Temperature profile and other data collected using bottle and CTD casts from the A. AGASSIZ and other platforms from the Coastal Waters of California during the California Cooperative Fisheries Investigation (CALCOFI) project, 10 July 1969 to 26 October 1988 (NODC Accession 9000096)

Oceanographic Station Data, temperature, and other data were collected using CTD and bottle casts from A. AGASSIZ and other platforms from the Coastal Waters of California from July 10, 1969 to October 26, 1988. Data were submitted by Scripps Institution of Oceanography as part of the California Cooperative Fisheries Investigation (CALCOFI) project. Data were processed by NODC to the NODC standard Oceanographic Station Data (SD2) and the Universal Bathythermograph Output (UBT) formats. Full format descriptions are available at nodc.noaa.gov/.

The Oceanographic Station Data format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity , but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.

本数据集涵盖海洋站数据、温度及其他相关海洋学参数，采集于1969年7月10日至1988年10月26日期间，依托阿加西号（A. AGASSIZ）及其他科考平台，于加利福尼亚近岸海域通过温盐深仪（Conductivity-Temperature-Depth, CTD）和采水瓶采样获取。数据由斯克里普斯海洋研究所提交，作为加州合作渔业调查（California Cooperative Fisheries Investigation, CALCOFI）项目的组成部分。美国国家海洋数据中心（National Oceanographic Data Center, NODC）将原始数据处理为符合标准的海洋站数据格式（SD2）与通用深度测温仪输出格式（Universal Bathythermograph Output, UBT），完整格式说明可访问nodc.noaa.gov查询。

海洋站数据格式包含离散深度层级下记录的物理化学海洋学观测数据。多数观测采用多瓶南森采水器或其他类型水体采样器完成，仅约5%的观测数据通过电子温盐深仪（CTD）或盐温深仪（Salinity-Temperature-Depth, STD）记录仪获取。不过，所有提交至NODC的CTD/STD数据均统一匹配至南森采水采样的深度层级，并与南森采样数据采用相同流程完成处理与存储。每个测站均记录有航次信息（如科考船、所属国家及机构）、站位坐标、观测日期与时间。核心测量参数为温度与盐度，同时可能包含溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值等数据。采样时的气象条件（如气温、气压、风向风速、海浪情况）也可能被记录，此外还可能包含水体颜色（弗洛尔-于勒色度标度，Forel-Ule scale）、水体透明度（塞氏盘深度，Secchi disk depth）及水深等辅助数据。密度（σ_t）、声速及动态深度异常值由实测参数计算得到。每个测站既包含观测深度层级下的实测数据，也包含经插值得到的标准深度层级对应数据值。
