Temperature profiles from mechanical bathythermograph (MBT) casts from the USS CONSTANT in the South China and the Philippine Seas in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 27 June 1966 to 16 July 1966 (NODC Accession 6600107)

MBT data were collected from the USS CONSTANT in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected in the South China and the Philippine Seas by US Navy; Ships of Opportunity from 27 June 1966 to 16 July 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.本MBT数据采集自“康斯坦特号”（USS CONSTANT）舰艇，用于支撑海洋学数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。数据由美国海军及机会舰船（Ships of Opportunity）于1966年6月27日至7月16日在南海与菲律宾海域采集。该观测平台配备专用观测设备并配备专业人员，可开展气象与海洋状况观测。数据由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照其通用温深仪输出（Universal Bathythermograph Output, UBT）标准格式进行处理。完整的格式说明可从美国国家海洋数据中心官网获取，网址为www.nodc.noaa.gov/General/NODC-Archive/bt.html。 通用温深仪输出（UBT）文件格式用于存储通过机械温深仪（Mechanical Bathythermograph, MBT）采集的温度-深度剖面数据。机械温深仪的最大观测深度约为285米，因此该类数据仅适用于研究海洋上层的热结构。每条观测记录均包含航次信息、观测日期、观测位置与观测时间。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。
