Temperature profiles from MBT casts from the DUANE from Ocean Weather Station D (OWS-D) in the North Atlantic Ocean from 02 September 1965 to 24 September 1965 (NODC Accession 6500780)

Bathythermograph data were collected from the DUANE within a 1-mile radius of Ocean Weather Station D (4400N 04100W) and in transit. Data were collected by the United States Coast Guard from 02 September 1965 to 24 September 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.

本数据集包含采集自DUANE号的海水温度深度记录仪（Bathythermograph）数据，采集范围覆盖海洋气象站D（44°00′N，41°00′W）周边1英里海域及航行途经区域。数据由美国海岸警卫队于1965年9月2日至1965年9月24日期间采集。该观测平台配备专业观测设备并配备作业人员，用于开展气象与海洋状况监测。数据已由国家海洋数据中心（National Oceanographic Data Center，NODC）处理为NODC标准通用海水温度深度记录仪输出格式（Universal Bathythermograph Output，UBT）。完整格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/bt.html查询获取。
UBT文件格式专用于存储通过机械式海水温度深度记录仪（Mechanical Bathythermograph，MBT）获取的温度-深度剖面数据。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水体的热结构特征。每条观测记录均包含航次信息、观测日期、位置与时间。数据记录由多组温度-深度值对组成，本文件中的温度数据以5米为固定深度间隔进行存储。
