Current meter - direction and other data from FIXED PLATFORMS in support of the MESA New York Bight (MESA-NYB) project from 12 March 1979 to 25 April 1979 (NODC Accession 7900311)

Current meter - direction and other data were collected from FIXED PLATFORMS from 12 March 1979 to 25 April 1979. Data were collected by the National Ocean Service (NOS) in support of the MESA New York Bight (MESA-NYB) 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.

海流计（Current Meter）方向及其他相关数据于1979年3月12日至1979年4月25日期间，通过固定平台采集获取。本次数据由美国国家海洋服务局（National Ocean Service, NOS）为支持MESA纽约湾（MESA New York Bight, MESA-NYB）项目采集。数据已由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准F005——海流计数据（合成值）格式。完整格式说明可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/f005.html查阅。

F005格式适用于通过锚定海流测量仪器获取的海流时间序列数据，主要为安德拉公司（Aanderaa Instruments Inc.）生产的安德拉海流计（Aanderaa current meters）。此类数据采用欧拉海流测量法（Eulerian method），即海流计部署于固定锚泊点位，测量流经传感器的流体运动。每个测站均记录站位坐标、水深及传感器安装深度。数据记录包含指定日期与时间下的海流方向及流速数值。数据值可经过平均处理或滤波，通常以10至15分钟的时间间隔进行上报。此外还可上报其他环境参数，包括：水温、盐度、电导率与透射率；风向与风速；以及优势浪向、浪高与浪周期。同时设有文本字段，用于填写可选备注信息。
