深部大洋温盐环流主要受控于北大西洋深层水的供给量。目前，输送到北大西洋高纬度区域的亚热带温盐水是由北大西洋环流携带的。当其向北运移时，海水冷却并下沉，形成全球深部大洋传送系统。更新世时，高纬度区域海水的盐度和温度均发生了急剧变化。冰期时，由于大气环流... The deep oceanic thermohaline circulation is mainly controlled by the supply of deep water in the North Atlantic Ocean. At present, the subtropical warm brine delivered to the high latitudes of the North Atlantic is carried by the North Atlantic Circulation. As it moves north, seawater cools and sinks, forming a global deep oceanic transport system. During the Pleistocene, the salinity and temperature of seawater in the high latitudes changed dramatically. During the ice age, due to the atmospheric circulation ...
