Temperature profiles from mechanical bathythermograph (MBT) casts from the USS GUIDE in the Gulf of Thailand, South China Sean, and the Philippine Sea in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 18 February 1967 to 18 April 1967 (NODC Accession 6700154)

MBT data were collected from the USS GUIDE in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 18 February 1967 to 18 April 1967. 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USS GUIDE号舰艇，用于支撑海洋学数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。数据由美国海军机遇舰船（Ships of Opportunity）于1967年2月18日至1967年4月18日期间采集。该观测平台配备了气象与海况观测设备，并配有专职操作人员。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其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官方网站https://www.nodc.noaa.gov/General/NODC-Archive/bt.html查阅。

UBT文件格式用于记录通过机械式深度温度计（Mechanical Bathythermograph, MBT）采集的温度-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、位置与观测时间。数据记录由多组温度-深度数值对构成，本文件中的温度数据以每5米的均匀深度间隔进行记录。
