Current meter - direction and other data from FIXED PLATFORMS in support of the MESA New York Bight (MESA-NYB) project from 25 July 1978 to 16 October 1978 (NODC Accession 7900246)

Current meter - direction and other data were collected from FIXED PLATFORMS from 25 July 1978 to 16 October 1978. 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.

本数据集为海流计（Current Meter）观测数据，包含流向及其他相关参数，采集于固定平台，观测时段为1978年7月25日至1978年10月16日。数据由美国国家海洋服务局（National Ocean Service，简称NOS）为支持纽约湾MESA项目（MESA New York Bight，简称MESA-NYB）所采集。数据已由美国国家海洋数据中心（National Oceanographic Data Center，简称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官方网址www.nodc.noaa.gov/General/NODC-Archive/f005.html查询获取。
F005格式适用于锚泊式海流观测仪器获取的海流时间序列数据，核心观测设备为安德拉海流计（Aanderaa Current Meter，由Aanderaa Instruments Inc.制造）。本数据集采用欧拉观测法获取海流数据，即仪器部署于固定锚泊点位，测量流经传感器的海流参数。每个测站均记录测站位置、水深及传感器布设深度。数据记录包含指定日期时间下的流向与流速数值，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。数据集同时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；以及优势浪向、浪高与浪周期。数据中预留文本字段用于填写可选备注信息。
