Current direction, temperature, and salinity data from moored current meter casts in the Gulf of Mexico during the Brine Disposal project, 1981-02-07 to 1982-06-01 (NODC Accession 8300040)

Current direction, temperature, and salinity data were collected using moored current meter casts in the Gulf of Mexico from February 7, 1981 to June 1, 1982. 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.

1981年2月7日至1982年6月1日，研究人员在墨西哥湾通过锚定海流计锚系观测，采集得到海流流向、水温及盐度数据。该数据集由得克萨斯农工大学（Texas A&M University）作为盐水处置（Brine Disposal）项目的组成部分提交。美国国家海洋数据中心（National Oceanographic Data Center，简称NODC）将所有数据处理为NODC标准海流计数据（F005）格式。完整的锚定海流计锚系说明可通过以下网址获取：http://www.nodc.noaa.gov/General/NODC-Archive/f005.html。

F005格式适用于记录锚定海流测量仪器获取的海流时间序列数据，其主流搭载设备为安德拉仪器公司（Aanderaa Instruments Inc.）生产的安德拉海流计。此类数据采用欧拉法（Eulerian method）开展海流测量，即将仪器部署于固定锚系点位，测量流经传感器的海流参数。每个测站均需上报点位坐标、水深及传感器布设深度。数据记录包含指定日期与时刻下的海流流向与流速数值，数据可经平均或滤波处理，通常以10至15分钟的时间间隔进行上报。数据集还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；主波向、波高及波周期。此外，预留了文本字段用于填写可选备注信息。
