Temperature profiles from MBT casts from the SPENCER from Ocean Weather Station C (OWS-C) in the North Atlantic Ocean from 27 January 1973 to 13 February 1973 (NODC Accession 7300211)

Bathythermograph data were collected from SPENCER within a 1-mile radius of Ocean Weather Station C (5245N 03530W) and in transit. Data were collected by the United States Coast Guard from 27 January 1973 to 13 February 1973. 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）数据采集自SPENCER平台，覆盖范围包含海洋气象站C（52°45′N，035°30′W）周边1英里范围内及航行途中。本次数据采集由美国海岸警卫队于1973年1月27日至1973年2月13日期间完成。该平台配备观测设备并配有操作人员，用于开展气象与海洋环境状况观测。所有数据已由国家海洋数据中心（NODC）处理为NODC标准通用温深仪输出（UBT）格式。完整的格式说明可通过NODC官方网址www.nodc.noaa.gov/General/NODC-Archive/bt.html查阅获取。
UBT文件格式用于存储通过机械式温深仪（Mechanical Bathythermograph, MBT）获取的温度-深度剖面数据。机械式温深仪的最大观测深度约为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、位置与观测时间。数据记录由温度-深度数值对构成。该文件内的温度数据以5米的均匀深度间隔进行记录。
