Temperature profiles from MBT casts from the VANCOUVER from Ocean Weather Station P (OWS-P) in the North Pacific Ocean from 12 August 1968 to 22 September 1968 (NODC Accession 6900709)

Bathythermograph data were collected from the VANCOUVER within a 1-mile radius of Ocean Weather Station P (5000N 14500W) and in transit. Data were collected by the Fisheries Research Board of Canada; Pacific Oceanographic Group from 12 August 1968 to 22 September 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.本数据集为采集自"温哥华"号的海水温深仪（Bathythermograph）数据，采集范围覆盖海洋气象站P（50°00′N，145°00′W）周边1英里海域及航行途中。该数据由加拿大渔业研究委员会太平洋海洋学组于1968年8月12日至1968年9月22日期间采集。该观测平台配备专业观测设备并配有作业人员，可开展气象与海洋环境状况监测。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温深仪输出（Universal Bathythermograph Output, UBT）格式。完整的格式说明可通过NODC官网的以下链接获取：www.nodc.noaa.gov/General/NODC-Archive/bt.html。 UBT文件格式用于存储通过机械式温深仪（Mechanical Bathythermograph, MBT）获取的温度-深度剖面数据。机械式温深仪的最大观测深度约为285米，因此此类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行信息、观测日期、位置及时间戳，数据记录由温度-深度数值对构成。该文件中的温度数据以5米的均匀深度间隔进行存储记录。
