Current meter components and other data from FIXED PLATFORMS from Yellow Sea (Hwang Hai) from 10 January 1986 to 30 June 1986 (NODC Accession 8800190)

Current meter components data were collected from FIXED PLATFORMS in the Yellow Sea (Hwang Hai) from 10 January 1986 to 30 June 1986. Data were collected by Florida State University (FSU) and was funded under NSF grant OCE-8500181. 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 contains time series measurements of ocean currents. These data are obtained from current meter moorings and represent the 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 includes 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. 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.

本数据集为海流计组件观测数据，观测时段为1986年1月10日至1986年6月30日，观测区域为黄海（Hwang Hai）的固定平台海域。数据由佛罗里达州立大学（Florida State University, FSU）采集，由美国国家科学基金会（National Science Foundation, NSF）OCE-8500181号项目资助。数据经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理，采用NODC标准F015海流计组件格式进行归档存储。完整格式说明可通过NODC官方网址获取：www.nodc.noaa.gov/General/NODC-Archive/f015.html。

F015格式用于存储海流时间序列观测数据，其数据来源于海流计锚系观测，采用海流测量的欧拉法（Eulerian method）——即海流计布设于固定点位，通过传感器采集流经该点的水流数据。每个测站均会记录其位置、海底水深、传感器布设深度以及海流计的相关参数。数据记录包含指定日期与时刻下的东西向（u）与南北向（v）海流矢量分量。海流流向定义为水流的运动方向，以正东与正北为正方向。数据值通常经过平均处理或滤波处理，常规采样时间间隔为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，同时提供文本记录用于填写可选备注信息。
