Temperature profiles from mechanical bathythermograph (MBT) casts from the USS PRIME in the South China Sea in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 03 February 1970 to 18 March 1970 (NODC Accession 7000378)

MBT data were collected from the USS PRIME in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 03 February 1970 to 18 March 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.本数据集的机械式深度温度计（Mechanical Bathythermograph, MBT）数据采集自美国海军“PRIME”号（USS PRIME）舰艇，用于支持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观测船于1970年2月3日至1970年3月18日期间采集。该观测平台配备了气象与海况观测设备并配有专业操作人员。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将原始数据处理为符合NODC标准的通用深度温度计输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可通过NODC官网获取，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（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。每份观测记录均包含航次信息、观测日期、位置及时间。数据记录由温度-深度值对构成，本文件中的温度数据以5米的均匀深度间隔进行存储。
