ANZFLUX Buoy Analysis

*9615154莫里森拟议的工作是对作为东部韦德尔海上层混合层海洋结构的综合研究计划(“ANZFlux”)的一部分而产生的数据集的扩展分析。它是在1994年南冬从RVIB纳撒尼尔·B·帕尔默进行的。这里提出的工作涉及从锚定在海冰上的漂流浮标测量上层海洋温度、盐度和流速的长时间序列。东部韦德尔海是一个温暖的区域，由温度接近+1摄氏度的温暖的环极地深水入侵定义，和冷的区域并存。寒冷状态出现在西部，那里的深水被厚厚的接近冰冻的混合层覆盖。然而，在这两个地区，季节性地将足够的热量输送到海冰，使其完全融化。拟议工作的具体目标是增进我们对与频繁风暴有关的强烈混合事件如何影响海洋上层和海冰复盖的结构和季节演变的理解。上层的结构反过来影响深海的稳定性，并决定对流的深度和深海温度和盐度的长期变化。*？？

*** 9615154 Morison The proposed work is an extended analysis of a data set generated as part of an integrated research program ("Anzflux") into the oceanographic structure of upper mixed layer of the eastern Weddell Sea. It was carried out from the RVIB Nathaniel B. Palmer in the austral winter of 1994. The work proposed here concerns long time series measurements of upper ocean temperature, salinity, and current speed from a drifting buoy anchored to the sea ice. The eastern Weddell Sea is a region where a warm regime, defined by the intrusion of warm circumpolar deep water with temperatures near +1 deg C, and a cold regime exist side by side. The cold regime occurs to the west, where deep water is overlain by a thick near-freezing mixed layer. In both regions however enough heat is seasonally carried to the sea ice to melt it completely. The specific objective of the proposed work is to improve our understanding of how the intense mixing events associated with frequent storms affect the structure and seasonal evolution of the upper layers of the ocean and the sea ice cover. The structure of the upper layers in turn affects the stability of the deeper ocean, and determines the depth of convection and the longer term variability in temperature and salinity of the deep ocean. *** ??
