Current direction and temperature data from moored current meter casts in the Gulf of Mexico from 1980-03-24 to 1980-06-16 (NCEI Accession 8200220)

Current direction and temperature data were collected using moored current meter casts in the Gulf of Mexico from March 24, 1980 to June 16, 1980. Data were submitted by National Ocean Service (NOS). Data were processed by NODC to the NODC standard Current Meter Data (F005) format. Full current meter moorings descriptions are available at http://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.

1980年3月24日至1980年6月16日期间，研究团队于墨西哥湾采用锚定海流计布放作业采集海流方向与温度数据。该数据集由美国国家海洋服务局（National Ocean Service, NOS）提交，经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为标准海流计数据格式（F005）。完整的锚定海流计布放方案说明可访问以下链接：http://www.nodc.noaa.gov/General/NODC-Archive/f005.html。

F005格式用于存储由锚定海流测量仪器获取的海流时间序列数据，此类仪器以安德拉海流计（Aanderaa Instruments Inc.制造）为主。该类数据采用海流测量的欧拉法（Eulerian method）获取，即海流计布设于固定锚点，测量流经传感器的海流。每个测站均会记录测站位置、水深及传感器布设深度。数据记录包含指定日期与时间下的海流方向与流速数值。数据数值可经过平均化或滤波处理，通常以10至15分钟为时间间隔进行记录。数据集亦可包含其他环境参数，具体包括：水温、盐度、电导率与透射率；风向与风速；以及主波方向、波高与波周期。数据集预留文本字段以供填写可选备注信息。
