The SURVOSTRAL project is a high-density repeat XBT line between Tasmania and Antarctica, crossing the Southern Ocean. The SURVOSTRAL project includes XBT data available from 1992 to 2005+, and surface underway SST and SSS data from a thermosalinograph from 1993 to 2005+. XBT Temperature profiles described here are available 6-10 times per year, from 0 - 800 m depth during austral summer, from October to March. Data from 1992 to 1998 have the format described by the file oldformat.readme. Data from 1999 to 2005+ have the new format described by the file newformat.readme. A fortran program which reads the two data formats is included. Quality controlled data and data interpolated onto a fixed latitude grid are available as NetCDF files, one file per year (austral summer).
