Current meter and other data from FIXED PLATFORMS from NW Atlantic (limit-40 W) as part of the Outer Continental Shelf (OCS) and other projects from 1982-11-10 to 1984-11-01 (NCEI Accession 8600090)

Current meter data were collected from fixed platforms in NW Atlantic (limit-40 W) from 10 November 1982 to 01 November 1984. Data were submitted by the Woods Hole Oceanographic Institution (WHOI) as part of the Outer Continental Shelf (OCS) and other projects. 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.

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.

本数据集的海流计观测数据采集于1982年11月10日至1984年11月1日期间的西北大西洋海域（以西经40°为界）。该数据由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）提交，作为外大陆架（Outer Continental Shelf, OCS）及其他研究项目的一部分。数据由国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准F015海流计分量格式进行处理。完整的格式说明可通过NODC官网的https://www.nodc.noaa.gov/General/NODC-Archive/f015.html获取。

F015格式存储的是海洋海流的时序观测数据。此类数据源自海流计锚系观测，采用欧拉海流测量方法，即：将海流计部署于固定点位，通过传感器采集流经该点的水流数据。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设备参数。数据记录包含指定日期与时刻下的东西向（u）与南北向（v）海流矢量分量数值。海流方向定义为水流流向，其中东向与北向为正方向。观测数据可经过平均或滤波处理，通常以10至15分钟为间隔进行记录报送。此外，数据中还可包含水温、压强、电导率或盐度的观测值。同时预留文本记录字段以供填写可选备注信息。
