Ocean acidification is particularly harmful to deep sea corals because they are made of aragonite, an easily soluble carbonate, and because they are particularly slow growing and will take years to recover. [33] Deep sea trawling is also harming the biodiversity by destroying deep sea habitats which can take years to form. [34]
Deep ocean water has a temperature between −2 °C (28 °F) and 5 °C (41 °F) in all parts of the globe. [14] The temperature gradient over the water depth is related to the way the surface water mixes with deeper water or does not mix (a lack of mixing is called ocean stratification). This depends on the temperature: in the tropics the warm ...
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches.The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions.
The ocean covers 70 percent of our Earth. However, nearly 95 percent its waters remain unexplored and unseen by human eyes, according to the National Ocean Service .
It is the region of open sea beyond the edge of the continental shelf and includes 65% of the ocean's completely open water. The oceanic zone has a wide array of undersea terrain, including trenches that are often deeper than Mount Everest is tall, as well as deep-sea volcanoes and basins. While it is often difficult for life to sustain itself ...
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions.It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
The bathymetry of the ocean was poorly known prior to the Challenger expedition of 1872–1876, [12] which took 492 soundings of the deep ocean. [13] At station #225, the expedition discovered Challenger Deep , [ 14 ] now known to be the southern end of the Mariana Trench .
Climate change is making our oceans change color, new research finds. Jack Guy. July 12, 2023 at 12:42 PM. ... For example, a deep blue sea will have very little life in it, whereas a green color ...
