Temperature profiles from mechanical bathythermograph (MBT) casts from the USS FIDELITY in the Coastal Waters of Florida in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 28 November 1961 to 01 December 1961 (NODC Accession 6100312)

MBT data were collected from the USS FIDELITY in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 28 November 1961 to 01 December 1961. 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.

机械温深仪（Mechanical Bathythermograph, MBT）数据采集自美国海军"忠诚"号舰艇，用于支持海洋数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。该数据由美国海军依托机会舰船（Ships of Opportunity），于1961年11月28日至1961年12月1日期间采集。作业平台配备专用观测设备并配有操作人员，用于开展气象与海洋环境状况观测。数据经国家海洋数据中心（National Oceanographic Data Center, NODC）处理，符合其标准的通用温深仪输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可从NODC官网www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。
UBT文件格式用于记录通过MBT获取的温度-深度剖面数据。MBT观测的最大探测深度约为285米，因此其数据仅适用于研究海洋上层水体的热结构特征。每条观测记录均包含航次信息、观测日期、站位与观测时间。数据记录由多组温度-深度值对组成，本文件中的温度数据以均匀的5米深度间隔进行存储。
