Current meter data from moored current meter casts in the North Atlantic Ocean as part of the Outer Continental Shelf - Georges Bank (OCS -Georges Bank) project from 08 September 1978 - 01 October 1979 (NODC Accession 8100506)

Current meter data were collected using moored current meter casts in the North Atlantic Ocean from September 8, 1978 to October 1, 1979. Data were submitted by Edgerton, Germeshausen and Grier, INC. as part of the Outer Continental Shelf - Georges Bank (OCS -Georges Bank) 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采集于1978年9月8日至1979年10月1日期间，采用锚定海流计布放作业获取于北大西洋海域。数据由埃奇顿、杰梅豪森与格里尔公司（Edgerton, Germeshausen and Grier, INC.）提交，作为外大陆架——乔治浅滩（Outer Continental Shelf - Georges Bank，OCS-Georges Bank）项目的组成部分。数据已由国家海洋数据中心（National Oceanographic Data Center，NODC）整理为海流计数据（F015）标准格式。完整的锚定海流计布放说明可访问网址：http://www.nodc.noaa.gov/General/NODC-Archive/f015.html。

F015格式用于海流的时间序列测量。此类数据源自锚定海流计布放，采用欧拉法（Eulerian method）进行海流观测，即传感器布设于固定点位，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、传感器埋设深度以及海流计的技术参数。数据记录包含指定日期与时刻下的东-西向（u）和北-南向（v）海流矢量分量值。海流方向定义为水流实际流向，以东向与北向为正方向，西向与南向为负方向。数据值可经过平均或滤波处理，通常以10~15分钟的时间间隔进行输出记录。数据中还可附带水温、压强、电导率或盐度等辅助参数。此外可提供文本记录用于添加可选备注。
