Temperature profiles from XBT casts from the KNORR and other platforms as part of the International Decade of Ocean Exploration / International Ocean Studies / First Dynamic Response and Kinematics Experiment in the Drake Passage (IDOE/ISOS/FDRAKE) from 1978-09-18 to 1982-10-13 (NODC Accession 8300

Temperature profiles were collected from XBT casts from the KNORR and other platforms from 18 September 1978 to 13 October 1982. Data were collected by the National Marine Fisheries Service (NMFS) as part of the International Decade of Ocean Exploration / International Ocean Studies / First Dynamic Response and Kinematics Experiment in the Drake Passage (IDOE/ISOS/FDRAKE). 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 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data records are comprised of pairs of temperature-depth values. The XBT data files contain temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. Special instruments permit measurements to be obtained to 1830 m.1978年9月18日至1982年10月13日期间，本数据集的温度剖面数据源自诺尔号（KNORR）科考船及其他平台开展的一次性温深仪（expendable bathythermograph, XBT）观测剖面。本数据作为国际海洋勘探十年（International Decade of Ocean Exploration, IDOE）、国际海洋研究计划（International Ocean Studies, ISOS）及德雷克海峡首次动力响应与运动学实验（First Dynamic Response and Kinematics Experiment in the Drake Passage, FDRAKE）项目的组成部分，由美国国家海洋渔业服务局（National Marine Fisheries Service, NMFS）采集完成。数据经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https://www.nodc.noaa.gov/General/NODC-Archive/bt.html页面获取。 通用温深仪输出（UBT）格式存储了通过一次性温深仪采集得到的温度-深度剖面数据。每条观测记录均附带航次信息、观测位置、观测日期与时间。数据记录由多组温度-深度数值对构成。本XBT数据文件中的温度值对应非均匀分布的深度，仅通过精准刻画温度曲线所需的最少测点（即“拐点”）记录对应深度。常规一次性温深仪可获取的最大观测深度为450米或760米，特殊定制仪器则可实现1830米深度的测量。
