Issues of coastal area in kerala
In kerala most of peoples are depends on fishing. Generally fishermen have no financial security in kerala. In about 46% of marine fishermen households have ownership on some means of production and 45% of fishermen are in debts. They are mainly in the clutches of the local leaders and being exploited by the middlemen. He is mainly dependent on the daily fish catches that he does for which the price of it is very less.. His family mainly depends on him.About 0.7 million fisherfolk was as labourers.Medical care,sanitation,and other amenities of the fishing villages lacks importance from the government side.Most fishermen’s children have little hope of education or of social or financial advancement.If they are sick there is little hope of proper medical attention.Fishermen are one of most backward people who have to educated and subsequent increase in social and economic conditions should be primary goal.
Flood
Floods occur when heavy rain or snowmelt causes a river's water levels to exceed its channel capacity, overflowing onto the flood plain. There are three main types of flooding: coastal from ocean waters, river from excessive water in river channels, and ground water from saturated soil. Individual precautions include having an emergency radio, staying off flooded roads, and avoiding electrical hazards, while after a flood it is important to check for structural damage, boil water, and reduce future flood risk.

Floods in India
This document provides an introduction to floods, including their definition, types, causes, and impacts. It discusses areal floods, flash floods, river floods, coastal floods, urban floods, and catastrophic floods. The major causes of floods are described as heavy rainfall, siltation of river beds, blockages in drains, landslides, and dam/reservoir construction. The document then focuses on floods in India, outlining major flood-prone areas and state-level vulnerability trends. Several significant flood events across India are highlighted, including the 1987 Bihar floods, 2005 Gujarat floods, 2005 Maharashtra floods, 2012 Assam floods, 2013 Uttarakhand floods, and 2014 Jammu & Kashmir
Painting the water picture
This document discusses challenges related to water resource management in Kenya, including deforestation, soil erosion, water scarcity, pollution, and conflicts over water usage. It notes issues such as the lack of water during dry seasons, encroachment into wetlands, inappropriate water utilization, and poor management of springs. The goal of integrated water resource management (IWRM) planning is outlined as changing lives by addressing priority water problems through a basin planning approach that takes all water-related activities and developments into account to achieve sustainable use. Opportunities for IWRM include managing watershed resources like agriculture land, wetlands, and forests.
Climate Change Ryan India
1) Many parts of India have experienced extensive flooding due to heavy and extended monsoon rains, affecting millions of people.
2) Flooding has numerous causes from local drainage issues to larger scale factors like climate change altering monsoon patterns, landslides, and improper city planning that reduces natural drainage.
3) Floods have significant economic, infrastructure, and health impacts through damage to property, disruption to transportation, loss of farmland, disease outbreak, and loss of life. Countermeasures are needed at individual, community, and national levels.
Flooding on the somerset levels
Winter 2013/14 saw prolonged heavy rain and flooding on the Somerset Levels. The Levels are a 650 square kilometer area of low-lying coastal plain and wetland in central Somerset that is prone to flooding. The flooding affected over 600 homes, blocked major roads, and prevented farmers from grazing animals or working their farms. Responses included deploying rescue boats, sending in Royal Marines for flood relief, and promising over £30 million for repairs. A 20-year flood action plan was also drafted.

Mozambique Floods 2000
Mozambique experienced catastrophic flooding in 2000 due to continuous heavy rainfall over 5 weeks that was exacerbated by a hurricane, totaling over 1,163mm of rain compared to the average of 177mm. The floods killed many thousands of people, left 1 million homeless, and caused huge economic losses. Disease and malnutrition spread due to a lack of clean water, food, and medical supplies after infrastructure like bridges and roads were destroyed. Flood risk is managed through limited monitoring, but the country cannot afford major prevention schemes due to poverty. International aid helped rescue and supply refugee camps, though conditions remained poor.
flood and drought management
Floods occur when there is heavy rainfall and overflowing rivers, exceeding normal water levels. This can be caused by urban drainage issues, inadequate river capacity, storm surges, melting snow or ice. Floods impact the economy, environment and lives of people and animals. Management strategies include better flood warning systems, modifying structures to withstand flooding, protecting wetlands, restoring natural river courses, and improving water storage and soil conditions.
