Temperature profiles from MBT casts from the CHAUTAUQUA from Ocean Weather Station V (OWS-V) in the North Pacific Ocean from 29 September 1963 to 28 October 1963 (NODC Accession 6300954)

Bathythermograph data were collected from the CHAUTAUQUA within a 1-mile radius of Ocean Weather Station V (3400N 16400W) and in transit. Data were collected by the United States Coast Guard from 29 September 1963 to 28 October 1963. 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.

本数据集的海洋测温仪（Bathythermograph）数据采集自“CHAUTAUQUA”号船只，采集范围覆盖海洋气象站V（34°00′N，164°00′W）周边1英里海域及航行途中。数据由美国海岸警卫队于1963年9月29日至1963年10月28日期间采集。该作业平台配备专业观测设备并配有人员，用于开展气象与海洋状况监测。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将所有数据处理为符合NODC标准的通用海洋测温仪输出（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文件格式适用于通过机械式海洋测温仪（Mechanical Bathythermograph, MBT）获取的温度-深度剖面数据。MBT观测的最大探测深度约为285米，因此其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行信息、观测日期、位置及时间，数据记录由多组温度-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记录。
