As a result of the paucity of winter data in the Southern Ocean, sophisticated ocean models such as the GFDL MOM are hampered in their ability to properly represent the complex processes in the Antarctic sea ice zone. Elephant seals forage in the Southern Ocean throughout winter, and traverse the water column between 0 and 800 metres many times each day, providing an opportunity to collect profiles of temperature and salinity. The resulting data will contribute to oceanographic studies of water mass formation and frontal variability, including comparisons with historical data and assimilation into a complex ocean model.

由于南大洋冬季数据的缺乏，复杂的海洋模式，如GFDL MOM，在正确反映南极海冰带复杂过程的能力方面受到阻碍。整个冬季象海豹都在南大洋觅食，每天要在0到800米之间的水柱上穿梭多次，这为收集温度和盐度剖面提供了机会。所得数据将有助于对水团形成和锋面变率的海洋学研究，包括与历史数据的比较和同化到一个复杂的海洋模式中。