Hoover dam and the negative effects on environment
The document summarizes some of the negative environmental impacts of the Hoover Dam on the Colorado River ecosystem. It discusses how the dam led to lowering of the riverbed downstream, releasing of greenhouse gases from the reservoir, and destruction of local ecosystems and fish species. Several endangered fish native to the Colorado River were negatively affected by changes in water flow and temperature from the dam. While the dam provided benefits, its construction significantly altered the natural environment of the Colorado River basin.
Conflict over water resources: Colorado River
The Colorado River Basin spans seven U.S. states and Mexico, with competing demands for water from agriculture, cities, and industry. During the 20th century, the river was dammed and diverted extensively through major infrastructure projects to supply water to over 25 million people. However, long-term drought and overallocation of water rights have led to conflicts as the river now rarely reaches the sea. Managing this vital resource equitably between multiple stakeholders remains an ongoing challenge.
Impact of river sand mining on environment by Dulanjali M. Wijethilake
The document discusses the environmental impacts of river sand mining. It finds that sand mining can have long-lasting physical impacts by degrading river channels over decades of extraction. This destroys aquatic and riparian habitats through changes in channel morphology. Specifically, it leads to increased sediment loads and turbidity, along with altering ecologically important features in the river bed. Sand mining also modifies riparian zones and lowers groundwater levels. In Sri Lanka, unregulated sand mining has severely impacted several major rivers like Kalu Ganga and Kelani Ganga. The document calls for limiting mining to floodplains and following guidelines to reduce environmental damage.
International journal of science technology
Sand is an important mineral for our society in protecting the
environment, where this practice of sand and soil mining is becoming an
environmental issue as the demand for sand increases in industry and construction.
Mining and its associated activities can be responsible for considerable
environmental damage. In this article we are discussing about the direct and indirect
impacts due to soil and sand mining to the environment in Indian regions. Pollution
of the water is evident by the colouration of water which in most of the rivers and
streams in the mining area varies from brownish to reddish orange. Low pH (between 2-
3), high electrical conductivity, high concentration of ions of sulphate and iron and toxic
heavy metals, low dissolved oxygen (DO) and high BOD are some of the physicochemical
and biological parameters which characterize the degradation of water quality.
Contamination of Acid Mine Drainage (AMD) originating from mines and spoils,
leaching of heavy metals, organic enrichment and silting by sand particles are major
causes of degradation of water quality.
Dynamic planet revision 2016
This document provides guidance and questions for an exam on dynamic planet systems. It outlines that students should answer questions 1-4, 6, and 7, focusing on topics like restless earth, climate change, impacts on biospheres and rainforests, water systems, river processes and pressures, and threats facing oceans. Questions include explaining why some volcanoes/earthquakes have greater impacts, primary and secondary effects of volcanic eruptions, reasons climate change predictions are difficult, managing tensions between development and conservation, and disagreements over ocean resource management.
Sand Minning
Sand mining can be done through open pits, dredging river beds, or beaches. It is used to extract sand for construction and manufacturing, as well as minerals like titanium. However, sand mining risks damaging habitat, altering river flows, and increasing turbidity. It can degrade instream and riparian environments by removing vegetation, disturbing river beds and banks, and lowering water tables. Proper siting and monitoring of mining is needed to reduce environmental impacts.
Dynamic planet revision 2015 qus
The document discusses several topics related to plate tectonics and volcanoes:
- Convection currents in the mantle cause plates to move apart, allowing magma to rise and form shield volcanoes. When plates collide, oceanic crust is subducted under continental crust.
- At destructive plate boundaries where subduction occurs, volcanoes form as the melted oceanic crust rises through cracks in the overlying continental crust. These volcanoes are steep and cone-shaped.
