Temperature profiles from MBT casts from the QUADRA from Ocean Weather Station P (OWS-P) in the North Pacific Ocean from 22 February 1969 to 09 April 1969 (NODC Accession 6900703)

Bathythermograph data were collected from the QUADRA within a 1-mile radius of Ocean Weather Station P (5000N 14500W) and in transit. Data were collected by the Fisheries Research Board of Canada; Pacific Oceanographic Group equipped and staffed to observe weather and sea conditions. 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.
