Temperature profiles from MBT casts from the MCCULLOCH from Ocean Weather Station D (OWS-D), E (OWS-E), and H (OWS-H) in the North Atlantic Ocean from 28 April 1968 to 31 May 1968 (NODC Accession 6800493)

Bathythermograph data were collected from the MCCULLOCH within a 1-mile radius of Ocean Weather Station D (4400N 04100W), E (3500N 04800W), H (3800N 07100W), and in transit. Data were collected by the United States Coast Guard from 28 April 1968 to 31 May 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.

海水温度记录仪（Bathythermograph）数据采集自麦卡洛克号（MCCULLOCH），采集范围覆盖海洋气象站D（44°00′N 041°00′W）、E（35°00′N 048°00′W）、H（38°00′N 071°00′W）周边1英里区域及航行途中。美国海岸警卫队于1968年4月28日至1968年5月31日完成该批数据的采集工作。该观测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。数据由美国国家海洋数据中心（NODC）按照NODC标准通用海水温度记录仪输出格式（Universal Bathythermograph Output, UBT）进行标准化处理。完整的格式说明可通过NODC官网获取，网址为www.nodc.noaa.gov/General/NODC-Archive/bt.html。

UBT文件格式用于存储通过机械式海水温度记录仪（Mechanical Bathythermograph, MBT）获取的温深剖面数据。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行信息、观测日期、位置与时间。数据记录由多组温深数值对构成，且该文件中的温度数据以每5米的均匀深度间隔进行记录。
