Drifting buoy and other data from the Beaufort Sea as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 05 November 1975 to 01 October 1976 (NODC Accession 7700019)

Drifting buoy and other data was collected from the Beaufort Sea by the University of Washington (UW) as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were collected from 05 November 1975 to 01 October 1976. Data were processed by NODC to the NODC standard F156 Drifting Buoy Data format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f156.html. An analog file for this accession is available from NODC user service.

The F156 format is used for time series data on ocean circulation determined by the tracking of drifting buoys, drogues, or other instrumented devices as they are carried with the flow. Movement is reported as point-to-point geographic locations determined by shore-based, surface ship, aircraft, or satellite observations. Data from both ocean currents and ice movement can be reported in this format over time periods ranging from minutes to months. Directions and speeds between individual observations may be computed from these data and presented in graphic or summary listing form to provide information on circulation patterns and mass transport in offshore and near- shore regions. Platform name (for platform acquiring data or deploying device), drogue characteristics, start and end positions and times, and observation frequency (if constant time interval) are reported for each series of observation. Other surface meteorological or oceanographic parameters (e.g., water temperature and salinity, air temperature and pressure, wind, waves) and subsurface data (depth, pressure, temperature) may also be reported. Text records may be used to report general comments or to describe individual drogue observations.

本数据集包含从波弗特海采集的漂流浮标及其他相关数据，由华盛顿大学（University of Washington, UW）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分开展采集工作。数据采集时段为1975年11月5日至1976年10月1日，后经国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准F156漂流浮标数据格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f156.html获取，本次入库数据的模拟文件可通过NODC用户服务渠道获取。
F156格式用于存储通过追踪漂流浮标、曳航浮标（drogue）或其他搭载传感器的设备随流运动所得的海洋环流时序数据。设备的运动以经岸基、水面舰艇、航空器或卫星观测得到的逐点地理坐标进行记录。该格式可支持存储时长从数分钟至数月不等的海流及海冰运动数据。基于此类数据可计算得到两次观测间的运动方向与速度，并以图表或汇总列表形式呈现，用以提供近海及近岸区域的环流模式与物质输运相关信息。每套观测序列需记录以下信息：搭载数据采集设备或部署观测装置的平台名称、曳航浮标参数、起止位置与时间，以及观测频次（若为固定时间间隔）。此外，该格式还可收录其他表层气象或海洋学参数（如水温、盐度、气温、气压、风况、海浪）以及次表层数据（深度、压力、温度）。文本记录可用于补充通用说明或描述单条曳航浮标观测详情。
