Southern Ocean 2001 moorings: LOW PASS ice profiler data from ARSV Laurence M. Gould LMG0103, LMG0201A in the Southern Ocean from 2001-2002 (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>

作为南大洋全球海洋生态系统动力学计划（SO GLOBEC）野外研究的一部分，伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution，简称WHOI）于2001年3月至2002年3月在玛格丽特湾附近部署了一套集成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（图1）。该锚系观测系统获取的参数包括压力、温度、电导率、流速、声学背散射信号以及冰厚。为了在锚系阵列观测期间监测海面强迫过程，研究团队在玛格丽特湾的岛屿上部署了两台自动气象站（Automatic Weather Station，简称AWS），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间序列观测数据。

本研究的核心目标包括：在小时至季节的时间尺度上，测定研究区域内海流及水体物理、生物属性的时空变化特征；深化对该区域大尺度环流的认知与描述；识别并阐明使得该区域成为磷虾（krill）繁衍生存理想场所的物理过程机制。*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>（文件大小10.2 MB）*
