Local mean sea level ... If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 slightly over 30 cm (1 ...
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 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 deepest point of the trench is more than 2 km (1.2 mi) farther from sea level than the peak of Mount Everest. [a] At the bottom of the trench, the water column above exerts a pressure of 1,086 bar (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%.
Scientists discovered "dark oxygen" produced by deep-sea polymetallic nodules deep below sea level, redefining our understanding of ocean and early Earth life. 4,000 Meters Below Sea Level ...
Sea of Galilee water levels (January 2004 – February 2012) The water level is monitored and regulated. There are three levels at which the alarm is rung: The upper red line, 208.9 m (685 ft) below sea level (BSL), where facilities on the shore start being flooded. The lower red line, 213.2 m (699 ft) BSL, where pumping should stop.
In South Florida, sea levels have already risen several inches since the start of the century and could be around six feet higher by 2100. But another factor could be making those sunny day floods ...
Over geologic time sea level has fluctuated by more than 300 metres, possibly more than 400 metres. The main reasons for sea level fluctuations in the last 15 million years are the Antarctic ice sheet and Antarctic post-glacial rebound during warm periods. The current sea level is about 130 metres higher than the historical minimum.
