Current and other data from meters attached to fixed platforms in the Beaufort Sea and other locations as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 19 September 1977 to 30 October 1978 (NODC Accession 7900257)

Current and other data were collected from meters attached to fixed platforms in the Beaufort Sea and other locations by the University of Washington (UW) from 19 September 1977 to 30 October 1978. Data were collected as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F015 Current Meter Components format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f015.html. An analog file for this accession is available from NODC user services.

The F015 format contains time series measurements of ocean currents. These data are obtained from current meter moorings and represent the Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth and meter characteristics are reported for each station. The data record includes values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north. Data values may be subject to averaging or filtering and are typically reported at 10 - 15 minute time intervals. Water temperature, pressure and conductivity or salinity may also be reported. A text record is available for optional comments.

本数据集的海流及其他相关观测数据，由华盛顿大学（University of Washington，UW）于1977年9月19日至1978年10月30日期间，通过部署在波弗特海及其他海域固定平台上的海流计采集获得。本次数据采集作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program，OCSEAP）的一部分实施。美国国家海洋数据中心（National Oceanographic Data Center，NODC）已将该数据处理为符合NODC标准的F015海流分量格式。完整格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/f015.html查询。本数据集的模拟文件可通过NODC用户服务渠道获取。

F015格式用于存储海流的时间序列测量数据，此类数据源自海流计锚系测站，采用欧拉海流测量方法（Eulerian method）：即海流计固定布设至某一测点，对流经传感器的水流进行监测。每份测站记录均包含测点位置、海底水深、传感器布设深度以及海流计参数信息。数据记录包含指定日期与时刻下的东-西向（u）与北-南向（v）海流矢量分量。海流方向定义为水流流向，正东与正北为正方向。数据值通常经过平均或滤波处理，采样间隔一般为10至15分钟。此外，数据中还可能包含水温、压强、电导率或盐度等观测参数。数据集附带文本记录，用于填写可选备注信息。
