Temperature profiles from MBT casts from the CASTLE ROCK from Ocean Weather Station C (OWS-C) in the North Atlantic Ocean 01 July 1964 to 06 August 1964 (NODC Accession 6400054)

Bathythermograph data were collected from the CASTLE ROCK 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 01 July 1964 to 06 August 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）数据由CASTLE ROCK号平台采集，采集范围覆盖C号海洋气象站（52°45′N 035°00′W）周边1英里海域及航行途中。该数据由美国海岸警卫队于1964年7月1日至1964年8月6日完成采集。该平台配备专业观测设备并配有操作人员，用于开展气象与海洋状况监测。数据由国家海洋数据中心（NODC）按照通用温深仪输出（Universal Bathythermograph Output, UBT）标准格式进行处理。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温深仪（Mechanical Bathythermograph, MBT）采集的温度-深度剖面数据。MBT观测的最大深度约为285米，因此该类数据仅可用于研究海洋上层的热结构特征。每份观测记录均包含航次信息、观测日期、位置与时间。数据记录由多组温度-深度值对构成。该文件中的温度数据以5米为等间距深度间隔进行记录。
