Current meter components and other data from FIXED PLATFORMS from 1977-10-25 to 1987-06-22 (NODC Accession 9400196)

Current meter components data were collected from FIXED PLATFORMS from 15 June 1982 to 01 July 1982. Data were collected by the Fisheries Laboratory - Lowestoft and other institutions. 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于1982年6月15日至1982年7月1日，采集载体为固定平台。数据由洛斯托夫特渔业实验室（Fisheries Laboratory - Lowestoft）及其他相关机构共同采集，后由美国国家海洋数据中心（NODC）按照NODC标准F015海流计组件格式完成标准化处理。完整格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/f015.html查阅获取。

F015格式存储的为海洋环流时间序列观测数据，其数据来源为海流计锚系浮标，采用欧拉法（Eulerian method）进行海流测量，即海流计布设于固定点位，通过传感器监测流经该点的水流。每个测站均需记录站位位置、海底水深、传感器布设深度以及海流计的相关参数信息。数据记录包含指定日期与时刻下的东西向（u）与南北向（v）海流矢量分量数值。海流方向定义为水流实际流向，以东向与北向为正方向。原始观测数据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输出。此外，数据集还可包含水温、压强、电导率或盐度等辅助观测参数，同时预留了文本记录字段用于填写可选备注信息。
