abyssal zone, intertidal zone, nertic zone, oceanic zone
abyssal zone- the deepest part of the ocean 2000-6000 meters
benthos:the floor and fauna found benthic zone densityon the bottom ,or in the bottom sediments, of a sea, lake, or other body of water.
Hadal zone (the dark and deep part)--
ecological zone: along the deep ocean floor that is between the bathyal had zone.
The Hadal Zone is the deepest and does include the Trenches
The Hadal Zone is the deepest and does include the Trenches
intertidal zone:the foreshore/seashore somtimes reffed to as the littoral
mixed zone:referring to the loasal unit of the bushveld complex where severl inclusions of the host rocks.

ocean food chains:
A food chain is a sequence of organisms in which each is food for the next member in the sequence. The surface of the sea swarms with billions of microscopic plants, called diatoms. With other plants such as seaweed, diatoms form the first link in most marine food chains. All subsequent links in the food chain are consumers, or the animals.

ocean food web
Marine food web for the Arctic
example ::
Phytoplankton generate organic carbon through photosynthetic reactions.
Phytoplankton are eaten by the zooplankton, who are in turn eaten by fish, on up to large marine mammals. Organic carbon that settles to the sea floor is usually consumed by marine organisms there.
oceanic zone:
The oceanic zone begins in the area off shore where the water measures 200 meters (656 feet) deep or deeper. It is the region of open sea beyond the edge of the continental shelf and includes 65% of the ocean’s completely open water
plankton:
The collection of small or microscopic organisms, including algae and protozoans, that float or drift in great numbers in fresh or salt water, especially at or near the surface, and serve as food for fish and other larger organisms.
phytoplankton:
Some phytoplankton are bacteria, some are protists, and most are single-celled plants
Illustrations of types of phytoplankton.
photic zone:
the surface layer of the ocean that recieves sunlight
pelagic zone:
Any water in a sea or lake that is not close to the bottom or near to the shore can be said to be in the pelagic zone.
Pelagic life decreases with increasing depth. It is affected by light intensity, pressure, temperature, salinity, the supply of dissolved oxygen and nutrients, and the submarine topography. In deep water, the pelagic zone is sometimes called the open-ocean zone
salinity
How are large animals affected by salinity? Whales, sharks and porpoise.
The measure of the salt content in the ocean water is explained via salinity. The average salinity of ocean water is 35 parts per 1,000 grams of water. The salt affects what types of marine life live in which particular habitat, and it also prevents the oceans from freezing; salinity fluctuation can also affect the less salt-tolerant marine life and in some cases cause organisms to move to outlying areas such as the mouth of rivers. Climate, weather, currents and seasons can all have an affect on salinity.

How does the ocean become salty?:
dissolving action of rains and streams which transported their mineral washings to the sea. Some of the ocean's salts have been dissolved from rocks and sediments below its floor. Other sources of salts include the solid and gaseous materials that escaped from the Earth's crust through volcanic vents or that originated in the atmosphere.
What factors affect salinity of the ocean? Please include Images of these factors.::
It is affected by such factors as melting of ice, inflow of river water, evaporation, rain, snowfall, wind, wave motion, and ocean currents that cause horizontal and vertical mixing of the saltwater. rain melting ice caps
How is salinity of the ocean measured?
Starting in 2008, the Aquarius mission will measure global SSS with unprecedented resolution. The science instruments will include a set of three radiometers that are sensitive to salinity (1.413 GHz; L-band) and a scatterometer that corrects for the ocean's surface roughness. The spacecraft will be contributed by Argentina's Comisión Nacional de Actividades Espaciales (CONAE). http://science.nasa.gov/earth-science/oceanography/physical-ocean/salinity/
surface zone.:
The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists. With the light come heat. This heat is responsible for the wide range of temperatures that occur in this zone.
thermocline:
The thermocline is the transition layer between the mixed layer at the surface and the deep water layer. The definitions of these layers are based on temperature.
transition zone ^^^^ thermo cline and transitional layer is the same :)
