Current meter components and other data from FIXED PLATFORMS from NW Atlantic (limit-40 W) from 1982-07-08 to 1982-08-01 (NODC Accession 8600040)

Current meter components data were collected from FIXED PLATFORMS in the NW Atlantic (limit-40 W) from 08 July 1982 to 01 August 1982. 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.

本数据集为海流计组件观测数据（Current Meter Components Data），采集于1982年7月8日至1982年8月1日期间西北大西洋（西经40°以西洋区）的固定平台之上。数据由伍兹霍尔海洋研究所（Woods Hole Oceanographic Institution，WHOI）采集，经美国国家海洋数据中心（National Oceanographic Data Center，NODC）处理为NODC标准F015海流计组件格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f015.html获取。

F015格式存储海洋环流的时间序列观测数据，其数据源为海流计锚系测站，采用欧拉法（Eulerian Method）进行海流测量——即传感器部署于固定点位，直接测量流经传感器的水流流速。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设备参数。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。海流方向定义为水流的流向，正东与正北为正方向。观测数据可经过平均或滤波处理，通常以10~15分钟的时间间隔进行输出。数据集还可包含海水温度、压强、电导率或盐度等辅助观测参数，同时支持附加文本注释记录。
