Hello, I'm trying to re-project a RASTER layer but without success so far. I have the following TIFF file:

If I understood well the output of gdalinfo, the projection seems to be
EPSG:4326.
Now I want to re-project this to EPSG:3031.
I tried with the following MAP file :
MAP
NAME "antarctic"
STATUS ON
SIZE 600 400
EXTENT -8563840.576 -6450314.449 8787646.239 6466755.551
IMAGECOLOR 255 255 255
PROJECTION
"init=epsg:3031"
END
OUTPUTFORMAT
NAME png
DRIVER "GD/PNG"
MIMETYPE "image/png"
IMAGEMODE RGBA
EXTENSION "png"
END
LAYER
NAME "ocean"
TYPE RASTER
STATUS DEFAULT
DATA antarctica_sthn_ocean.tiff
PROJECTION
"init=epsg:4326"
END
END
END
... but all what I get is a gray 600x400 PNG image ...
Any idea what could be the problem ?
Thanks,
Julien
