Temperature profiles from mechanical bathythermograph (MBT) casts from the USS GUIDE in the South China Sea in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 07 August 1967 to 16 August 1967 (NODC Accession 6700424)

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 07 August 1967 to 16 August 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数据采集自美国海军GUIDE号舰船，用于支持海洋数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。该数据由美国海军机遇观测舰船于1967年8月7日至1967年8月16日采集。观测平台配备专用设备并配有操作人员，用于开展气象与海洋状况观测。数据经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准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：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水体的热结构特征。每条观测记录均附带航次信息、观测日期、位置与时间。数据记录由温度-深度值对构成，本文件中的温度数据以5米为等间距深度间隔进行记录。
