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 1981-05-10 to 1982-06-01 (NODC Accession 8300059)

Current meter data were collected using moored current meter casts in the North Atlantic Ocean from May 10, 1981 to June 1, 1982. 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.本数据集的海流计数据采集于1981年5月10日至1982年6月1日期间的北大西洋海域，通过锚定海流计观测站位获取。数据由北卡罗来纳州罗利市的科学应用公司（Science Applications, INC.）提交，作为南大西洋外大陆架（Outer Continental Shelf - South Atlantic，简称OCS-South Atlantic）项目的组成部分。数据由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准海流计数据（Current Meter Data, F015）格式。完整的锚定海流计布设详情可通过以下链接获取：http://www.nodc.noaa.gov/General/NODC-Archive/f015.html。 F015格式专用于海洋环流的时间序列观测。此类数据源自锚定海流计观测，采用海流测量的欧拉法（Eulerian method）：即将海流计部署于固定点位，测量流经传感器的水流。每个观测站位均需报告点位坐标、海底水深、传感器布设深度以及海流计的参数信息。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的流向：正东与正北为正方向，正西与正南为负方向。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。数据中还可同步记录海水温度、压力、电导率或盐度等参数。此外还提供文本记录字段，用于填写可选备注信息。
