Weddell Sea Bottom Water : ウィキペディア英語版 | Weddell Sea Bottom Water Weddell Sea Bottom Water (WSBW) is a subset of Antarctic Bottom Water (AABW) that is at a temperature of -0.7 °C or colder. It consists of a higher salinity branch and a lower salinity branch. It originates in the Weddell Sea and closely follows the sea floor as it flows out into the rest of the world's oceans. It is created mainly due to the high surface winds blowing off the Antarctic continent which helps cool and oxygenate it. It flows at a rate of 2 to 5 Sv and contributes to the overall flow of the AABW. ==Introduction== The Weddell Sea plays an important role in the movement of the world's oceans. An important part of the Weddell Sea is Weddell Sea Bottom Water (WSBW). WSBW is a major contributor to Antarctic Bottom Water (AABW). While WSBW is considered part of AABW, the distinction comes in its potential temperature. The potential temperature of WSBW is -0.7 °C. At this temperature, the potential temperature vs. salinity chart shows a sharp change in slope. The outflow of WSBW is influenced greatly by the Scotia Ridge. The movement of WBSW is listed as 16 Sv which contributes to a total 97 Sv outflow of AABW. 2 to 5 Sv of this production is newly formed bottom water off the Antarctic coast.〔Carmack, Eddy C. and Foster, Theodore D., ''On the Flow of Water out of the Weddell Sea'', Deep-Sea Research, 1975, Vol. 22, pp. 711 to 724.
