The deepest part of the South China Sea
Zhongsha Great Atoll is the largest atoll in the South China Sea islands, with a length of about 140 km and a width of about 55 km, extending from north to south west, slightly oval. The atolls are all submerged by seawater, and the depth is generally 9-26 metres.
According to Bi Hua, a professor at Hainan Normal University's School of Geography and Tourism, the eastern side of the Great Atoll is a deep and large crustal fault zone, with the landshell and oceanic crust coming into contact at a steep slope of 51C-58C and falling to -4000m. The waters between the twin reefs in the southern part of the Great Atoll and the Spratly Islands are the deepest in the South China Sea (-5559 m), and the heat flow, Bug gravity and magnetic forces are abnormally high and may be related to land mass drift; The west side is xisha, the middle sand trough, the depth of 2000-3000 meters;
