The Southern Ocean exerts a major influence on the mass balance of the Antarctic Ice Sheet, either indirectly, by its influence on air temperatures and winds, or directly, mostly through its effects on ice shelves. How much melting the ocean causes depends on the temperature of the water, which in turn is controlled by the combination of the thermal structure of the surrounding ocean and local ocean circulation, which in turn is determined largely by winds and bathymetry. As climate warms and atmospheric circulation changes, there will be follow-on changes in the ocean circulation and temperature. These consequences will affect the pace of mass loss of the Antarctic Ice Sheet.
南大洋通过对气温和风的影响，间接对南极冰盖的质量平衡产生重大影响，或者直接通过对冰架的影响来产生重大影响。海洋融化的程度取决于水温，而水温又受到周围海洋热结构和局部海洋环流的共同控制，而海洋环流又在很大程度上取决于风和海底地形。随着气候变暖以及大气环流的变化，海洋环流和温度也会随之发生变化。这些后果将影响南极冰盖质量损失的速度。
