Current meter components and other data from FIXED PLATFORMS from the Coastal Waters of S. Alaska from 1986-11-06 to 1987-05-01 (NODC Accession 8700351)

Current meter components data were collected from FIXED PLATFORMS in Coastal Waters of S. Alaska from 06 November 1987 to 01 May 1987. Data were collected by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS). 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.

本数据集的海流计分量数据采集于1987年11月6日至1987年5月1日期间，采集地点为阿拉斯加南部近岸海域的固定观测平台。数据由阿拉斯加大学费尔班克斯分校海洋科学研究所（UAK/IMS）采集。数据已由美国国家海洋数据中心（NODC）处理为符合其F015海流计分量数据标准格式的文件。完整的格式说明可从NODC官网的https://www.nodc.noaa.gov/General/NODC-Archive/f015.html获取。

F015格式存储的是海洋环流的时间序列观测数据。此类数据源自海流计锚系观测，采用欧拉法进行海流测量，即传感器部署于固定点位，监测流经传感器的流体运动。每个测站均会记录测站位置、海底水深、传感器布设深度以及海流计的相关参数特征。数据记录包含指定日期与时刻下的东西向（u）与南北向（v）海流矢量分量数值。海流方向定义为水流流向，以东向与北向为正方向。原始数据可经过平均处理或滤波处理，通常以10至15分钟的时间间隔进行观测记录。数据中还可包含海水温度、压强、电导率或盐度的观测值。数据集附带可选的文本记录用于添加备注信息。