- The effects of climate change on oceans and coral reefs include coral bleaching from increased temperatures, rising sea levels submerging coastal ecosystems, and more frequent storms damaging fragile corals. This impacts habitats and food chains.

Flood & Kosi
The document discusses floods, their causes, effects, and management. It notes that floods are among the most common and destructive natural hazards. The main causes of flooding include prolonged rainfall, snowmelt, volcanic eruptions, storms, dam failures, and development in floodplains. Floods can damage infrastructure and agriculture, spread disease, and cause loss of life. Management strategies aim to modify floods, susceptibility, or loss burden through structural measures like dams or non-structural measures like warning systems and zoning. India's major flood-prone states are Bihar, Uttar Pradesh, and Assam. The devastating 2008 Kosi flood in Bihar displaced millions and caused widespread damage costing over $500 million.
Dam failure
The document discusses the failure of the St. Francis Dam in 1928 near Los Angeles, California. It provides background on the dam's design and construction. On March 12, 1928, the dam catastrophically failed, releasing a flood wave that killed an estimated 450 people and destroyed over 1,000 homes and buildings. The failure was likely due to cracks and leaks that were dismissed by the dam's designer. The document recommends lessons for disaster management, including early warning systems and emergency preparedness.

This document provides instructions for a sea star dissection lab where students are tasked with labeling the external and internal structures of a sea star using letter identifiers on diagrams. The external structures include the aboral and oral sides as well as full anatomy diagrams. Internal structures cover the digestive system, reproductive system, and water vascular system.
Coasts
There are two main types of coasts: erosional and depositional. Erosional coasts experience removal of material from land attacks like erosion and sea attacks like storms. Depositional coasts experience addition of material, forming features like beaches, barrier islands, coral reefs, and wetlands. Coral reefs can be fringing, barrier, or atoll reefs depending on their location relative to land.
Population growth notes
A population grows through natality or birth when conditions are favorable. When a population of plankton grows rapidly it is known as a bloom. Population growth stops when conditions become less favorable and resources become limited. Resources like food, nutrients, shelter, and living space are limiting factors. When limiting resources are used up, the population reaches its carrying capacity, which is the largest sustainable population size given available resources.

This document provides an overview of several lower invertebrate phyla, including porifera, cnidaria, annelida, and echinodermata. It describes key characteristics of each phylum such as radial symmetry in cnidaria, and discusses important classes within echinodermata including sea stars, brittlestars, sea cucumbers, and sea urchins. Examples are given of feeding behaviors in young sea stars and coral destruction caused by crown-of-thorn starfish outbreaks on some reefs.
Ocean circulation
The oceans play a key role in regulating Earth's climate through ocean circulation. Warm surface currents, such as the Gulf Stream, transport heat from the tropics towards the poles. Cold, deep currents then move water from the polar regions back towards the equator, completing the ocean conveyor belt which influences weather patterns and temperatures worldwide.
Coastal Communities
Salt marsh communities are found in protected coastal areas dominated by salt-tolerant grasses. They provide important habitat for many species of fish, birds, and invertebrates. Salt marshes act as natural buffers against flooding and filter pollutants from water. However, they face threats from development, ditching, overharvesting, and other human impacts. Mud flats adjacent to salt marshes provide habitat for diverse invertebrate communities and feeding grounds for other species. Seagrass beds in shallow coastal waters create structured habitat and nurseries while improving water quality and moderating currents. However, they are threatened by boat damage, declining water quality from runoff, and rising sea levels. Rocky intertidal
12 lis histnformation
Long Island Sound was formed after the last ice age as the glaciers retreated northward. The glaciers carved deep basins and deposited sediment, leaving behind moraines at the Ronkonkoma Moraine and Harbor Hill Moraine. As streams eroded the landscape, they deposited outwash that formed the foundations of Long Island and Connecticut, bounded by sills that kept the ocean at bay for 8,000 years until sea levels rose approximately 25 meters below present levels.
