Temperature profiles from mechanical bathythermograph (MBT) casts from the USS MULLANY in the North Pacific Ocean in support of the Integrated Global Ocean Services System (IGOSS) project from 13 July 1954 to 05 March 1955 (NODC Accession 7501245)

MBT data were collected from the USS MULLANY in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the US navy; Ships of Opportunity from 13 July 1954 to 05 March 1955. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html.

The UBT file format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

本MBT数据采集自美国海军MULLANY号舰艇，用于支持综合全球海洋服务系统（Integrated Global Ocean Services System, IGOSS）项目。数据采集时段为1954年7月13日至1955年3月5日，由美国海军机遇观测船（Ships of Opportunity）完成采集。数据由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为符合其标准的通用深度温度计输出（Universal Bathythermograph Output, UBT）格式。完整的格式说明可通过NODC官网的以下链接获取：www.nodc.noaa.gov/General/NODC-Archive/bt.html。
UBT文件格式用于存储通过机械式深度温度计（mechanical bathythermograph, MBT）获取的温深剖面数据。MBT观测的最大探测深度约为285米，因此该类数据仅适用于研究海洋上层的热结构特征。每条观测记录均包含航次信息、观测日期、位置与时间。数据记录由温深值对组成，该文件中的温度数据以5米为固定深度间隔进行记录。
