For Antarctic data I normally use a Polar Sterographic projection, at 
least with GMT. It doesn't generate maps with rectangular borders 
though. Depending on what you are trying to do with the data, that or a 
suitable Equidistant or Equal Area projection will work OK.

I'm assuming GRASS will work OK, as I use Proj4 & PostGIS to manage the 
data for use with QGIS & GMT.

There is some info on this sort of thing at the NOAA NATICE website and 
at the British Antarctice Survey (BAS) SCAR/ADD sites. The Antarctic 
advice is just as useful at the other pole :-)

Googling for these acronyms will find the sites.
