Temperature profile and other data collected using bottle and CTD casts from the HMAS DERWENT and other platforms from a world-wide distribution during the California Cooperative Fisheries Investigation (CALCOFI) project, 03 August 1904 to 31 December 1964 (NODC Accession 6400000)

Oceanographic Station Data, temperature, and other data were collected using CTD and bottle casts from HMAS DERWENT and other platforms in a world-wide distribution from August 3, 1904 to December 31, 1964. Data were submitted by Australia Navy 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（Oceanographic Station Data）、温度及其他海洋学相关参数，采集于1904年8月3日至1964年12月31日期间，通过CTD（conductivity-temperature-depth，电导率-温度-深度仪）与采水瓶采样（bottle casts），由HMAS DERWENT号及其他作业平台在全球海域完成。数据由澳大利亚海军作为加利福尼亚合作渔业调查（California Cooperative Fisheries Investigation, CALCOFI）项目的一部分提交。美国国家海洋数据中心（National Oceanographic Data Center, NODC）将数据处理为符合NODC标准的《海洋站数据（SD2）》与《通用深度测温仪输出（Universal Bathythermograph Output, UBT）》格式，完整格式说明可访问nodc.noaa.gov查询。

海洋站数据格式包含在离散深度层级记录的物理化学海洋学数据。多数观测采用多瓶式南森采水器（multi-bottle Nansen casts）或其他类型水体采样器完成，仅约5%的少量数据通过电子CTD或STD（salinity-temperature-depth，盐度-温度-深度仪）记录仪获取。尽管CTD/STD数据上报至NODC时采用了与南森采样一致的深度层级，但其处理与存储方式均与南森采样数据完全一致。每个站位均记录航行信息（如舰船、所属国家、研究机构）、站位位置、日期与时间。核心测量参数为温度与盐度，但也可记录溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值。采样时的气象条件（如气温、气压、风力、浪况）亦可被记录，辅助数据则包括水体颜色（福勒-于勒标度，Forel-Ule scale）、水体透明度（塞氏盘深度，Secchi disk depth）及海底深度。通过实测参数可计算得到密度（sigma-t）、声速与动态深度异常值。每个站位既包含实测深度层级的测量数据，也包含内插至一组标准深度层级的数据集。
