Current meter data from moored current meter casts in the Puget Sound as part of the Mesa Puget Sound/PSERP project, 16 September 1975 - 01 April 1976 (NODC Accession 7601229)

Current meter data were collected using moored current meter casts in the Puget Sound from September 16, 1975 to April 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.

本数据集的海流计数据于1975年9月16日至1976年4月1日期间，在普吉特湾（Puget Sound）通过锚定海流计布放站位采集获得。数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory, PMEL）作为梅萨普吉特湾/PSERP（MESA-PS）项目的一部分提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已按照其制定的海流计数据（F015）标准格式对数据进行处理。完整的锚定海流计布设详情可访问以下网址：http://www.nodc.noaa.gov/General/NODC-Archive/f015.html。

F015格式用于海洋流速的时间序列观测。此类数据源自锚定海流计布设系统，采用欧拉法（Eulerian method）进行海流测量，即海流计固定布设于某一测点，对流经传感器的水流进行观测。每个测站均会记录测点位置、海底水深、传感器埋设深度以及海流计参数等信息。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至15分钟为时间间隔进行记录上报。此外，还可同步记录海水温度、压力、电导率或盐度等参数。数据集附带文本记录，可用于补充备注信息。
