Current meter data from moored current meter casts in the Caribbean Sea as part of the Ocean Thermal Energy Conversion (OTEC) project from 15 February 1979 - 01 February 1980 (NODC Accession 8100608)

Current meter data were collected using moored current meter casts in the Caribbean Sea from February 15, 1979 to February 1, 1980. Data were submitted by University of California -Berkley as part of the Ocean Thermal Energy Conversion (OTEC) 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（current meter）数据采集自加勒比海海域，采用锚定海流计布放方式获取，观测时段为1979年2月15日至1980年2月1日。数据由加州大学伯克利分校（University of California, Berkeley）作为海洋热能转换（Ocean Thermal Energy Conversion, OTEC）项目的一部分提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）将数据处理为NODC标准海流计数据格式（F015）。完整的锚定海流计锚系装置说明可访问以下网址：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系统，采用欧拉法（Eulerian method）进行海流测量，即通过将海流计部署于固定点位，测量流经传感器的海水流动情况。每个测站均会记录站位坐标、海底水深、传感器埋设深度以及海流计参数信息。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。海流方向定义为海水的流动去向，东向与北向为正方向，西向与南向为负方向。数据值可经过平均处理或滤波降噪处理，通常以10至15分钟的时间间隔进行输出。数据集还可同步记录海水温度、压力、电导率或盐度等辅助观测参数，同时预留文本记录字段以供填写补充注释。
