Current meter components and other data from FIXED PLATFORMS from 11 January 1975 to 06 May 1975 (NODC Accession 7700285)

Current meter components data were collected from fixed platforms from 11 January 1975 to 06 May 1975. Data were collected by the University of Washington (UW). 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，采集时段为1975年1月11日至1975年5月6日，数据采集自固定平台，由华盛顿大学（University of Washington, UW）完成原始采集工作，后经国家海洋数据中心（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官网获取，网址为www.nodc.noaa.gov/General/NODC-Archive/f015.html。 F015格式包含海流的时间序列测量数据，此类数据源自海流计锚系系统，采用欧拉法（Eulerian method）进行海流测量：即海流计部署于固定点位，测量流经传感器的流体流速。每个测站均记录其地理位置、海底水深、传感器布设深度及海流计参数信息。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输出。数据集还可附带水温、压强、电导率或盐度等辅助观测数据，同时提供文本记录字段用于添加可选注释。
