The Deep Sea - Smithsonian Ocean
Oceanographers divide the majority of the ocean midwater into five broad zones. The very deepest depth of the ocean is roughly 2,000 meters deeper than Mount Everest is tall—36,070 feet deep (10,994 m)! Each zone has a different mix of species adapted to its specific light level, pressure, temperature, and community.
Deep sea - Wikipedia
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] The deep sea is considered the least ...
Deep-sea Corals - Smithsonian Ocean
Scientists have discovered single polyps as small as a grain of rice, tree-like coral colonies that tower as tall as 10 m (35 ft), and massive coral reefs that stretch for 40 km (25 mi). But the ocean is a vast realm. There may be even bigger deep-sea corals out there still to be discovered.

Deep-sea biodiversity and ecosystems - UNEP
2007年7月21日 · Deep-sea biodiversity and ecosystems responds to key questions, including: where do we find vulnerable deep sea and high sea ecosystems, what are the goods and services they provide, and how are they affected or threatened by existing or emerging human activities and climate change.
Rolling in the Deep: Climate Change and Deep Sea Ecosystems
2020年7月29日 · Through deep ocean mixing (mixing of waters of different temperatures and densities), the deep sea helps drive ocean currents. The deep sea also absorbs heat and atmospheric CO2. In this way, the deep sea acts as a buffer from the effects of climate change.
Deep-Sea Life and Habitats - Deep Sea Conservation Coalition
The deep sea is the largest habitat on Earth. Despite the low temperatures, extreme ambient pressures, absence of sunlight and low resource availability, it supports a rich abundance of life in an array of unique ecosystems.
Deep Sea Biology - Dive & Discover
The deep-sea is defined as the part of the ocean below 200 meters depth. This environment Is considered extremely harsh with temperatures of below 5 degrees Celsius, extreme pressure (2,000 meters equals about 200 times the atmospheric pressure at sea level), and no sunlight.
