Current meter data from moored current meter casts in the Puget Sound as part of the Mesa Puget Sound/PSERP project, 13 February 1976 - 01 May 1976 (NODC Accession 7601638)

Current meter data were collected using moored current meter casts in the Puget Sound from February 13, 1976 to May 1, 1976. Data were submitted by Pacific Marine Enivornmental Laboratory (PMEL) as part of the Mesa Puget Sound/PSERP (MESA - PS) 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（current meter）观测数据，于1976年2月13日至1976年5月1日期间，在普吉特海湾（Puget Sound）通过锚定式海流计（moored current meter）布放作业采集获取。数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory，PMEL）作为《梅萨普吉特海湾/PSERP（MESA-PS）》项目的组成部分提交。数据集已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。完整的锚定式海流计布放说明可通过以下链接获取：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测量。此类数据源自锚定式海流计布设系统，采用欧拉法（Eulerian method）开展海流观测：即海流计固定部署于某一测点，对流经传感器的水流进行流量监测。每个测站均需记录其地理位置、海底水深、传感器布设深度以及海流计的特性参数。数据记录包含指定日期与时刻下的东-西向（u）与北-南向（v）海流矢量分量数值。海流方向定义为水流的流向方位：正东、正北为正方向，正西、正南为负方向。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输出记录。数据中还可同步附带水温、压强以及电导率或盐度相关参数。数据集预留文本记录字段，用于填写可选备注信息。
