Current meter - direction and other data from FIXED PLATFORMS in support of the MESA New York Bight (MESA-NYB) project from 25 September 1978 to 11 July 1979 (NODC Accession 7900330)

Current meter - direction and other data were collected from FIXED PLATFORMS from 25 September 1978 to 11 July 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. A text field is available for optional comments.

本数据集采集了1978年9月25日至1979年7月11日期间，固定平台（FIXED PLATFORMS）获取的海流计（current meter）方向及其他相关数据。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。后由国家海洋数据中心（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格式用于锚泊海流测量仪器获取的海流时间序列数据，其主流设备为安德拉海流计（由Aanderaa Instruments Inc.制造）。此类数据采用欧拉法（Eulerian method）进行海流测量，即仪器部署于固定锚泊点位，传感器直接测量流经测点的流体流速与流向。每个测站均会记录站位坐标、水深及传感器布设深度。数据记录包含指定日期与时间下的海流方向及流速数值，数据可经过平均或滤波处理，通常以10至15分钟为间隔进行输出。数据集还可包含其他环境参数，具体包括：水温、盐度、电导率、透射率；风向与风速；以及主波方向、波高与波周期。此外，数据集预留了文本字段用于填写可选备注信息。
