Current meter - direction and other data from FIXED PLATFORMS in support of the Brine Disposal project from 01 September 1978 to 30 September 1978 (NODC Accession 7900007)

Current meter - direction and other data were collected from FIXED PLATFORMS from 01 September 1978 to 30 September 1978. Data were collected by the National Data Buoy Center (NDBC) in support of the Brine Disposal project. Data were processed by NODC to the NODC standard F005 - Current Meter Data (Resultants) format. Full format description is available from NODC at 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.

本数据集采集了1978年9月1日至1978年9月30日期间，由固定平台（FIXED PLATFORMS）获取的海流计（current meter）方向及其他相关数据。数据由美国国家数据浮标中心（National Data Buoy Center, NDBC）为支持盐水处置项目（Brine Disposal project）采集，后由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照其制定的F005标准——海流计数据（合成值，Current Meter Data (Resultants)）格式完成处理。完整的格式说明文档可通过NODC官方网址www.nodc.noaa.gov/General/NODC-Archive/f005.html获取。

F005格式用于记录系泊式海流测量仪器获取的海流时间序列数据，此类仪器以安德里亚仪器公司（Aanderaa Instruments Inc.）生产的安德里亚海流计（Aanderaa current meters）为主。本数据集采用欧拉法（Eulerian method）进行海流测量，即海流计被部署于固定系泊点位，通过传感器直接测量流经自身的流体流速与流向。每个测站均会记录其地理位置、作业水深以及传感器埋设深度。数据记录包含指定日期与时刻下的海流方向及流速数值，原始数据通常会经过平均或滤波处理，记录时间间隔一般为10至15分钟。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；以及主波方向、波高与波周期。此外，数据集预留了文本字段以填写可选备注信息。
