Temperature profiles from MBT casts from the OWASCO from Ocean Weather Station D (OWS-D) in the North Atlantic Ocean from 19 March 1970 to 14 April 1970 (NODC Accession 7000470)

Bathythermograph data were collected from the OWASCO 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 19 March 1970 to 14 April 1970. 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.

本数据集包含由OWASCO在海洋气象站D（44°00′N，041°00′W）周边1英里范围内及航行途中采集的海水温度深度记录仪（Bathythermograph）数据。该数据由美国海岸警卫队于1970年3月19日至1970年4月14日期间采集。搭载观测平台已完成配置并配备专职人员，用于开展气象与海洋状况观测。数据已由NODC处理为符合其标准的通用海水温度深度记录仪输出（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文件格式用于存储由机械式海水温度深度记录仪（Mechanical Bathythermograph，MBT）采集的温度-深度剖面数据。MBT观测的最大探测深度约为285米，因此该类数据仅适用于研究海洋上层的热结构特征。每条观测记录均附带航次信息、观测日期、位置与时间，数据记录由多组温度-深度数值对构成。本文件中的温度数据以5米为固定深度间隔进行记录。
