Temperature profiles from XBT casts from the AMERICAN ARGO as part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) project from 28 May 1979 to 29 May 1979 (NODC Accession 7900251)

Temperature profiles were collected from XBT casts from the AMERICAN ARGO from 28 May 1979 to 29 May 1979. Data were collected by Moore-McCormack Lines Inc. as part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) project. 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 permitted measurements to be obtained to 1830 m.1979年5月28日至1979年5月29日期间，从美国ARGO（AMERICAN ARGO）的投弃式温深仪（expendable bathythermograph, XBT）投放剖面中获取了温度剖面数据。该数据由穆尔-麦科马克航运公司（Moore-McCormack Lines Inc.）作为海洋资源监测、评估与预报（Marine Resources Monitoring, Assessment and Prediction, MARMAP）项目的一部分收集完成。数据由美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准通用温深仪输出（Universal Bathythermograph Output, UBT）格式。完整的格式说明可从NODC获取，网址为：www.nodc.noaa.gov/General/NODC-Archive/bt.html。 通用温深仪输出（UBT）格式包含使用投弃式温深仪（XBT）获取的温度-深度剖面数据。每次观测均记录航次信息、站位坐标、观测日期与时间。数据记录由温度-深度值对构成。XBT数据文件中的温度值对应非均匀分布的深度，这些深度以精准刻画温度曲线所需的最少测点（拐点，inflection points）进行记录。标准型XBT可获取最大深度为450米或760米的温度剖面，特殊定制仪器则可实现最大1830米深度的测量。