Pressure density notes
The document discusses thermoclines, haloclines, and pycnoclines in seawater, which are layers in the ocean where temperature, salinity, and density rapidly change with depth. A thermocline is a layer where temperature quickly drops with increasing depth, while a halocline and pycnocline refer to layers where salinity and density increase rapidly with depth as pressure increases underwater. These three factors are interrelated and influence each other as depth from the ocean surface increases.

The document summarizes two kingdoms - Mollusca and Arthropoda. Mollusca includes three classes: Gastropods (snails and nudibranchs), Cephalopods (squid and octopus), and Bivalves (clams, mussels and scallops). Arthropoda includes two subphyla: Chelicerata (sea spiders and horseshoe crabs) and Crustacea (lobsters, crabs, shrimp, etc.). It provides examples of different organisms in each class or subphylum and notes some of their key characteristics like shells, tentacles, blood composition, and mating behaviors. Videos and references are also included for further information.
Marine worms
This document describes the main types of marine worms, which are divided into 6 phyla: Platyhelminthes (flatworms), Nemertea (ribbonworms), Nematoda (roundworms), Chaetagnatha (arrow worms), Pogonophora (deep sea tubeworms), and Annelida (segmented worms). It provides details on the characteristics of flatworms and segmented worms, noting that segmented worms have a more advanced body plan with organ systems and abilities that the other worm phyla lack. Examples of lifestyle and feeding strategies are also given for the Annelida.
Chemo vsphyoto
Chemosynthesis and photosynthesis are two types of synthesis that produce energy and organic compounds. Chemosynthesis uses hydrogen sulfide as an energy source along with oxygen and carbon dioxide to produce glucose, sulfur, and water. Photosynthesis uses sunlight as an energy source to produce glucose and oxygen from carbon dioxide and water. Both processes produce organic compounds and release byproducts but differ in their use of an energy source, with chemosynthesis using chemical energy and photosynthesis using solar energy.

7. oceanography of an estuary
1) A salt wedge occurs in estuaries where freshwater from rivers meets denser saltwater from the ocean, causing the freshwater to ride up over the saltwater like a wedge. 2) The position of the salt wedge changes with the tides, extending further upstream during flood tides and retreating during ebb tides. 3) Estuaries have muddier bottoms than rivers or oceans due to their slower currents, which allow suspended sediments from rivers to sink to the bottom.

2. It also discusses short term changes to sea levels from the 1953 storm surge, which caused major flooding and loss of life in eastern England. Wind and low pressure raised sea levels over 2 meters.
3. The final section examines tourism and recreation on the Dorset coast of England, noting its economic importance but also environmental impacts, and the management strategies employed to mitigate conflicts between different user groups.
Ocean deprivation
The document discusses several issues affecting coral reefs and ocean health, including coral bleaching caused by rising ocean temperatures from global warming, pollution from land-based activities, and overfishing. Coral bleaching occurs when coral release symbiotic algae due to stress, causing them to appear white. Global warming increases ocean temperatures and UV radiation, leading to more frequent bleaching events which could cause coral to go extinct within decades. The document calls for actions like green energy use, conservation, and educating others to help address these problems.
All about coasts
The document discusses several key topics regarding coastal processes and geomorphology:
1) Coasts are important interfaces between land and sea that are hazardous due to erosion and flooding. They also provide economic value through activities like tourism.
2) Coasts are open systems with inputs of energy, sediments, and processes like erosion and deposition that create landforms. They have outputs like deposited material onshore.
3) Sediment cells define discrete lengths of coastline where sediment movement is self-contained through longshore drift. These inform shoreline management plans.

Holderness Towns
1) The coastal town of Hornsea suffers from erosion of weak boulder clay and loss of beach due to longshore sediment drift (LSD). This led to complaints and the construction of sea walls and groynes to build the beach back up as a defense.
2) The sea defenses at Hornsea have starved the nearby area of Mappleton of sand, causing its beaches to wash away from LSD. Two groynes and boulder revetments were constructed here for £2 million, reducing LSD and allowing more deposition.
