I can't find an attribute for elevation. This should be stored as the
first floating point attribute. What does:

s.out.ascii RedSeaBathyFinal -adi | head -10

show?


You should see:

easting northing #cat %elevation


In the actual sites file this is stored as

easting|northing|#cat %elevation



's.surf.idw field=2' would be for:

easting northing #cat %something %elevation



for topography/bathymetry, s.surf.rst might give better results too...
