Temperature profiles from mechanical bathythermograph (MBT) casts from the USS STURDY in the North Atlantic Ocean in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 25 January 1962 to 23 March 1962 (NODC Accession 6200095)

MBT data were collected from the USS STURDY in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 25 January 1962 to 23 March 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.

MBT数据采集自美国海军“坚毅号”（USS STURDY），以支持海洋学数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。该数据由美国海军机遇舰船于1962年1月25日至1962年3月23日采集。观测平台配备了气象与海况观测设备并配有操作人员。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将数据处理为符合其标准的通用探海仪输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。

UBT文件格式用于存储通过机械式探海仪（mechanical bathythermograph, 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，因此其数据仅可用于研究海洋上层的热结构。每条观测记录均包含航次信息、观测日期、位置与时间。数据记录由若干温度-深度值对构成。本文件中的温度数据以5米为均匀深度间隔进行记录。
