Temperature profile and other data collected using CTD casts in the TOGA Area - Pacific Ocean from NOAA Ship RESEARCHER from 1984-04-09 to 1984-11-05 (NODC Accession 8800072)

Temperature profile and other data were collected using CTD casts from NOAA Ship RESEARCHER in the TOGA Area - Pacific Ocean from 09 April 1984 to 05 November 1984. Data were collected by the Pacific Marine Environmental Laboratory with support from the Equatorial Pacific Ocean Climate Studies (EPOCS) project. Data were processed by NODC to the NODC standard High-Resolution STD/CTD Data (F022) 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.

1984年4月9日至11月5日，美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）“探索者号”（RESEARCHER）科考船于太平洋热带海洋全球大气（Tropical Ocean-Global Atmosphere，TOGA）研究区域开展作业，通过CTD（conductivity-temperature-depth，电导率-温度-深度）剖面测量获取温度剖面及其他相关数据。该数据由太平洋海洋环境实验室采集，并得到赤道太平洋海洋气候研究（Equatorial Pacific Ocean Climate Studies，EPOCS）项目的支持。美国国家海洋数据中心（National Oceanographic Data Center，NODC）将这批数据处理为NODC标准高分辨率STD/CTD数据（F022）格式。完整格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/f022.html查阅。

F022格式涵盖通过CTD与STD（salinity-temperature-depth，盐度-温度-深度）仪器采集的高分辨率数据。此类电子设备在海洋中布放并升降的过程中，可近乎连续地输出温度、盐度及其他参数的剖面数据。数据值可经过平均、滤波或插值处理，可按精细至1米的深度间隔进行记录。每个测站均会记录航次与仪器信息、站位坐标、日期、时间及采样间隔。测站作业时刻的环境数据（气象状况与海表状态）亦可同步记录。数据记录包含指定深度或压力层位处的温度、盐度或电导率、密度（计算得到的σ-t）数据，以及可能附带的溶解氧或透射率数据。数据可按等间距或不等间距的深度/压力间隔进行上报。此外还提供文本记录用于填写备注信息。
