Long-Term Oceanographic Monitoring in Massachusetts Bay (1989-2006) for Assessment of the Transport and Fate of Sediments and Associated Contaminants.

Long-term oceanographic observations made in western Massachusetts Bay at long-term site LT-A (42 degrees 22.6 minutes N., 70 degrees 47.0 minutes W.; nominal water depth 32 meters) from December 1989 through February 2006 and long-term site B LT-B (42 degrees 9.8 minutes N., 70 degrees 38.4 minutes W.; nominal water depth 22 meters) from October 1997 through February 2004 are presented here. The observations were collected as part of a U.S. Geological Survey (USGS) study designed to understand the transport and long-term fate of sediments and associated contaminants in Massachusetts Bay. The observations include time-series measurements of current, temperature, salinity, light transmission, pressure, oxygen, fluorescence, and sediment-trapping rate. About 160 separate mooring or tripod deployments were made on about 90 research cruises to collect these long-term observations. This report presents a description of the 17-year field program and the instrumentation used to make the measurements, an overview of the data set, more than 2,500 pages of statistics and plots that summarize the data, and the digital data in Network Common Data Form (NetCDF) format. This research was conducted by the USGS in cooperation with the Massachusetts Water Resources Authority and the U.S. Coast Guard.

http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2003-003-FA本数据集收录了马萨诸塞湾西部两处长期观测站点的海洋学长期观测数据：LT-A站点（北纬42°22.6′，西经70°47.0′，标称水深32米）的观测时段为1989年12月至2006年2月，LT-B站点（北纬42°9.8′，西经70°38.4′，标称水深22米）的观测时段为1997年10月至2004年2月。 本次观测数据为美国地质调查局（U.S. Geological Survey, USGS）相关研究的组成部分，该研究旨在探明马萨诸塞湾内沉积物及其伴生污染物的运移过程与长期归宿。观测内容涵盖海流、温度、盐度、透光率、压力、溶解氧、荧光强度以及沉积物捕获率的时序测量数据。为获取上述长期观测数据，研究团队依托约90个调查航次，完成了共计约160套锚系或三脚架装置的布放作业。 本报告详细介绍了这项为期17年的野外调查计划及配套观测仪器，对本数据集进行了整体概述，提供了超过2500页用于总结数据的统计图表，并附带了网络通用数据格式（Network Common Data Form, NetCDF）的数字化原始数据。 本研究由美国地质调查局联合马萨诸塞州水资源管理局与美国海岸警卫队共同开展。如需了解与数据采集相关的野外作业详情，请访问以下链接：
