Pressure gauge and other data from fixed platform as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 05 November 1975 to 27 September 1976 (NODC Accession 7601833)

Pressure gauge and other data were collected from a fixed platform from 05 November 1975 to 27 September 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.

1975年11月5日至1976年9月27日，研究人员于固定平台采集了压力表及其他相关数据。该数据集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）的组成部分开展采集工作，随后由美国国家海洋数据中心（National Oceanographic Data Center，NODC）按照NODC标准F017压力表数据格式完成规范化处理。完整的格式说明文档可通过NODC官方网址www.nodc.noaa.gov/General/NODC-Archive/f017.html查询获取，本次入库数据集的模拟格式文件可通过NODC用户服务渠道获取。

F017格式用于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。对海水压力随深度变化的测量，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海洋现象的相关信息，此类变化可通过其压力特征信号被检测识别。每个测站均会记录站位坐标、海底水深及压力表埋设深度。数据记录包含指定日期与时刻的总压力数值，数据值可经过平均化或滤波处理，通常以10至15分钟的时间间隔进行上报。数据中亦可附带海水温度测量值，相关注释说明可通过文本记录字段进行附加。
