Drifting buoy and other data from the Arctic Ocean and Beaufort Sea as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 04 November 1975 to 01 October 1976 (NODC Accession 7700114)

Drifting buoy data was collected from the Arctic Ocean and Beaufort Sea by the University of Washington (UW) as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were collected from 04 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.

本漂流浮标数据由华盛顿大学（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，于北冰洋与波弗特海海域采集。数据采集时段为1975年11月4日至1976年10月1日，后由美国国家海洋数据中心（National Oceanographic and Data Center，NODC）按照NODC标准F156漂流浮标数据格式完成标准化处理。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f156.html获取，本归档条目的模拟文件可通过NODC用户服务渠道获取。

F156格式适用于处理通过追踪漂流浮标、曳航浮具（drogue）或其他搭载仪器的装置随流运动所获取的海洋环流时序数据。浮标运动以岸基、水面船舶、航空器或卫星观测得到的逐点地理坐标进行记录。该格式可支持记录海洋环流与海冰运动的时序数据，覆盖时长范围从数分钟至数月不等。可基于单条观测数据计算相邻观测间的运动方向与速率，并以图表或汇总列表形式呈现，用以提供近岸与离岸海域的环流模式及物质输运相关信息。每套观测序列需记录以下信息：搭载数据采集或装置部署的平台名称、曳航浮具参数、起始与终止位置及时间，以及观测频率（若为固定时间间隔）。此外，该格式还可记录其他表面气象或海洋学参数（如水温、盐度、气温、气压、风向风速、海浪状况）以及次表层数据（深度、压强、温度）。文本记录可用于填写通用备注或描述单条曳航浮具观测数据。