3) Erosion at Great Cowden has been very rapid at 1-2 meters per year. Properties and farms are at risk from rotational slumping of saturated b
UNIT 05 Marine-Pollution-PPT.pptx
Marine pollution comes from a variety of sources including land-based runoff, oil spills, sewage, heavy metals, and plastics. There are five main types of pollution inputs: direct discharge, runoff, ship pollution, atmospheric deposition, and deep sea mining. Ship pollution includes oil spills and cargo residues while atmospheric pollution includes dust and plastic debris. Deep sea mining disturbs habitats and causes plumes of sediment. Human impacts like eutrophication, acidification, plastic debris, and other toxins threaten marine life. Noise pollution from ships also affects animals, and mitigation requires education and pollution reduction efforts.

Marine pollution
Marine pollution comes from many sources including land-based activities, oil spills, sewage, mining, and shipping. Pollution enters the oceans directly through waste discharges, rivers carrying runoff, and atmospheric deposition. This pollution has negative impacts like toxic chemicals, hypoxia, invasive species, harm to wildlife from entanglement and ingestion of plastic debris, and acidification affecting shells and corals. Preventing marine pollution requires better waste management, regulation of mining and shipping, and reduction of nutrient runoff from agriculture and developed areas.
WATER POLLUTION AND MARINE POLLUTION
Pollution is the introduction of contaminants into the environment that cause harm. Pollutants can be classified as degradable, slowly degradable, or non-degradable. Marine pollution affects ocean life through pollution inputs like direct discharge, runoff, atmospheric deposition, and shipping. Overfishing has depleted fish stocks worldwide due to technological advances enabling overexploitation, with impacts like reduced catches and disruption of marine ecosystems. Solutions include pollution prevention, responsible waste disposal, and sustainable fishing practices.
Seawater
1) Seawater is composed of about 95% water and 5% other elements like sodium and chloride which make up salt. Most of the world's oceans are saline due to these dissolved elements.
2) Ocean currents circulate heat and transfer it between regions, influencing the climate near coasts. The Coriolis effect, caused by the Earth's rotation, causes currents and winds to deflect right in the northern hemisphere and left in the southern hemisphere.
3) Waves are caused by wind, tidal changes, or seismic activity. Breakers occur when waves interact with the seafloor in shallow water, and can be spilling, plunging, or surging depending on the seafloor slope

Hurricanes
Hurricanes form over warm ocean waters between 15 and 200 latitude from the equator when low pressure systems allow warm, humid air to rise and condense. They have a circular structure with counterclockwise spinning winds in the Northern Hemisphere that can be hundreds of miles wide. Hurricanes strengthen over warm ocean waters but weaken when making landfall or interacting with strong upper level winds or cooler waters. They can cause extensive wind damage, flooding from heavy rains, and storm surges that become especially destructive during high tides.
History of Ocean Adventures
This document provides a brief history of notable figures and expeditions that advanced ocean exploration from the 1500s to present day. It describes Portuguese explorer Ferdinand Magellan's leadership of the first voyage to circumnavigate the globe in the 1500s. In the 1700s, Benjamin Franklin mapped the Gulf Stream current. Charles Darwin in the early 1800s described how coral reefs form and introduced the theory of natural selection. The multi-year Challenger Expedition in the late 1800s conducted the first truly oceanographic research cruise. More recent pioneers include Jacques Cousteau who developed modern SCUBA gear and Sylvia Earle who is a renowned marine biologist and conservationist.
Impacts of Temperature and Salinity on Marine Animals
Marine animals are either ectothermic or endothermic, with ectothermic animals like fish having body temperatures dependent on their environment while endothermic animals like mammals and birds can regulate their internal temperatures. All marine animals also must regulate salt levels in their bodies through osmoregulation as temperature and salinity of water can impact animals' physiology and survival.
