Current meter data from moored current meter casts in the Pacific Ocean as part of the Equatorial Pacific Ocean Climate Studies (EPOCS) project from 1986-05-28 to 1987-05-11 (NODC Accession 8900168)

Current meter data were collected using moored current meter casts in the Pacific Ocean from 28 May 1986 to 01 May 1983. Data were submitted by Pacific Marine Environmental Laboratory (PMEL) as part of the Equatorial Pacific Ocean Climate Studies (EPOCS) 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.

本数据集的海流计数据于1986年5月28日至1983年5月1日期间，在太平洋海域通过锚定海流计布放作业采集获取。数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory, PMEL）作为赤道太平洋气候研究（Equatorial Pacific Ocean Climate Studies, EPOCS）项目的一部分提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将数据处理为符合其标准的海流计数据（F015）格式。完整的海流计锚系站点描述可通过http://www.nodc.noaa.gov/General/NODC-Archive/f015.html查阅获取。

F015格式专用于海洋海流的时间序列观测。此类数据源自锚定海流计阵列，采用欧拉法进行海流测量，即海流计布设于固定点位，通过传感器感知流经的水流。每个测站均会记录站位坐标、海底水深、传感器布设深度以及海流计的参数信息。数据记录包含指定日期与时刻下的东-西向（u）与北-南向（v）海流矢量分量数值。海流流向定义为水流运动的指向：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处理，通常以10至15分钟的时间间隔进行记录上报。数据集同时可附带记录海水温度、压强以及电导率或盐度数据。另有文本记录字段可供添加可选备注。
