Temperature profiles from MBT casts from the WINONA from Ocean Weather Station N (OWS-N) in the North Pacific Ocean from 01 April 1964 to 14 April 1964 (NODC Accession 6400009)

Bathythermograph data were collected from the WINONA 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 01 April 1964 to 14 April 1964. 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.

本数据集为海水温深仪（Bathythermograph）数据，采集自“WINONA”号船只，覆盖范围包括海洋气象站N（30°00′N，140°00′W）周边1英里海域及航行途中区域。该数据由美国海岸警卫队于1964年4月1日至1964年4月14日期间采集。作业平台配备了相关观测设备并配有专业人员，用于开展天气与海况监测。美国国家海洋数据中心（National Oceanographic and Data Center, NODC）已将所有数据处理为符合其标准的通用海水温深仪输出（Universal Bathythermograph Output, UBT）格式。完整的格式说明可从NODC官网www.nodc.noaa.gov/General/NODC-Archive/bt.html 获取。

UBT格式适用于通过机械式海水温深仪（Mechanical Bathythermograph, MBT）采集的温度-深度剖面数据。该类仪器的观测最大深度约为285米，因此MBT数据仅可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、位置与时间。数据记录由温度-深度值对组成，本文件中的温度数据以5米为均匀深度间隔进行存储。
