Depth of the Antarctic Circumpolar Wave and Interactions with the Sea Ice Pack Forming Annually in the Seas around Antarctica

PI：White Proposal Number：9910730 Funds用于统计分析海面温度、海平面高度、海冰面积、海冰密度、表层气温、海平面气压、表层风、温度分布、盐度分布和漂流速度等历史数据集，以更好地了解南极绕极波(ACW)的结构，这是最近描述的气候系统的一个特征。特别是，调查人员将确定ACW信号出现在海面以下的深度及其对主要跃层的影响。他们还将确定ACW和韦德尔海和罗斯海海冰密度之间的一致性。这将有助于解释ACW在南极底层水形成中的潜在作用。

PI: WhiteProposal Number: 9910730Funds are provided for the statistical analysis of historical data sets of sea surface temperature, sea level height, sea ice extent, sea ice concentration, surface air temperature, sea level pressure, surface wind, temperature profiles, salinity profiles, and drifter velocities to better understand the structure of the Antarctic Circumpolar Wave (ACW), a recently described feature of the climate system. In particular, the investigators will determine the depth to which the ACW signal occurs below the sea surface and its effect on the main pycnocline. They will also determine the coherence between the ACW and sea ice concentration in the Weddell and Ross Seas. This will assist in interpreting the potential role of the ACW in the formation of Antarctic Bottom Water.
