Current meter data from moored current meter casts in the Coastal Waters of Florida as part of the Florida Straits Physical Oceanography (FSPO) project from 1990-11-23 to 1991-08-19 (NCEI Accession 9200237)

Current meter data were collected using moored current meter casts in the Coastal Waters of Florida from November 23, 1990 to August 19, 1991. Data were submitted by Science Applications, INC. - Raileigh NC as part of the Florida Straits Physical Oceanography (FSPO) project. Data were processed by NODC to the NODC standard Current Meter Data (F015) format. Full current meter moorings descriptions are available at http://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.

本数据集的海流计观测数据采集于1990年11月23日至1991年8月19日，采用锚泊海流计投放观测方式，在佛罗里达近岸海域完成。该数据由位于北卡罗来纳州Raileigh的科学应用公司（Science Applications, INC.）作为佛罗里达海峡物理海洋学（Florida Straits Physical Oceanography, FSPO）项目的组成部分提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将所有数据处理为NODC标准海流计数据（Current Meter Data, F015）格式。完整的锚泊海流计部署说明可通过以下链接获取：http://www.nodc.noaa.gov/General/NODC-Archive/f015.html。

F015格式专用于海洋环流的时间序列观测。此类数据均来自锚泊海流计，采用欧拉法（Eulerian method）开展海流测量，即：将海流计固定部署于测点，测量流经传感器的水流运动。每个观测站位均需记录其地理位置、海底水深、传感器布设深度以及海流计的参数特性。数据记录包含指定日期与时刻下的东西向（east-west, u）与南北向（north-south, v）海流矢量分量数值。海流方向定义为水流的流向，其中东向与北向为正方向，西向与南向为负方向。数据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记录上报。观测数据还可附带记录海水温度、压力、电导率或盐度等辅助参数。此外还设有文本记录字段，用于填写可选备注信息。