Plankton PowerPoint
Plankton are tiny organisms that drift or float in the waters of seas, lakes, and rivers. They can be either autotrophs, which produce their own food through photosynthesis (phytoplankton like diatoms and dinoflagellates), or heterotrophs, which consume other organisms for food (zooplankton like tiny crustaceans). Phytoplankton are the base of the oceanic food web and are found in the photic zone where there is enough sunlight for photosynthesis. Some phytoplankton can bloom rapidly and be dangerous. Plankton play an important role in marine ecosystems.
Introduction to biological oceanography notes
This document provides an introduction to key concepts in biological oceanography, including evolution, causes of evolution, and evidence of evolution. It defines evolution as change over time that occurs between species through processes like mutation, genetic drift, gene flow, natural selection, and non-random mating. The document also discusses concepts like overproduction, competition, genetic variation, adaptation, natural selection, speciation, classification, and the criteria used to place organisms into kingdoms.
Marine flowering plants
This document summarizes three groups of marine flowering plants: seagrasses, mangroves, and salt marsh grasses. Seagrasses grow in coastal waters and reproduce both sexually and asexually. Mangroves are woody trees found in tropical and subtropical intertidal zones that reproduce sexually. Salt marsh grasses are found along coasts and reproduce sexually and asexually. All three play an important role as nursery habitats for young marine organisms.
Marine algae
This document provides information about marine algae. It describes the different parts of an algae's thallus including the holdfast, blade, and stipe. It notes that algae can have air bladders to assist with buoyancy. It states that algae are autotrophs that belong to the kingdom Protista or Plantae. There are three main types of algae - green algae, red algae, and brown algae - which differ in their pigments, habitats, and examples. It compares key differences between algae and land plants such as their access to water, support structures, anchoring mechanisms, and reproductive organs.
Waves notes
This document discusses different types of waves, including their causes, characteristics, and behaviors. It defines key wave terminology like crest, trough, wavelength, and period. Wave size is determined by wind strength, duration, and fetch. Deep water waves travel in orbits while shallow water waves feel the bottom and change shape as they reach shore. Breakers come in spilling, plunging, and surging types. Longshore currents move sand along beaches, while rip currents pull water back out to sea. Tsunamis and rogue waves present unique wave hazards.
Fisheries notes
This document summarizes key concepts regarding fisheries management. It defines important terms like fish stocks, exclusive economic zone (EEZ), and mechanisms for harvesting fish. It discusses challenges like bycatch, overfishing, and factors contributing to declining fish populations. Strategies for conservation are outlined, such as gear restrictions, catch limits, and protecting essential fish habitat. The document also reviews agencies and laws involved in fisheries management, such as the Magnuson-Stevens Act and its goals of preventing overfishing while achieving sustainable yields.
Light in the ocean
Most life in the oceans depends on sunlight that autotrophs are able to capture through pigments to photosynthesize and produce food. Different pigments absorb different wavelengths of light, allowing autotrophs to live at varying depths where certain wavelengths penetrate deepest. The rate of photosynthesis must exceed the rate of respiration for phytoplankton to survive, setting a compensation depth above which they can thrive. Coastal waters often have higher turbidity than the open ocean due to sediment and inputs that cloud the water and limit sunlight penetration.
Some equipment used by chemical oceanographers
This document describes several pieces of equipment used by chemical oceanographers to sample and measure various water parameters. It discusses Niskin and Nansen bottles, rosettes, thermometers, hydrometers, refractometers, CTDs, Secchi disks, DO meters, SONAR, and side scan SONAR, and provides brief explanations of how each tool is used.
Composition of seawater
The document summarizes the chemical composition of seawater. It states that seawater is mostly water, but also contains all naturally occurring elements on Earth. The main ions found in seawater are 55% chloride, 31% sodium, 8% sulfate, 4% magnesium, and 1% each of calcium and potassium. These ratios remain relatively constant in oceans around the world according to the law of constant proportions. Exceptions can occur where rivers meet the sea since river water contains more calcium. Salt enters the oceans through weathering that carries eroded rocks and minerals into rivers and seas, and also through underwater volcanic vents. Salt is removed through sea spray, sediment deposits that bind minerals, and biological activity of marine life.
