Current components, pressure, and other data from moored current meters and pressure gauges from FIXED PLATFORMS from the Greenland and Beaufort Seas from 1987-03-28 to 1988-06-01 (NODC Accession 8900129)

Current components, pressure, and other data were collected from moored current meters and pressure gauges from FIXED PLATFORMS in the Greenland and Beaufort Seas. Data were collected by the Pacific Marine Environmental Laboratory (PMEL) from 28 March 1987 to 01 June 1988. Data has been processed by NODC to the standard NODC F005-Current Meter Data and the F017-Pressure Gauge Data formats. Full format and format code descriptions are available at http://www.nodc.noaa.gov/General/NODC-datafmts.html.

This 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.

The F017 format contains time series measurements of seawater pressure from anchored or bottom-mounted sensors. Measurements of variations at depth of seawater pressure provide information on tidal and storm flows, ocean circulation, and other phenomena that cause changes in sea surface elevation or slope and that can be detected from their pressure signature. Position, bottom depth, and gauge depth are reported for each station. The data record comprises values of total pressure at specified date and time. Data values may be subject to averaging or filtering and are typically reported at time intervals of 10-15 minutes. Seawater temperature may also be reported. Comments may be reported in a text record.

本数据集采集了格陵兰海与波弗特海固定平台上锚定海流计及压力计获取的海流分量、海水压力及其他相关数据。数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory, PMEL）于1987年3月28日至1988年6月1日期间采集。数据已由美国国家海洋数据中心（National Oceanographic Data Center, NODC）整理为标准的NODC F005-海流计数据格式与F017-压力计数据格式。完整格式及格式代码说明可查阅网址：http://www.nodc.noaa.gov/General/NODC-datafmts.html。

F015格式用于海流的时间序列测量。此类数据源自锚定海流计，采用欧拉法进行海流观测——即传感器部署于固定点位，测量流经传感器的海流。每个测站均记录站位、海底深度、传感器深度及海流计参数信息。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。海流方向定义为海水流动的去向，以东向与北向为正方向，西向与南向为负方向。数据值可经过平均或滤波处理，通常以10-15分钟为时间间隔进行记录。数据中还可包含海水温度、压力、电导率或盐度信息。可选的注释信息可通过文本记录形式提供。

F017格式用于锚定或海底安装传感器的海水压力时间序列测量。海水不同深度的压力变化测量数据可用于获取潮汐与风暴流、海洋环流及其他引发海面高度或坡度变化的海洋现象信息，此类变化可通过其压力特征信号进行探测。每个测站均记录站位、海底深度及压力计部署深度。数据记录包含指定日期与时刻下的总压力值。数据值可经过平均或滤波处理，通常以10-15分钟为时间间隔进行记录。数据中还可包含海水温度信息。注释信息可通过文本记录形式提供。
