Water temperature and salinity profile data from bottle and bathythermograph (BT) casts in the Global Ocean from multiple ships and institutions prior to 1961 (NCEI Accession 6000000)
Data has been processed by NODC to the NODC standard Bathythermograph (MBT) (C128) format.

The C128 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 …
