NODC Standard Format Coastal Current Meter (Resultants) (F005) Data (1972-1993) (NODC Accession 0084999)

This data set contains time series measurements of subsurface 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 contains 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.

本数据集包含采用锚定海流测量仪器获取的水下海流时序观测数据，核心测量设备为Aanderaa海流计（Aanderaa current meters），由Aanderaa仪器公司（Aanderaa Instruments, Inc.）制造。本数据集采用欧拉法（Eulerian method）进行海流测量，即仪器部署于固定锚泊点位，直接测量流经传感器的海流。每个测站均会记录其位置、水深与传感器布设深度，数据记录包含指定日期时间下的海流方向与流速数值。数据值可经过平均处理或滤波处理，通常以10至15分钟为时间间隔进行上报。数据集亦可附带其他环境参数，具体包括：水温、盐度、电导率与透射率；风向与风速；以及优势浪的方向、波高与周期。数据集预留文本字段，用于填写可选备注信息。
