Current direction, temperature, and other data from moored current meter casts in the Gulf of Mexico during the Brine Disposal project, 15 May 1979 - 22 March 1980 (NODC Accession 8000457)

Temperature, salinity, current direction, and other data were collected using moored current meter casts from the EXCELLENCE in the Gulf of Mexico from May 15, 1979 to March 22, 1980. Data were submitted by Texas A&M University as part of the Brine Disposal project. Data has been been processed by NODC to the standard NODC standard F005- Current Meter Data, and F028- Phytoplankton. Full format descriptions are available from NODC homepage at http://www.noaa.nodc.gov

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. A text field is available for optional comments.

The F028 format is used for data from the sampling and analysis of marine phytoplankton. Information on phytoplankton abundance, distribution, and productivity derived from these data support studies of marine populations and ecosystems. Data reported may include: position, date, and time of sampling; bottom depth and sampling depths; volume of water filtered; and concentration of cells, carbon concentration, wet and dry weight, and counts for each species reported. Comments may be relayed in a text record.

1979年5月15日至1980年3月22日期间，科研团队于墨西哥湾海域依托‘EXCELLENCE’号调查船，通过锚泊式海流计布放观测获取了海水温度、盐度、流向等多类海洋环境数据。该数据集由得克萨斯农工大学（Texas A&M University）作为盐水处置项目（Brine Disposal project）的子任务提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将这批数据按照其官方标准格式F005——海流计观测数据——与F028——浮游植物观测数据——完成标准化处理。完整的格式说明可通过美国国家海洋和大气管理局国家海洋数据中心官网（http://www.noaa.nodc.gov）获取。

F005格式适用于锚定式海流测量仪器获取的海流时间序列观测数据，主流观测设备为安德拉海流计（Aanderaa current meters，由Aanderaa仪器公司（Aanderaa Instruments Inc.）制造）。此类数据采用欧拉式海流测量方法：将仪器部署于固定锚泊点位，测量流经传感器的海流。每个测站均记录了站位坐标、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。观测数据通常经过平均化或滤波处理，采样间隔一般为10至15分钟。此外，数据集还可包含其他环境参数，涵盖：海水温度、盐度、电导率与透射率；风向与风速；优势浪向、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。

F028格式用于海洋浮游植物采样与分析所得数据。基于此类数据推导得到的浮游植物丰度、分布及生产力信息，可为海洋种群与生态系统研究提供重要支撑。上报数据可包含：采样站位坐标、采样日期与时间；底床水深与采样层深度；过滤海水体积；以及各类物种的细胞浓度、碳浓度、湿重、干重及个体计数结果。数据集同样可通过文本记录字段添加备注信息。
