Current meter data from moored current meter casts in the Bering Sea and Gulf of Alaska as part of the Fisheries-Oceanography Cooperative Investigations (FOCI) project from 1991-04-04 to 1992-09-23 (NODC Accession 9400111)

Current meter data were collected using moored current meter casts in the Bering Sea and Gulf of Alaska from April 4, 1991 to September 23, 1992. Data were submitted by Pacific Marine Environmental Laboratory (PMEL) as part of the Fisheries-Oceanography Cooperative Investigations (FOCI) 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.本数据集的海流计数据采集于1991年4月4日至1992年9月23日期间，通过在白令海（Bering Sea）与阿拉斯加湾（Gulf of Alaska）开展的锚定海流计观测作业获取。数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory，PMEL）作为渔业与海洋学合作调查（Fisheries-Oceanography Cooperative Investigations，FOCI）项目的组成部分提交。数据已由国家海洋数据中心（National Oceanographic Data Center，NODC）处理为NODC标准海流计数据（F015）格式。完整的锚定海流计布设说明可通过以下链接获取：http://www.nodc.noaa.gov/General/NODC-Archive/f015.html。 F015格式用于海洋环流的时间序列测量。此类数据源自锚定海流计观测，采用欧拉法（Eulerian method）进行海流测量，即海流计布设于固定点位，通过传感器采集流经测点的水流参数。每个测站均会记录站位位置、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）与北-南向（v）海流矢量分量数值。海流方向定义为水流的流向，其中正东、正北为正方向，正西、正南为负方向。数据值可经过平均或滤波处理，通常以10至15分钟的时间间隔进行记录。数据集还可包含水温、压力、电导率或盐度等辅助观测数据，同时提供可选的文本记录用于附加注释说明。
