Temperature profiles from XBT casts from the TANEY as part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) project from 12 January 1977 (NODC Accession 7700160)

Temperature profiles were collected from XBT casts from the TANEY from 12 January 1977. Data were collected by the United States Coast Guard (USCG) 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.

1977年1月12日，从"塔尼"号（TANEY）的投弃式温深仪（expendable bathythermograph, XBT）测剖面中采集得到温度剖面数据。该数据由美国海岸警卫队（United States Coast Guard, USCG）作为海洋资源监测、评估与预测（Marine Resources Monitoring, Assessment and Prediction, MARMAP）项目的一部分采集获取。国家海洋数据中心（National Oceanographic Data Center, NODC）已将数据处理为符合NODC标准的通用温深仪输出（Universal Bathythermograph Output, UBT）格式。完整格式说明可从NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/bt.html查阅获取。

UBT格式包含通过投弃式温深仪（XBT）获取的温度-深度剖面数据。每一条观测记录均附带航次信息、观测位置、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——即"拐点（inflection points）"——进行记录。标准型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。
