Current meter data from moored current meter casts in the Coastal Waters of SE Alaska/Brit.Colum. as part of the Long-Range Effects Program Puget Sound project from 1983-03-15 to 1983-11-01 (NODC Accession 8600321)

Current meter data were collected using moored current meter casts in the Coastal Waters of SE Alaska/Brit.Colum. from March 15, 1983 to November 1, 1983. Data were submitted by Pacific Marine Environmental Laboratory (PMEL) as part of the Long-Range Effects Program Puget Sound 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.

1983年3月15日至1983年11月1日期间，研究人员在阿拉斯加东南部/不列颠哥伦比亚省近岸海域，通过锚定式海流计布放作业采集了海流计观测数据。该数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory, PMEL）作为普吉特海湾长效影响项目的组成部分提交，后由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准海流计数据（F015）格式。完整的锚定海流计站点说明可访问链接：http://www.nodc.noaa.gov/General/NODC-Archive/f015.html。

F015格式专用于海洋环流的时间序列观测。本批次数据源自锚定海流计站点，采用欧拉法进行海流测量——即仪器布设于固定点位，通过传感器采集流经的水流数据。每个观测站点均记录了站点位置、海底水深、传感器布设深度以及海流计参数信息。数据记录包含指定日期时间下的东西向（u）与南北向（v）海流矢量分量数值。海流流向定义为水流运动的指向：东向与北向为正方向，西向与南向为负方向。观测数据可经过平均或滤波处理，通常以10至15分钟的时间间隔进行上报。数据中还可同步记录海水温度、压力、电导率或盐度参数。此外可附带文本记录以填写补充说明。
