Show more

In fact, both orbit about their common center of mass, which is within the Earth but not at its center.
This rotation causes an upward centrifugal force on the oceans, which is proportional to the
rotational speed and the distance from the center of mass. This force is greater on the far side then
the near side" (Gravity and Tides 2000)
When you add this to the moons gravitational force, they equal. This causes both sides of the ocean
to bulge as illustrated in the diagram above causing 2 high tides, about 12h and 25 minutes apart.
Relatively the same idea applies to the effects of the Sun on Earth, though the centrifugal force on
the near side of earth is downward, not upward. As it turns out, the force of the sun is about half the
force of the moon. We get the high spring tides when the Earth, Sun and Moon are in a straight line
and their forces are combined. After 7 days when they are at right angles to each other they cancel
each others forces giving the low neep tides. A very important factor about tides that is not included
in the above, is the height of the ocean floor. Different heights can cause funneling of the tidal flow,
heaping the tides up in shallow water and causing even more complex effects where flows meet.
Conclusion
Gravity is an essential to life. It is also one of the four key physical forces which are, Gravity,
Electromagnitivity, Strong Nuclear Force and Weak Nuclear Force (Physics for a Modern World
1986). It

Amitav Ghosh the Hungry Tide and the Interesting Narrative...
Both The Hungry Tide and The Interesting Narrative Of Olaudah Equiano are tales of sociological
hardships combined with a life bound to the sea. The ocean plays a significant role in the text
offering disempowerment to some whilst empowering others. In The Interesting Narrative the slave
trade was in full swing and a capitalist attitude heavily dominates the text, whilst in The Hungry
Tide capitalism plays a smaller role and the humanitarian backdrop of the story is a more central
theme. In this essay I will draw into focus the various ways in which the ocean is represented as
empowering and disempowering to the lives of characters looking at them as they develop through
the text and contrasting their empowerment against that of others. ... Show more content on

To attempt to leave the island would likely result in death and the most fearful disempowerment
possible. Hywel Dix argues that 'with no money, power, or political influence, they are simply
treated as objects to be shunted from one location to another.'[9] Dix is here arguing that the weak
become weaker at the hands of a greater force, which is exactly what happens to the settlers. The
ocean is therefore seen as disempowering at the hands of the powerful government forces. This use
of the ocean as a way of the strong disempowering the weak is also seen in The Interesting
Narrative. In the same way the ocean is used to imprison the settler's, the Africans find themselves
similarly imprisoned by it on board their ship. Equiano makes a direct reference to his ship as being
like a prison; 'I was ready to curse the tide that bore us, the gale that wafted my prison.'[10] The
ocean is much like the police controlled perimeter that keeps them captive with the looming threat
of death for those who attempt to escape. Gilbert C. Klingel supports this notion of the ocean as
being like that of a prison; 'it is a prison without bars or cells, the only walls are the lines of
gleaming surf.'[11] Much like the settlers, Equiano is powerless to resist and is therefore kept
captive by the ocean. In exactly the same way

Waves : Wave, Tides, And Currents
Waves, Tides, and Currents
Waves, tides and currents are three types of natural phenomena that occur on water and whilst they
are similar in nature, they are not the same thing. While all three are related to bodies of water, they
differ based on their causes, intensity and frequency among other factors [1]. Another common
misconception is that while these phenomena are known to drive the sea, the ocean itself is not
responsible for the generation of waves, tides and currents. Waves for example are influenced by the
action of wind on the surface of the ocean while currents are influenced by the heat from the sun on
the equator and cooler poles. Tides on the other hand are caused by gravitational forces from the
moon and sun. All three contain some form of moving and potential energy and slight changes can
lead to much larger downstream effects that affect nearby communities and recreational users.
Waves
Waves are defined as the movement of water that occurs on the surface of water bodies like oceans,
seas, lakes and rivers. While no two waves are identical, they share common traits like having a
measurable height which is defined as the distance from its crest to its trough.
What influences waves?
They are usually created by winds which transfer energy to the water as they blow over. This results
in the production of small water movements known as ripples [1]. These ripples can subsequently
grow in size, length and speed to form what we know as waves. These waves are
