Current meter components and other data from FIXED PLATFORMS from the Greenland Sea from 1989-05-19 to 1990-07-01 (NODC Accession 9100065)

Current meter components data were collected from FIXED PLATFORMS in the Greenland Sea from 19 May 1989 to 01 July 1990. Data were collected by the Pacific Marine Environmental Laboratory (PMEL). 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.本数据集为海流计分量数据，采集于1989年5月19日至1990年7月1日期间的格陵兰海固定平台。数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory，PMEL）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海流计分量格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f015.html获取。 F015格式包含海洋环流的时序测量数据，此类数据源自海流计锚系观测，采用欧拉法进行海流测量——即海流计部署于固定点位，测量流经传感器的水流运动。每个测站均会记录其位置、海底深度、传感器布设深度以及海流计的相关参数。数据记录包含指定日期与时刻下的东西向（u）与南北向（v）海流矢量分量数值。海流方向定义为水流流向，正东与正北为正方向。数据值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记录。此外，数据中还可附带水温、压强、电导率或盐度等参数，同时提供可选的文本注释记录。
