Temperature profiles from mechanical bathythermograph (MBT) casts from the USS GUIDE in the North Pacific Ocean in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 07 April 1963 to 04 May 1963 (NODC Accession 6300289)

MBT data were collected from the USS GUIDE in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 07 April 1963 to 04 May 1963. The platform was equipped and staffed to observe weather and sea conditions. 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.

机械式深水温度计（Mechanical Bathythermograph, MBT）数据采集自“GUIDE”号舰艇，用于支持海洋学数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。该数据集由美国海军及志愿观测船（Ships of Opportunity）于1963年4月7日至1963年5月4日期间采集。该观测平台配备专业观测设备并配有操作人员，用于开展气象与海洋环境状况监测。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将该数据处理为符合其标准的通用深水温度计输出（Universal Bathythermograph Output, UBT）格式。完整的格式说明可通过NODC官方网址www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。
UBT文件格式用于存储通过机械式深水温度计（MBT）采集得到的温度-深度剖面数据。MBT观测的最大探测深度约为285米，因此该数据集仅可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、位置及时间参数。单条数据记录由多组温度-深度数值对组成。该文件中的温度数据以均匀的5米深度间隔进行记录。
