Marine biomes make up the largest percentage of aquatic biomes on Earth and involve a medium to high percentage of salt in the water. They include oceans, coral reefs, and estuaries. Coral reefs are usually found in shallow, warm waters and are important for controlling carbon dioxide levels and protecting coasts from strong currents. Estuaries involve both freshwater and salt water, protecting water quality while serving as centers of coastal communities. Marine biomes contribute substantially to global oxygen production and carbon dioxide absorption.
A presentation for Marine Biology about Estuaries which includes its origin, classifications, types, physical characteristics, ecosystems, and human impact. Examples of estuaries are also included in this presentation.
Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes and ponds, rivers, streams and springs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content. This module explains the characteristics of aquatic ecosystems-freshwater ones.

Biological oceanography is a major scientific discipline dealing with all aspects of marine life under different zones of the oceanic environments. The interest to study biology by humans started as early as fourth century BC when Aristotle described about 180 species of marine animals. The geographical knowledge of oceans got improved after several great sea expeditions conducted by the people from 15th to 16th centuries. Through Ocean explorations people conducted detailed underwater surveys and mapped the ocean floors with respect to their physical features, chemistry and biological conditions.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. BIOMES
• a biome is a major, geographically extensive
ecosystem, structurally characterized by its
dominant life forms
• most of the oceans are considered part of a single
biome, although areas with particularly unusual or
unique physical characteristics or inhabitants may be
considered as separate biomes
3. MARINE BIOMES
• marine biomes make up the largest percentage of
aquatic biomes on earth. unlike freshwater
biomes, these biomes involve a medium to high
percentage of salt in the water
• marine biomes generally have salt concentrations
that average 3%.
4. • marine algae and photosynthetic bacteria supply a
substantial portion of the world’s oxygen and consume
huge amounts of atmospheric carbon dioxide.
5. 2 TYPES OF WATER BIOMES
• FRESHWATER
• rivers and streams
• lakes and ponds
• SALTWATER
• ocean
• estuaries
• seashores (tidal areas)
6. FRESHWATER BIOMES
• freshwater contains little or
no salt, so it has a low
salinity.
flowing freshwater = rivers and
streams
still freshwater = lakes and
ponds
7. flowing freshwater
• streams
• the faster a stream flows
the greater the amount of
dissolved oxygen in it.
faster water flows = oxygen
9. flowing freshwater
• rivers
• water moves slower in a river
and debris settles on the
bottom.
• because of this, rivers tend to
have more nutrients and less
dissolved oxygen.
nutrients and
oxygen
10. FRESHWATER
• ponds
• small, shallow bodies of water
• sunlight penetrates all the way to the
bottom
• most completely filled with plant
material
• very high amount of nutrients
11. FRESHWATER
• lakes
• larger and deeper than ponds
• plant growth is limited to the
shoreline
• sunlight does not penetrate to the
bottom= no plants after a certain
depth!
14. SALTWATER
• Estuaries (wetlands)
• area where a river meets an ocean
• mix of salt and freshwater
• located near coastlines, border land
• extremely fertile
• nutrient levels are higher than both
salt and freshwater
16. SALTWATER
• seashores
• tides have a huge influence on life
here
• intertidal zone- portion of the
shoreline that is covered with
water at high tide and exposed to
the air at low tide.
17. • Intertidal Zone
• can be sandy or rocky
• small fish, clams, crabs, other
mussels are trapped in the tidal
pools during low tide
19. 2 MAIN LIFE ZONES
1. photic zone: surface of water
• phytoplankton and water plants that
use photosynthesis (sunlight
penetrates)
2. aphotic zone: no light/little light
• light levels too low to support
photosynthesis (no sunlight penetrates)
21. MARINE BIOMES
plankton are microscopic algae,
plants, and other organisms that
float on the surface of water
biomes.
They need
sunlight to
survive.
22. WHY IS PLANKTON SO
IMPORTANT?
• Gross Primary Productivity –
Rate at which an ecosystem’s
producers capture and store
chemical energy.
• Net Primary Productivity –
Rate at which all plants in
ecosystems produce useful
chemical energy.
• Ultraplankton is responsible
They are the first step in many aquatic
for 70% of primary
food chains
productivity near the ocean

