"The creation was a mathematical diagram drawn in parallel lines," T. H. White said a propos the bestiary he translated. "Things did not only have a moral they often had physical counterparts in other strata. There was a horse in the land and a sea-horse in the sea. For that matter there was probably a Pegasus in heaven". [3]
The epipelagic zone (0–200 metres (0–656 ft) deep) is the area where light penetrates the water and photosynthesis occurs. This is also known as the photic zone. Because this typically extends only a few hundred meters below the water, the deep sea, about 90% of the ocean volume, is in darkness.
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 m (660 ft) or the point of transition from continental shelves to continental slopes. [1] [2] Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure. [3]
Brine pools are created through three primary methods: brine rejection below sea ice, dissolution of salts into bottom water through salt tectonics, and geothermal heating of brine at tectonic boundaries and hot spots. Brine rejection: When sea water freezes, salts do not fit into the crystalline structure of ice, so the salts are expelled. The ...
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.
In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include necessary adaptation to colder temperature, food scarcity, reduced predation pressure and ...
The Biogeography of Deep-Water Chemosynthetic Ecosystems is a field project of the Census of Marine Life programme (CoML). The main aim of ChEss is to determine the biogeography of deep-water chemosynthetic ecosystems at a global scale and to understand the processes driving these ecosystems.
Pandalus borealis is one of the hardy species initially chosen to be kept in the Abyss Box Deep sea zones. The Abyss Box is a vessel containing 16 litres (3.5 imp gal; 4.2 US gal) of water at the very high pressure of 18 megapascals to simulate the natural underwater environment of bathyal fauna living at about 1,800 metres (5,900 ft) below the surface.
