Temperature profiles from MBT casts from the CASCO from Ocean Weather Station B (OWS-B) in the North Atlantic Ocean from 30 December 1967 to 22 January 1968 (NODC Accession 6700676)

Bathythermograph data were collected from the CASCO within a 1-mile radius of Ocean Weather Station B (5630N 05100W) and in transit. Data were collected by the United States Coast Guard from 30 December 1967 to 22 January 1968. 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.本数据集为海水温深计（Bathythermograph）观测数据，采集于海洋气象站B（56°30′N，51°00′W）周边1英里范围及航行途中的CASCO平台。该数据由美国海岸警卫队于1967年12月30日至1968年1月22日期间采集。该平台配备观测设备并配有专业人员，用于开展气象与海况监测。数据已由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为符合其标准的通用温深计输出（Universal Bathythermograph Output, UBT）格式。完整的格式说明可通过NODC官网的https://www.nodc.noaa.gov/General/NODC-Archive/bt.html 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。机械式温深仪观测的最大深度约为285米，因此其数据仅适用于研究海洋上层的热结构。每条观测记录均包含航行信息、观测日期、位置及时间，数据记录由多组温度-深度数值对构成。该文件中的温度数据以5米为固定深度间隔进行记录。
