Physical, meteorological, and other data from surface sensors and CTD casts from the NOAA Ship DISCOVERER and other platforms as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 30 January 1981 to 02 June 1981 (NODC Accession 8300002)

Physical, meteorological, and other data were collected from surface sensors and CTD casts from the NOAA Ship DISCOVERER and other platforms. Data were collected by the Pacific Marine Environmental Laboratory (PMEL) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 30 January 1981 to 02 June 1981. Data were processed by NODC to the NODC standard F022 High-Resolution CTD/STD Output Format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f022.html. An analog file for this accession is available from NODC user services.

The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

本数据集涵盖物理、气象及其他相关数据，采集自美国国家海洋和大气管理局（NOAA）“发现者号”（DISCOVERER）科考船搭载的水面传感器及CTD（Conductivity-Temperature-Depth，电导率-温度-深度）剖面测量作业，同时整合了其他平台的同类数据。数据由太平洋海洋环境实验室（PMEL）作为外大陆架环境评估计划（OCSEAP）的一部分，于1981年1月30日至1981年6月2日期间采集完成。后续由国家海洋数据中心（NODC）按照NODC标准F022高分辨率CTD/STD输出格式进行标准化处理。完整的格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f022.html获取，本数据集对应的模拟文件可通过NODC用户服务渠道获取。

F022格式存储了采用CTD（Conductivity-Temperature-Depth，电导率-温度-深度）与STD（Salinity-Temperature-Depth，盐度-温度-深度）仪器采集的高分辨率数据。当此类电子设备在海洋中布放并回收时，可连续采集温度、盐度及其他参数的剖面数据。数据值可经过平均、滤波处理或通过插值方法生成，其深度采样间隔最小可达1米。每个测站均记录有航次与仪器信息、站位坐标、日期、时间及采样间隔。此外，还可记录剖面测量作业时的环境数据，包括气象与海面状态信息。数据集记录包含指定深度或压力层级下的温度、盐度（或电导率）、密度（计算得到的sigma-t，即密度距平）数据，部分数据集还包含溶解氧或透射率参数。数据可按等间距或不等间距的深度/压力间隔进行存储。此外，数据集附带文本记录以容纳相关注释信息。
