Pressure gauge data from NOAA Ship DISCOVERER in the Gulf of Alaska as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 03 March 1976 to 14 May 1976 (NODC Accession 7601905)

Pressure gauge data were collected from the NOAA Ship DISCOVERER in the Gulf of Alaska from 03 March 1976 to 14 May 1976. Data were collected by the Pacific Marine Environmental Laboratory (PMEL) as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F017 Pressure Gauge Data format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f017.html. An analog file for this accession is available from NODC user services.

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.

本数据集为1976年3月3日至1976年5月14日期间，由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）“发现号”科考船在阿拉斯加湾采集的压力计数据。该数据由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory, PMEL）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的组成部分完成采集。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将数据处理为NODC标准F017压力计数据格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f017.html查询，本次存档批次的模拟文件可通过NODC用户服务渠道获取。

F017格式存储锚定式或海底安装式传感器采集的海水压力时序测量数据。海水压力随深度的变化测量结果，可用于获取潮汐与风暴流、海洋环流及其他引发海面高程或坡度变化的现象相关信息，此类变化可通过其压力特征信号被探测到。每个测站均会记录站位位置、海底水深以及测压仪安装深度。数据记录包含指定日期与时刻下的总压力数值。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报告。数据中亦可同步记录海水温度，相关注释可通过文本记录进行补充说明。
