Current and other data from meters attached to fixed platforms as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 02 July 1974 to 01 September 1974 (NODC Accession 7900149)

Current and other data were collected from meters attached to fixed platforms by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS). Data were collected as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 02 July 1974 to 01 September 1974. 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数据，由阿拉斯加大学费尔班克斯分校海洋科学研究所（UAK/IMS）通过安装在固定平台上的测量仪采集获取。这些数据作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分，于1974年7月2日至1974年9月1日期间采集。数据由国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准F015海流计组件格式完成处理。完整的格式说明可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/f015.html查询获取。本数据集的模拟文件可通过NODC用户服务渠道获取。
F015格式包含海流的时间序列测量数据。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，即测量仪部署于固定点位，对流经传感器的水流进行监测。每个测站均会记录其位置、海底水深、传感器布设深度以及测量仪的相关参数。数据记录包含指定日期与时间下的东西向（u）与南北向（v）海流矢量分量数值。海流方向定义为水流流向，以东向与北向为正方向。数据值可经过平均或滤波处理，通常以10至15分钟为时间间隔进行记录上报。数据中还可附带记录水温、压强以及电导率或盐度相关参数。同时提供文本记录用于填写可选备注信息。
