Cape Adare Long Term Moorings (CALM): Analysis Phase

来自海洋系泊设备的关于不断变化的海洋特性的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，以及他们如何继续吸收二氧化碳等温室气体。阿代尔角长期系泊（CALM）计划的目标是观察从罗斯海到深海的底层水输出。为了实现这一目标，在阿代尔角（南极洲罗斯海西部）外的大陆坡上设置了两个仪器化系泊装置，用于捕获南极底层水（AABW）的出口，这是全球海洋中发现的一些最冷和最密集的水。在这个非常偏远的海洋地区，系泊设备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输出相关的温度、盐度和海流变化。研究观测到的变化与区域潮汐、大气和海冰强迫之间的联系。将罗斯海AABW输出波动与ENSO和SAM等大尺度气候系统动力学以及威德尔海等南极洲其他边缘沿着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
