What is a community in oceanography?
Community: comprised of the many populations of organisms that interact at a particular location. Largest community (Deep Ocean) is the most sparsely populated.

What is the source of energy for some deep sea communities?
Most of the sulfur comes from the Earth’s interior; a small portion (less than 15 percent) is produced by chemical reaction of the sulfate (SO4) present in the sea water. Thus, the energy source that sustains this deep-ocean ecosystem is not sunlight but rather the energy from chemical reaction (chemosynthesis).
What are the features of coastal erosion?
Features of coastal erosion
- Cliffs usually form where there is soft rock such as limestone and chalk .
- Wave erosion is strongest where large waves break against the base of the cliff.
- A wave-cut notch is formed when the base of the cliff is eroded by hydraulic action, corrosion and corrasion.
- Continual erosion causes the notch to become larger.
What is a coastal cell?
A coastal cell (or littoral cell or sediment cell) is a coastal compartment that contains a closed cycle of sedimentation including sources, transport paths, and sinks.
What is a coastal littoral cell?
A littoral cell is a coastal compartment that contains a complete cycle of sedimentation including sources, transport paths, and sinks. The boundary between cells is delineated by a distinct change in the longshore transport rate of sediment.
What is a littoral system?
The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore. In coastal environments, the littoral zone extends from the high water mark, which is rarely inundated, to shoreline areas that are permanently submerged.
Are all coastlines eroding?
All coastlines are affected by storms and other natural events that cause erosion; the combination of storm surge at high tide with additional effects from strong waves—conditions commonly associated with landfalling tropical storms—creates the most damaging conditions.
What is littoral habitat?
The littoral zone is usually where you will find the majority of aquatic plants since they need sunlight to grow. The littoral zone is also important habitat for fish, shorebirds and aquatic invertebrates because the plants give them refuge from predators and there is abundant food available.
What is the difference between littoral and Limnetic?
The topmost zone near the shore of a lake or pond is the littoral zone. The near-surface open water surrounded by the littoral zone is the limnetic zone. The limnetic zone is well-lighted (like the littoral zone) and is dominated by plankton, both phytoplankton and zooplankton.
