Temperature profiles from MBT casts from the MCCULLOCH from Ocean Weather Station C (OWS-C) in the North Atlantic Ocean from 08 March 1965 to 02 April 1965 (NODC Accession 6500932)

Bathythermograph data were collected from the MCCULLOCH 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 08 March 1965 to 02 April 1965. 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.

本数据集收录了“MCCULLOCH”号在海洋气象站C（52°45′N，035°00′W）周边1英里范围内及航行途中获取的海水温深仪（Bathythermograph）观测数据，采集工作由美国海岸警卫队于1965年3月8日至1965年4月2日期间完成。该观测平台搭载专业观测设备并配备专职操作人员，用于开展气象与海洋环境状况监测。数据由国家海洋数据中心（National Oceanographic Data Center，NODC）处理为其标准通用海水温深仪输出（Universal Bathythermograph Output，UBT）格式，完整格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。
UBT文件格式适用于通过机械海水温深仪（Mechanical Bathythermograph，MBT）获取的温度-深度剖面数据的存储。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水体的热结构。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5米的均匀深度间隔进行记录。
