Current meter data from moored current meter casts in the North Atlantic Ocean as part of the Outer Continental Shelf - South Atlantic (OCS-South Atlantic) project from 1981-05-11 to 1981-11-01 (NCEI Accession 8200003)

Current meter data were collected using moored current meter casts in the North Atlantic Ocean from May 11, 1981 to November 1, 1981. Data were submitted by Science Applications, INC. - Raleigh NC as part of the Outer Continental Shelf - South Atlantic (OCS-South Atlantic) project. Data were processed by NODC to the NODC standard Current Meter Data (F015) format. Full current meter moorings descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/f015.html.

The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent 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 comprises 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 and negative directions west and south. 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.

本数据集的海流计（current meter）数据采集于1981年5月11日至1981年11月1日期间，采用锚泊海流计作业方式在北大西洋海域完成。数据由位于北卡罗来纳州罗利市的科学应用公司（Science Applications, INC.）作为南大西洋外大陆架（Outer Continental Shelf - South Atlantic, OCS-South Atlantic）项目的一部分提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将数据处理为NODC标准海流计数据（Current Meter Data, F015）格式。完整的锚泊海流计布设说明可通过以下网址获取：http://www.nodc.noaa.gov/General/NODC-Archive/f015.html。

F015格式用于海洋流速的时间序列测量。此类数据源自锚泊海流计，采用欧拉法（Eulerian method）进行流速测量，即海流计被部署于固定点位，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）与北-南向（v）流速矢量分量数值。海流方向定义为水流的流向，正东与正北为正方向，正西与正南为负方向。数据数值可经过平均化或滤波处理，通常以10至15分钟的时间间隔进行记录与上报。此外还可同步记录海水温度、压强以及电导率或盐度数据。附带的文本记录可用于添加可选备注信息。
