Temperature profiles from mechanical bathythermograph (MBT) casts from the USCGC ALERT from in the North Atlantic Ocean in support of the Integrated Global Ocean Services System (IGOSS) project 18 July 1972 to 25 July 1972 (NODC Accession 7201031)

MBT data were collected from the USCGC ALERT in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the US Coast Guard from 18 July 1972 to 25 July 1972. 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.
