Temperature profiles from XBT casts from the EDGAR M. QUEENY as part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) project from 13 April 1981 to 14 April 1981 (NODC Accession 8100562)

Temperature profiles were collected from XBT casts from the EDGAR M. QUEENY from 13 April 1981 to 14 April 1981. Data were collected by the National Marine Fisheries Service (NMFS) 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.

1981年4月13日至14日，研究人员从"EDGAR M. QUEENY"号科考船的抛弃式温深仪（expendable bathythermograph, XBT）投放剖面中采集了温度剖面数据。该数据由国家海洋渔业局（National Marine Fisheries Service, NMFS）作为海洋资源监测、评估与预测（Marine Resources Monitoring, Assessment and Prediction, MARMAP）项目的一部分采集完成。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。

UBT格式存储了使用XBT仪器获取的温度-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数据文件包含非等深分布的温度值，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XBT可获取的剖面最大深度为450米或760米，特殊定制仪器则可实现1830米深度的测量。
