Temperature profiles from MBT casts from the BERING STRAIT from Ocean Weather Station V (OWS-V) in the North Pacific Ocean from 16 February 1970 to 18 March 1970 (NODC Accession 7000335)

Bathythermograph data were collected from the BERING STRAIT within a 1-mile radius of Ocean Weather Station V (3400N 16400E) and in transit. Data were collected by the United States Coast Guard from 16 February 1970 to 18 March 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.

本次采集的温深仪（Bathythermograph）数据源自白令海峡内海洋气象站V（34°00′N，164°00′E）周边1英里范围及航行途中。数据由美国海岸警卫队于1970年2月16日至1970年3月18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。数据由美国国家海洋数据中心（NODC）处理为符合其标准的通用温深仪输出（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文件格式用于存储通过机械式温深仪（Mechanical Bathythermograph, MBT）采集的温深剖面数据。机械式温深仪观测的最大深度约为285米，因此此类数据仅适用于研究海洋上层的热结构。每份观测记录均包含航次信息、观测日期、位置与时间。数据记录由成对的温度-深度数值组成，且文件内的温度数据以每5米的均匀深度间隔进行记录。
