Current direction data from moored current meter casts in the Gulf of Mexico during the Brine Disposal project, 16 July 1979 - 02 August 1979 (NODC Accession 8000501)
收藏资源简介:
Current direction data were collected using moored current meter casts in the Gulf of Mexico from July 16, 1979 to August 2, 1979. Data were submitted by Texas A&M University as part of the Brine Disposal and the Outer Continental Shelf - Georges Bank (OCS) 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. A text field is available for optional comments.
本数据集的海流流向数据采集于1979年7月16日至8月2日的墨西哥湾海域,通过锚定海流计开展观测获取。数据由德克萨斯农工大学(Texas A&M University)提交,作为盐水处置及外大陆架-乔治浅滩(Outer Continental Shelf - Georges Bank,简称OCS)项目的一部分。数据由美国国家海洋数据中心(National Oceanographic Data Center,简称NODC)处理为NODC标准海流计数据(F005)格式。完整的锚定海流计布设说明可通过以下网址获取:http://www.nodc.noaa.gov/General/NODC-Archive/f005.html。 F005格式适用于通过锚定海流测量仪器获取的海流时间序列数据,主流设备为安德拉海流计(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(Eulerian method)进行海流测量,即海流计被部署于固定锚点,对流经传感器的流体进行观测。每个测站均会记录站位位置、水深以及传感器布设深度。数据记录包含指定日期与时刻下的海流流向与流速数值。数据值可经过平均处理或滤波处理,通常以10至15分钟的时间间隔进行输出记录。数据集亦可附带其他环境参数,具体包括:海水温度、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,可用于填写可选备注信息。
