Current direction, temperature, and salinity data from moored current meter casts in the Gulf of Mexico during the Brine Disposal project, 1982-02-17 to 1984-08-08 (NODC Accession 8500099)

Current direction, temperature, and salinity data were collected using moored current meter casts in the Gulf of Mexico from February 17, 1982 to August 8, 1984. Data were submitted by Texas A&M University as part of the Brine Disposal project. 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.

1982年2月17日至1984年8月8日，研究团队于墨西哥湾通过锚定海流计布放作业，采集海流方向、海水温度及盐度数据。该数据集由德克萨斯农工大学（Texas A&M University）作为盐水处置项目（Brine Disposal project）的组成部分提交。美国国家海洋数据中心（NODC）将所有数据整理为符合NODC标准的海流计数据（F005）格式。完整的锚定海流计布设说明可通过以下链接获取：http://www.nodc.noaa.gov/General/NODC-Archive/f005.html。
F005格式专用于锚定海流测量仪器获取的海流时间序列数据，其主流选型为安德拉海流计（Aanderaa current meters，由Aanderaa仪器公司（Aanderaa Instruments Inc.）制造）。此类数据采用欧拉法（Eulerian method）开展海流测量：仪器部署于固定锚泊点位，直接测量流经传感器的流体运动参数。每个测站均需记录站位坐标、作业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。数据值可经过平均处理或滤波降噪，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，涵盖：海水温度、盐度、电导率与透射率；风向与风速；以及主浪方向、浪高及浪周期。数据集还设有文本字段，用于填写可选备注信息。
