Southern Ocean 2002 moorings: LOW PASS current data from ARSV Laurence M. Gould LMG0201A, LMG0302 in the Southern Ocean from 2002-2003 (SOGLOBEC project)

<p>\"As part of the SO GLOBEC field program, the Woods Hole Oceanographic Institution (WHOI) deployed an array of instrumented subsurface moorings near Marguerite Bay during March 2001- March 2002 and a second array during March 2002-March 2003 (Figure 1). The moored measurements included pressure, temperature, conductivity, velocity, acoustic backscatter, and ice thickness. To monitor surface forcing during the moored array observations, two automatic weather stations (AWSs) were deployed on islands in Marguerite Bay and time series of wind, air temperature, pressure, and relative humidity were collected from May 2001 through March 2003.</p> <p>The primary goals of this effort were to measure the temporal and spatial variability of currents and physical and biological water properties in the study area on time scales from hours to seasonal, improve our description and understanding of the regional general circulation, and identify and describe those physical processes that make this region well suited for krill production and survival.\" <em>[from technical report <a href=\"http://globec.whoi.edu/so-dir/data_doc/WHOI-2005-07_Moored_Report_updated.pdf\" target=\"_blank\">WHOI-2005-07.pdf</a> (10.2 MB)]</em></p>作为SO GLOBEC野外科考计划的组成部分，伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution，WHOI）于2001年3月至2002年3月在玛格丽特湾附近部署了一套搭载观测仪器的水下锚系阵列，并于2002年3月至2003年3月部署了第二套锚系阵列（见图1）。该锚系阵列的观测项目涵盖压力、温度、电导率、海流流速、声学背散射强度以及海冰厚度。为在锚系阵列观测期间同步监测海面强迫过程，研究团队于玛格丽特湾内的岛屿上部署了两台自动气象站（Automatic Weather Stations，AWSs），并于2001年5月至2003年3月期间采集了风速、气温、气压及相对湿度的时序观测数据。 本次科考工作的核心目标包括：在小时至季节的时间尺度上，测定研究区域内海流与水体物理、生物特性的时空变异性；完善对该区域大尺度环流的描述与认知；并识别并阐明那些使本区域极适宜磷虾繁殖与存活的物理过程。*[资料来源：技术报告 <a href="http://globec.whoi.edu/so-dir/data_doc/WHOI-2005-07_Moored_Report_updated.pdf" target="_blank">WHOI-2005-07.pdf</a>（10.2 MB）]*
