Temperature profiles from mechanical bathythermograph (MBT) casts from the USS JACANA in the Coastal Waters of Florida and Gulf of Mexico in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 01 October 1964 to 02 October 1964 (NODC Accession 6400365)

MBT data were collected from the USS JACANA in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 01 October 1964 to 02 October 1964. 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MBT数据采集自JACANA号舰艇，服务于海洋数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。数据由美国海军机遇性船舶于1964年10月1日至1964年10月2日采集。该观测平台配备专业设备与操作人员，用于开展气象与海洋状况观测。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将原始数据按照NODC标准通用深度温度计输出（Universal Bathythermograph Output, UBT）格式进行标准化处理。完整的格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/bt.html查阅获取。

UBT文件格式专用于存储机械式深度温度计（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水体的热结构特征。每条观测记录均包含航次信息、观测日期、位置与时间信息，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5米为均匀深度间隔进行记录。
