Current and other data from meters attached to fixed platforms in the Beaufort Sea as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 16 May 1978 to 01 November 1978 (NODC Accession 8100005)

Current and other data were collected from meters attached to fixed platforms in the Beaufort Sea by the University of Alaska - Fairbanks (UAF). Data were collected as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 16 May 1978 to 01 November 1978. 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.

海流及相关数据由阿拉斯加大学费尔班克斯分校（University of Alaska-Fairbanks，简称UAF）在波弗特海（Beaufort Sea）的固定平台上部署的海流计采集。本次数据采集作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program，简称OCSEAP）的一部分，采集时间为1978年5月16日至1978年11月1日。数据已由美国国家海洋数据中心（National Oceanographic Data Center，简称NODC）按照NODC标准F015海流计分量格式（F015 Current Meter Components format）完成标准化处理。完整格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/f015.html查阅。本次入库数据集的模拟文件可通过NODC用户服务获取。

F015格式存储海流的时序观测数据。此类数据源自海流计锚系观测，采用欧拉法（Eulerian method）进行海流测量，即通过在固定点位部署海流计，监测流经传感器的水流。每个测站均会记录站位坐标、海底水深、传感器布设深度以及海流计的相关参数。数据记录包含指定日期与时刻下的东西向（u）与南北向（v）海流矢量分量的数值。海流方向定义为水流的流向，其中正东、正北为正方向。数据值可经过平均或滤波处理，通常以10至15分钟为采样间隔进行上报。数据集还可包含水温、压强、电导率或盐度的相关观测数据。此外还可提供文本记录用于填写附加备注。
