Temperature profiles from mechanical bathythermograph (MBT) casts from the USS ENHANCE in the North Pacific Ocean in support of the Fleet Observations of Oceanographic Data (FLOOD) project from 28 October 1962 to 01 December 1962 (NODC Accession 6200442)

MBT data were collected from the USS ENHANCE in support of the Fleet Observations of Oceanographic Data (FLOOD) project. Data were collected by US Navy; Ships of Opportunity from 28 October 1962 to 01 December 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.

本数据集的MBT数据由美国海军“增强号”（USS ENHANCE）采集，用于支持海洋学数据舰队观测（Fleet Observations of Oceanographic Data, FLOOD）项目。数据采集时段为1962年10月28日至1962年12月1日，采集方包括美国海军及机会作业船舶（Ships of Opportunity）。该观测平台配备专业设备与人员，可开展气象与海洋状况监测。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将数据处理为符合NODC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www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。

UBT文件格式用于存储由机械式深度温度计（Mechanical Bathythermograph, MBT）采集得到的温度-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、位置与时间参数，数据记录由温度-深度值对组成，文件内的温度数据以5米为固定均匀间隔进行记录。
