Current meter components and other data from FIXED PLATFORMS from Gulf of Guinea and other locations as part of the Equatorial Pacific Ocean Climate Studies (EPOCS) and other projects from 08 July 1976 to 01 April 1982 (NODC Accession 9000067)

Current meter components data were collected from FIXED PLATFORMS in the Gulf of Guinea and other locations from 08 July 1976 to 01 April 1982. Data were collected by the University of South Florida (USF) as part of the Equatorial Pacific Ocean Climate Studies (EPOCS) 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.

本数据集的海流计组件数据采集于1976年7月8日至1982年4月1日期间，采集地点为几内亚湾及其他区域的固定平台。此类数据由南佛罗里达大学（University of South Florida, USF）作为赤道太平洋海洋气候研究（Equatorial Pacific Ocean Climate Studies, EPOCS）及其他项目的一部分完成采集。数据已由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准F015海流计组件格式进行标准化处理。完整的格式说明可从NODC官网www.nodc.noaa.gov/General/NODC-Archive/f015.html获取。
F015格式用于存储海洋环流的时间序列测量数据，此类数据源自海流计锚系观测，采用欧拉流场测量方法：即测量设备部署于固定点位，监测流经传感器的流体运动。每个测站均会记录其地理位置、海底水深、传感器埋设深度以及测量设备的相关参数。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。海流方向定义为水流的流向，正东与正北为正方向。数据值可能经过平均或滤波处理，通常以10至15分钟的时间间隔进行上报。此外，数据还可同步记录海水温度、压强以及电导率或盐度参数。数据附带可选的文本记录，用于添加补充备注信息。
