Temperature profiles from MBT casts from the CHAUTAUQUA and other platforms from Ocean Weather Station N (OWS-N) in the North Pacific Ocean from 19 November 1963 to 18 July 1968 (NODC Accession 6900791)

Bathythermograph data were collected from the CHAUTAUQUA and other platforms within a 1-mile radius of Ocean Weather Station N (3000N 14000W) and in transit. Data were collected by the United States Coast Guard and Ships of US NAVY; Ships of Opportunity from 19 November 1963 to 18 July 1968. 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，采集自查塔努加号（CHAUTAUQUA）及其他位于海洋气象站N（30°00′N，140°00′W）1英里半径范围内的平台，同时涵盖航行途中的观测数据。数据采集时段为1963年11月19日至1968年7月18日，采集方包括美国海岸警卫队（United States Coast Guard）、美国海军（US NAVY）舰艇及自愿观测过路船（Ships of Opportunity）。相关平台配备专业观测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（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）。完整的格式说明可通过NODC官网获取，网址为www.nodc.noaa.gov/General/NODC-Archive/bt.html。 UBT文件格式用于存储通过机械海水温度深度记录仪（Mechanical Bathythermograph，MBT）获取的温深剖面数据。MBT观测的最大探测深度约为285米，因此该类数据仅适用于研究海洋上层的热结构。每份观测记录均包含航次信息、观测日期、位置与时间。数据记录由温深数值对组成，该文件中的温度数据以5米的均匀深度间隔进行记录。
