Current meter components and other data from FIXED PLATFORMS from 1978-05-01 to 1979-07-01 (NODC Accession 8500082)

Current meter components data were collected from FIXED PLATFORMS from 01 May 1978 to 01 July 1979. 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.

本数据集的海流计分量数据采集自固定平台（FIXED PLATFORMS），采集时段为1978年5月1日至1979年7月1日，由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution, WHOI）负责采集。数据由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为符合NODC标准的F015海流计分量格式文件。完整格式说明可通过NODC官网的https://www.nodc.noaa.gov/General/NODC-Archive/f015.html查阅。

F015格式存储的是海洋环流的时间序列观测数据，这类数据取自海流计锚系装置，采用欧拉法（Eulerian method）进行海流测量——即海流计被部署于固定点位，通过传感器监测流经该点的水流。每个测站均会记录其位置、海底水深、传感器埋设深度以及海流计的参数特征。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的流向，以东向与北向为正方向。数据数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上报。此外，数据集还可包含水温、压强、电导率或盐度的观测数据。同时提供文本记录字段，用于填写可选备注信息。
