Temperature profiles from mechanical bathythermograph (MBT) casts from the USS REAPER in the South China Sea in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 04 January 1970 to 06 January 1970 (NODC Accession 7000334)

MBT data were collected from the USS REAPER in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 04 January 1970 to 06 January 1970. 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.MBT数据采集自美国海军“收割者号”（USS REAPER），用于支持海洋数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。数据采集工作由美国海军机会船于1970年1月4日至1月6日完成。该平台配备了专业观测设备并配有操作人员，用于开展气象与海洋状况观测。数据由国家海洋数据中心（National Oceanographic Data Center, NODC）按照其通用深度温度计输出（Universal Bathythermograph Output, UBT）标准格式进行处理。完整的格式说明可从NODC获取，网址为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）仪器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、位置与时间。数据记录由多组温深数值对构成。本文件中的温度数据以每5米的均匀深度间隔进行记录。