Salinity notes
Salinity refers to the concentration of dissolved ions in water, measured in parts per thousand (‰). Average ocean salinity is 35‰ but it varies depending on evaporation, precipitation, and water sources. Salinity is higher in enclosed seas like the Red Sea (40‰) and Mediterranean Sea (38‰) due to limited freshwater input and high evaporation. It is lower in semi-enclosed seas connected to oceans by narrow straits, like the Black Sea (18‰) and Baltic Sea (8‰), which receive more freshwater from rivers. Temperature, pressure, and density can also impact ocean salinity.
Properties of seawater
Water is a polar molecule with slightly positively and negatively charged ends, allowing it to form hydrogen bonds between molecules. This polarity gives water properties of adhesion, sticking to other substances, and cohesion, sticking to other water molecules. Water has relatively low viscosity and density compared to other liquids, with density highest at 4°C and lower in seawater due to salt content. Its solid form, ice, floats due to having a less dense crystalline structure. Water also has a high specific heat capacity, requiring a lot of energy to change its temperature, which allows oceans to act as a heat buffer for the planet.
12 plate tectonics notes
The document discusses plate tectonics and describes how convection currents in the asthenosphere cause tectonic plates to move horizontally at the surface. There are three types of plate boundaries: divergent boundaries where plates move apart and new seafloor is created, convergent boundaries where plates move together and seafloor is destroyed forming trenches and volcanic islands, and transform boundaries where plates slide past each other forming faults. Examples given are the San Andreas fault and the Ring of Fire around the Pacific plate.
9 zonation in the ocean
The document describes different zones of the ocean based on depth.
The Neritic Zone extends from the shoreline to depths of less than 200 meters over the continental shelf. The Oceanic Zone is the area beyond 200 meters depth and further offshore. The Photic Zone, also known as the Euphotic Zone, extends from the surface to a depth of around 200 meters where sunlight is available for photosynthesis. Below the Photic Zone are the Disphotic Zone from 200-1000 meters with low light, and the Aphotic Zone below 1000 meters with no light.
Sea turtles
There are 8 species of sea turtles that visit areas like Long Island, including the Kemp's Ridley turtle, which is the most endangered with only 400-500 individuals remaining today from a population of 42,000 in 1947. Sea turtles have a three-chambered heart, scales, and lay eggs on land that incubate for around 2 months before hatchlings head to the water. They face numerous threats including humans, predators, habitat loss, and getting caught in fishing nets or ingesting plastic waste which has led to all species being endangered or threatened.
Whales
Whales evolved from land mammals and are related to horses and sheep. They have adaptations like blubber for insulation and temperature regulation, blowholes for breathing, and streamlined bodies. Whales communicate using echolocation and songs, have excellent hearing, and can slow their heart rates while diving. There are two main types of whales: toothed whales that hunt for food and baleen whales that filter feed krill. Whaling nearly wiped out many whale species until laws like the Marine Mammal Protection Act and International Whaling Commission were passed to regulate and protect whales.
Fish morphology
This document discusses the diversity of body shapes and tail fin morphologies in fish and how these adaptations help fish survive in their environments. It describes the main body shapes as fusiform for fast open water swimmers, compressiform for quick bursts of speed, and depressiform for bottom-dwelling fish. It also outlines different tail fin shapes including homocercal forms that are rounded, truncate, forked, or lunate and the heterocercal tail of sharks, and explains how each tail type relates to the fish's swimming ability, speed, maneuverability and environment.
Meet the arthropoda
This document provides an overview of arthropods, which are segmented invertebrates with jointed appendages and an external skeleton. It describes their anatomy, including a chitinous exoskeleton, jointed limbs, segmented bodies, and open circulatory and nervous systems. Arthropods reproduce through external fertilization and development of planktonic larvae. The phylum includes two subphyla: chelicerates like sea spiders and horseshoe crabs, and crustaceans such as lobsters, crabs, shrimp, and barnacles. Arthropods are mostly benthic or epifaunal and found worldwide, representing the largest number of species on Earth.
