Temperature and salinity profiles from CTD casts from NOAA Ship DISCOVERER and other platforms from the North Pacific Ocean and other locations from 1968-04-01 to 1993-06-26 (NODC Accession 9400182)

CTD data were collected from NOAA Ship DISCOVERER and other platforms from the North Pacific Ocean and other locations. Data were collected from 01 April 1968 to 26 June 1993. 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.

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CTD（电导率-温度-深度，conductivity-temperature-depth）数据采集自NOAA探索者号（NOAA Ship DISCOVERER）及其他观测平台，覆盖北太平洋及其他海域。数据采集时段为1968年4月1日至1993年6月26日。所有数据均已由美国国家海洋数据中心（NODC）处理为符合NODC标准的F022高分辨率CTD/STD输出格式。完整格式说明可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/f022.html获取。
F022格式包含利用CTD（电导率-温度-深度，conductivity-temperature-depth）与STD（盐度-温度-深度，salinity-temperature-depth）仪器采集的高分辨率海洋观测数据。此类电子设备在海洋中布放并升降的过程中，可输出温度、盐度及其他观测参数的近乎连续的剖面数据。数据值可经平均、滤波处理，或通过插值方法得到，也可按照精细至1米的深度间隔进行上报。每个测站均会记录航次与仪器相关信息、站位坐标、观测日期、时间及采样间隔。观测作业时的现场环境数据（气象状况与海表状态）亦可一并上报。数据记录包含温度、盐度或电导率、密度（计算得到的σ-t），以及指定深度或压力层级下的溶解氧或透射率数据（若有）。数据可按照等间距或不等间距的深度/压力间隔进行上报。此外还可附带文本记录用于填写相关备注。
