Temperature profiles from MBT casts from the MCCULLOCH from Ocean Weather Station D (OWS-D) in the North Atlantic Ocean from 17 September 1966 to 17 October 1966 (NODC Accession 6600056)

Bathythermograph data were collected from the MCCULLOCH within a 1-mile radius of Ocean Weather Station D (4400N 0410W) and in transit. Data were collected by the United States Coast Guard from 17 September 1966 to 17 October 1966. 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，采集自"MCCULLOCH"号船只，观测范围覆盖海洋气象站D（44°00′N 041°00′W）周边1英里海域及航行途中。数据由美国海岸警卫队于1966年9月17日至1966年10月17日期间采集。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。数据经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理，转换为符合其标准的通用温深计输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可通过NODC官网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计（Mechanical Bathythermograph, MBT）获取的温度-深度剖面数据。机械式温深计观测的最大深度约为285米，因此该类数据仅适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、位置与时间。数据记录由温度-深度值对组成，本文件中的温度数据以均匀的5米深度间隔进行记录。
