  2. Marine snow - Wikipedia

    en.wikipedia.org/wiki/Marine_snow

    In the deep ocean, marine snow (also known as "ocean dandruff") is a continuous shower of mostly organic detritus falling from the upper layers of the water column. It is a significant means of exporting energy from the light -rich photic zone to the aphotic zone below, which is referred to as the biological pump .

  3. Deep-sea community - Wikipedia

    en.wikipedia.org/wiki/Deep-sea_community

    For the deep-sea ecosystem, the death of a whale is the most important event. A dead whale can bring hundreds of tons of organic matter to the bottom. Whale fall community progresses through three stages: [32] Mobile scavenger stage: Big and mobile deep-sea animals arrive at the site almost immediately after whales fall on the bottom.

  4. Deep sea - Wikipedia

    en.wikipedia.org/wiki/Deep_sea

    Marine snow is organic material that has fallen from upper waters into the deep sea. [ 7 ] In 1960, the bathyscaphe Trieste descended to the bottom of the Mariana Trench near Guam , at 10,911 m (35,797 ft; 6.780 mi), the deepest known spot in any ocean.

  5. Hydrothermal vent - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_vent

    Previously, benthic oceanographers assumed that vent organisms were dependent on marine snow, as deep-sea organisms are. This would leave them dependent on plant life and thus the sun. Some hydrothermal vent organisms do consume this "rain", but with only such a system, life forms would be sparse.

  6. Mesopelagic zone - Wikipedia

    en.wikipedia.org/wiki/Mesopelagic_zone

    It often forms as deep mixed layers at the depth of the thermocline. [5] The mode water in the mesopelagic has residency times on decadal or century scales. [ 5 ] The longer overturning times contrast with the daily and shorter scales that a variety of animals move vertically through the zone and sinking of various debris.

  7. Snow - Wikipedia

    en.wikipedia.org/wiki/Snow

    Snow clouds usually occur in the context of larger weather systems, the most important of which is the low-pressure area, which typically incorporate warm and cold fronts as part of their circulation. Two additional and locally productive sources of snow are lake-effect (also sea-effect) storms and elevation effects, especially in mountains.

  8. Pachystomias - Wikipedia

    en.wikipedia.org/wiki/Pachystomias

    Pachystomias is one of three deep-sea fish that can produce red light bioluminescence, along with Aristostomias, Chirostomias, and Malacosteus.In addition to producing blue light via postorbital photophores, Pachystomias also possess suborbital and preorbital cephalic photophores that are capable of producing far-red bioluminescence, with wavelength emissions of over 650 nm.

  9. Deepsea - Wikipedia

    en.wikipedia.org/wiki/Deepsea

    Deepsea, deep-sea, or deep sea may refer to: the deep sea, the lowest layer of the ocean; Deepsea ASA, a subsidiary of Odfjell Drilling; Deep Sea 3D, an IMAX film;
