Current direction, temperature, and salinity data from moored current meter casts in the Gulf of Mexico during the Brine Disposal project, 1983-08-31 to 1984-10-01 (NODC Accession 8500021)

Current direction, temperature, and salinity data were collected using moored current meter casts in the Gulf of Mexico from August 31, 1983 to October 1, 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.

1983年8月31日至1984年10月1日，研究团队于墨西哥湾通过锚定海流计观测采集得到海流方向、水温及盐度数据。本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（National Oceanographic Data Center, NODC）已将数据处理为NODC标准锚定海流计数据（F005）格式。完整的锚定海流计布放说明可通过链接http://www.nodc.noaa.gov/General/NODC-Archive/f005.html查阅。
F005格式适用于锚定海流测量仪器获取的海流时间序列观测，其主流仪器为安德拉海流计（Aanderaa current meters，由安德拉仪器公司（Aanderaa Instruments Inc.）制造）。此类数据采用欧拉法进行海流测量，即仪器布设于固定锚定点位，实时测量流经传感器的流体运动状态。每个观测站位均需记录站位位置、水体深度及传感器布设深度。数据记录包含指定日期与时刻下的海流方向与流速数值。数据值可经过平均或滤波处理，通常以10至15分钟的时间间隔进行输出。数据集还可附带其他环境参数，具体包括：水温、盐度、电导率、透射率；风向与风速；以及主浪方向、浪高与浪周期。数据集预留文本字段用于填写可选备注信息。
