Temperature profiles from mechanical bathythermograph (MBT) casts from the USS BOLD in the Caribbean Sea in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 01 September 1962 to 14 September 1962 (NODC Accession 6200419)

MBT data were collected from the USS BOLD in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 01 September 1962 to 14 September 1962. 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数据采集自美国海军"Bold"号（USS BOLD），用于支撑海洋学数据舰队观测（Fleet Observations of Oceanographic Data，FLOOD）项目。数据采集工作由美国海军及机遇舰船于1962年9月1日至1962年9月14日期间完成。该观测平台配备专业观测设备并配有操作人员，用于开展气象与海况监测。数据已由国家海洋数据中心（National Oceanographic Data Center，NODC）处理为符合其标准的通用海水深度测温仪输出（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海水深度测温仪（Mechanical Bathythermograph，MBT）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。数据记录由温深值对组成，且本文件中的温度数据以5米为固定深度间隔进行记录。