30. CORAL REEFS
• ARE W
IDELY DISTRIBUTED IN WARM SHALLOW WATERS
• DOMINATED BY STRUCTURE OF CORAL ITSELF
• FORMED BY DIVERSE GROUP OF CNIDARIANS THAT SECRETE
HARD EXTERNAL SKELETONS MADE OF CALCIUM
CARBONATE
• CERATES A SUBSTRATE UPON WHICH OTHER CORALS,
SPONGES, ALGAE GROW
• VERY DIVERSE ASSORTMENT OF VERTEBRATES AND INVERTEBRATES
• VERY PRODUCTIVE
• CURRENTS AND WAVES CONSTANTLY RENEW NUTRIENTS
• LIGHT PENETRATES TO OCEAN FLOOR ALLOWING
PHOTOSYNTHESIS
31. CORAL REEFS
• coral reefs are usually found in shallow,
warm waters. they are found along
continents, islands, and atolls. coral reefs
are made of algae and tissues of animal
polyp. these areas tend to be poor in
nutrients, however the coral gets its
nutrients from the algae
32. IMPORTANCE OF CORAL
REEFS
• coral are very important in controlling how much
carbon dioxide is in the ocean water. without
coral, the amount of carbon dioxide in the water
would rise dramatically and that would affect all
living things on earth.
• in addition, coral reefs are very important because
they protect coasts from strong currents
and waves by slowing down the water before
it gets to the shore. that is why they are called
barrier reefs. they provide a barrier between the
ocean and the shore.
33. • coral reefs are the “rainforests” of
the ocean. reefs are ecologically
important ecosystems and have a high
biodiversity that serves as a storage
bank of rich genetic resources
38. NOTES
• BIOME : LARGE ECOSYSTEM WITH DOMINANT
LIFE FORMS
• MARINE BIOMES MAKE UP THE LARGEST
PERCENTAGE OF AQUATIC BIOMES ON EARTH
(MEDIUM/HIGH LEVELS OF SALT)
• MARINE BIOMES INCLUDE OCEANS, CORAL

DRAMATIC FORMS OF WEATHER OCCURS OVER THE
OCEANS(EX: TROPICAL CYCLONES )
OCEAN CURRENTS GREATLY AFFECT THE EARTH'S CLIMATE
BY TRANSFERRING WARM OR COLD AIR AND PRECIPITATION
TO COASTAL REGIONS, WHERE THEY MAY BE CARRIED
INLAND BY WINDS.
THE ANTARCTIC CIRCUMPOLAR CURRENT ENCIRCLES THAT
CONTINENT, INFLUENCING THE AREA'S CLIMATE AND
CONNECTING CURRENTS IN SEVERAL OCEANS.
AROUND HALF OF ALL CARBON DIOXIDE PRODUCED BY
HUMANS SINCE THE INDUSTRIAL REVOLUTION HAS
DISSOLVED INTO THE WORLD'S OCEANS
41. • CORAL REEFS ARE USUALLY FOUND IN SHALLOW, WARM
WATERS
• CORAL ARE VERY IMPORTANT IN CONTROLLING HOW
MUCH CARBON DIOXIDE IS IN THE OCEAN WATER.
• CORAL REEFS PROTECT COASTS FROM STRONG
CURRENTS AND WAVES BY SLOWING DOWN THE WATER
BEFORE IT GETS TO THE SHORE
• CORAL REEFS HAVE A HIGH BIODIVERSITY THAT SERVES
AS A STORAGE BANK OF RICH GENETIC RESOURCES
• ESTUARIES INVOLVE BOTH FRESHWATER AND SALT
WATER. THEY PROTECT WATER QUALITY BY FILTERING
OUT DIRT AND POLLUTION AND ARE OFTEN THE
CENTERS OF COASTAL COMMUNITIES
