Temperature profiles from MBT casts from the MACKINAC from Ocean Weather Station C (OWS-C) in the North Atlantic Ocean from 02 September 1964 to 29 September 1964 (NODC Accession 6400031)

Bathythermograph data were collected from the MACKINAC within a 1-mile radius of Ocean Weather Station C (5245N 0350W) and in transit. Data were collected by the United States Coast Guard from 02 September 1964 to 29 September 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.

温深仪（Bathythermograph）观测数据采集自麦基诺号（MACKINAC），覆盖海洋气象站C（坐标：52°45′N，35°00′W）周边1英里海域及航行途中。美国海岸警卫队于1964年9月2日至9月29日期间完成数据采集。该观测平台配备专业设备并配有操作人员，用于开展气象与海洋状况观测。数据由美国国家海洋数据中心（National Oceanographic Data Center，NODC）按照其标准通用温深仪输出（Universal Bathythermograph Output，UBT）格式进行处理。完整格式说明可通过NODC官网的www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。
UBT文件格式用于存储通过机械温深仪（Mechanical Bathythermograph，MBT）获取的温度-深度剖面数据。机械温深仪的最大观测深度约为285米，因此其数据仅适用于研究海洋上层的热结构。每份观测记录均包含航次信息、观测日期、位置及时间，数据记录由多组温度-深度值对组成，且该文件中的温度数据以5米为等深度间隔进行记录。
