Temperature profiles from mechanical bathythermograph (MBT) casts from the USS WARBLER in the South China Sea in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 23 February 1966 to 26 February 1966 (NODC Accession 6600597)

MBT data were collected from the USS WARBLER in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected in the South China Sea by US Navy; Ships of Opportunity from 23 February 1966 to 26 February 1966. 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"WARBLER"号（USS WARBLER），用于支撑海洋数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。该数据由美国海军借助临时任务舰船于1966年2月23日至2月26日在南海采集。作业平台配备专业观测设备与操作人员，可开展气象与海洋状况监测。美国国家海洋数据中心（National Oceanographic Data Center, NODC）将数据处理为符合其标准的通用温深仪输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可通过美国国家海洋数据中心官网（www.nodc.noaa.gov/General/NODC-Archive/bt.html）获取。

UBT文件格式用于存储通过机械温深仪（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。数据记录由多组温度-深度值对构成，本文件中的温度数据以5米为均匀深度间隔进行记录。
