  2. Oceanic zone - Wikipedia

    en.wikipedia.org/wiki/Oceanic_zone

    e. The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone. It is the region of open sea beyond the edge ...

  3. Pelagic zone - Wikipedia

    en.wikipedia.org/wiki/Pelagic_zone

    The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. The oceanic zone is the deep open ocean beyond the continental shelf, which contrasts with the inshore waters near the coast, such as in estuaries or on the continental shelf. Waters ...

  4. Marine ecosystem - Wikipedia

    en.wikipedia.org/wiki/Marine_ecosystem

    The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides.

  5. Pelagic fish - Wikipedia

    en.wikipedia.org/wiki/Pelagic_fish

    Oceanic fish inhabit the oceanic zone, which is the deep open water which lies beyond the continental shelves. Oceanic fish (also called open ocean or offshore fish) live in the waters that are not above the continental shelf. Oceanic fish can be contrasted with coastal fish, who do live above the continental shelf. However, the two types are ...

  6. Mesopelagic zone - Wikipedia

    en.wikipedia.org/wiki/Mesopelagic_zone

    The mesopelagic zone has some unique acoustic features. The Sound Fixing and Ranging (SOFAR) channel, where sound travels the slowest due to salinity and temperature variations, is located at the base of the mesopelagic zone at about 600–1,200m. [6] It is a wave-guided zone where sound waves refract within the layer and propagate long ...

  7. Ocean stratification - Wikipedia

    en.wikipedia.org/wiki/Ocean_stratification

    Ocean stratification. Ocean stratification is the natural separation of an ocean's water into horizontal layers by density, which is generally stable because warm water floats on top of cold water, and heating is mostly from the sun, which reinforces that arrangement. Stratification is reduced by wind-forced mechanical mixing, but reinforced by ...

  8. Marine habitat - Wikipedia

    en.wikipedia.org/wiki/Marine_habitat

    A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. [ 1 ] The marine environment supports many kinds of these habitats.

  9. Marine food web - Wikipedia

    en.wikipedia.org/wiki/Marine_food_web

    A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton. The second trophic level (primary consumers) is occupied by zooplankton which feed off the phytoplankton. Higher order consumers complete the web.
