Cape Adare Long Term Moorings (CALM): Analysis Phase

从海洋系泊处获得的关于海洋特性演变关键方面的时间序列数据对于评估海洋系统的状况具有相当重要的意义。例如，他们需要了解海洋是如何变暖的，以及海洋是如何继续吸收二氧化碳等温室气体的。阿代尔角长期系泊（CALM）项目的目标是观察从罗斯海到深海的底水出口。为了完成这一任务，在Adare角（南极洲罗斯海西部）的大陆斜坡上设置了两个仪器系泊，定位于捕捉南极底水（AABW）的出口，这是全球海洋中最冷、密度最大的水。在这片非常偏远的海域，系泊点的数据记录跨越了大约四年。CALM分析将解决一些具体目标：？描述与罗斯海AABW出口相关的温度、盐度和电流变化。考察观测到的变率与区域潮汐、大气和海冰强迫之间的联系。将罗斯海AABW输出波动与更大尺度的气候系统动力学（如ENSO和SAM）以及南极洲其他边缘（如威德尔海）的AABW形成联系起来

Time series data, from ocean moorings, on key aspects of evolving ocean properties are of considerable importance in assessing the condition of the ocean system. They are needed, for example, their understand how the oceans are warming, and how they continue to uptake greenhouse gases such as CO2. The Cape Adare Long Term Mooring (CALM) program goal was to observe the bottom water export from the Ross Sea to the deep ocean. To accomplish this two instrumented moorings were set on the continental slope off Cape Adare (western Ross Sea, Antarctica), positioned to capture the export of Antarctic Bottom Water (AABW), some of the coldest and densest water found in the global ocean. Data records for the moorings spans over some four years in this very remote part of the ocean. The CALM analysis will address some specific objectives:? Characterize the temperature, salinity and current variability associated with the Ross Sea AABW export.? Examine the linkages between observed variability to regional tides, atmosphere and sea ice forcing.? Relate the Ross Sea AABW export fluctuations to the larger scale climate system dynamics, such as ENSO and SAM, and to AABW formation along other margins of Antarctica, e.g. the Weddell Sea
