Temperature profiles from MBT casts from the TANEY from Ocean Weather Station N (OWS-N) in the North Pacific Ocean from 04 June 1970 to 02 July 1970 (NODC Accession 7000816)

Bathythermograph data were collected from the TANEY within a 1-mile radius of Ocean Weather Station N (3000N 14000W) and in transit. Data were collected by the United States Coast Guard from 04 June 1970 to 02 July 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.

本数据集的海水温深仪（Bathythermograph）数据采集自TANEY号平台，覆盖范围包括N号海洋气象站（北纬30°00′，西经140°00′）周边1英里海域及航行途中区域。数据由美国海岸警卫队于1970年6月4日至1970年7月2日期间采集，该平台配备专业观测设备与人员，用于监测气象与海洋状况。数据已由国家海洋数据中心（National Oceanographic Data Center, NODC）处理为符合其标准的通用温深仪输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/bt.html获取。

UBT格式用于存储机械式温深仪（Mechanical Bathythermograph, MBT）获取的温度-深度剖面数据。MBT观测的最大深度约为285米，因此其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行信息、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存储。
