Current meter - direction and other data from FIXED PLATFORMS in support of the MESA PUGET SOUND/PSERP (MESA-PS) project from 01 April 1976 to 08 November 1976 (NODC Accession 7800015)

Current meter - direction and other data were collected from FIXED PLATFORMS from 01 April 1976 to 08 November 1976. Data were collected by the National Ocean Service (NOS) in support of the MESA PUGET SOUND/PSERP (MESA-PS) project. Data were processed by NODC to the NODC standard F005 - Current Meter Data (Resultants) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f005.html.

The F005 format is used for time series measurements of ocean currents obtained using moored current-measuring instruments, principally Aanderaa current meters (manufactured by Aanderaa Instruments Inc.). These data represent the Eulerian method of current measurement, i.e., the meters are deployed at a fixed mooring point and measure flow past the sensor. Position, water depth, and sensor depth are reported for each station. The data record comprises values of current direction and speed at specified date and time. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Other environmental parameters may also be reported. These include: water temperature, salinity, conductivity, and transmissivity; wind direction and speed; and dominant wave direction, height, and period. A text field is available for optional comments.

本数据集收录1976年4月1日至1976年11月8日期间，通过固定平台采集的海流计（current meter）流向及其他相关观测数据。该数据由美国国家海洋服务局（National Ocean Service, NOS）为支撑MESA普吉特湾/PSERP（MESA-PS）项目采集，后经美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准F005——海流计数据（合成值）格式完成处理。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f005.html查阅。

F005格式用于锚泊式海流测量仪器获取的海流时间序列数据，主流测量设备为安德拉海流计（Aanderaa current meters，由Aanderaa仪器公司（Aanderaa Instruments Inc.）制造）。本次观测采用欧拉法（Eulerian method）进行海流测量，即海流计部署于固定锚泊点位，对流经传感器的水流进行监测。每个测站均会记录其位置、水深及传感器布设深度。数据记录包含指定日期与时刻下的海流流向与流速数值，数据可经平均或滤波处理，通常以10至15分钟的时间间隔进行上报。数据集还可附带其他环境参数，包括水温、盐度、电导率、透射率；风向与风速；以及主波向、波高与波周期。此外还预留了文本字段用于填写可选备注信息。
