Current meter components and other data from FIXED PLATFORMS from the South Atlantic Ocean and others locations from 1985-02-23 to 1987-02-01 (NODC Accession 8900031)

Current meter components data were collected from FIXED PLATFORMS in the South Atlantic Ocean and others locations from 23 February 1985 to 01 February 1987. Data were collected by the Woods Hole Oceanographic Institution (WHOI). 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.

本数据集为海流计分量数据，采集时段为1985年2月23日至1987年2月1日，数据来源为南大西洋及其他区域的固定平台（FIXED PLATFORMS）。数据由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）采集，后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。完整格式说明可通过NODC官网链接https://www.nodc.noaa.gov/General/NODC-Archive/f015.html获取。

F015格式存储的是海洋环流的时间序列观测数据，此类数据源自海流计锚系平台，采用欧拉法（Eulerian method）进行海流测量——即海流计固定部署于某一测点，对流经传感器的水流进行观测。每个测站均会记录其站位位置、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）、南北向（v）海流矢量分量数值。海流方向定义为水流流向，以东向和北向为正方向。数据值通常经过平均或滤波处理，采样间隔一般为10至15分钟。数据集还可附带记录水温、压强、电导率或盐度等参数，同时支持添加可选注释的文本记录。
