Current and other data from fixed platforms as part of the International Decade of Ocean Exploration / International Ocean Studies / First Dynamic Response and Kinematics Experiment in the Drake Passage (IDOE/ISOS/FDRAKE) from 1979-01-13 to 1980-02-01 (NODC Accession 8700085)

Current and other data were collected from fixed platforms from 13 January 1979 to 01 February 1980. Data were collected by Oregon State University (OSU) as part of the International Decade of Ocean Exploration / International Ocean Studies / First Dynamic Response and Kinematics Experiment in the Drake Passage (IDOE/ISOS/FDRAKE). Data were processed by NODC to the NODC standard F015 Current Meter Components format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f015.html.

The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments.

1979年1月13日至1980年2月1日期间，海流及相关数据均通过固定观测平台采集。该数据集由俄勒冈州立大学（Oregon State University, OSU）作为“国际海洋勘探十年计划/国际海洋研究/德雷克海峡首次动力响应与运动学实验（International Decade of Ocean Exploration / International Ocean Studies / First Dynamic Response and Kinematics Experiment in the Drake Passage, IDOE/ISOS/FDRAKE）”的子项目完成采集。后续由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照其标准F015海流计分量格式完成数据处理。完整的格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/f015.html查询获取。

F015格式专用于海洋环流的时间序列测量，数据来源于海流计锚系站点，采用欧拉式海流测量方法：将传感器布设于固定点位，测量流经传感器的水流参数。每个测站均会记录站位坐标、海底水深、传感器布设深度以及海流计的设备参数。数据记录包含指定日期与时刻下的东-西向（u）和北-南向（v）海流矢量分量。海流方向定义为水流流向，正东、正北为正方向，正西、正南为负方向。原始数据通常经过平均或滤波处理，采样间隔一般为10至15分钟。数据集还可包含水温、压强、电导率或盐度等辅助观测参数。此外，预留了文本记录字段用于附加备注信息。
