Temperature profiles from MBT casts from the MINNETONKA from Ocean Weather Station N (OWS-N) in the North Pacific Ocean from 07 July 1966 to 01 August 1966 (NODC Accession 6600044)

Bathythermograph data were collected from the MINNETONKA 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 07 July 1966 to 01 August 1966. 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.

本数据集为海水温度深度记录仪（Bathythermograph）观测数据，采集自明尼通卡号（MINNETONKA），覆盖范围包含N号海洋气象站（Ocean Weather Station N，坐标北纬30°00′、西经140°00′）周边1英里半径海域及航行途中。数据由美国海岸警卫队于1966年7月7日至1966年8月1日期间收集。该作业平台配备专业观测设备与操作人员，用于开展气象与海洋环境观测。数据已由美国国家海洋数据中心（National Oceanographic Data Center，NODC）处理为符合其标准的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官网链接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。每条观测记录均包含航次信息、观测日期、观测位置与观测时间。数据记录由若干组温度-深度数值对组成，本文件中的温度数据以5米为固定深度间隔进行采集记录。
