ASIS:Data bed

This is the dataset provided by Jon Bamber. It is a combination of BEDMAP and AGASEA data, Jon used the BEDMAP bed elevations and updated these with the new AGASEA thickness data and his DEM for the ASE sector only. There is quite a big jump in join areas, and the data was masked using Jon's mask.

I think the join is going to be a bit of a problem, so I'm going to suggest that I should take (grounded) ice thickness from BEDMAP and AGASEA and join them together a bit more smoothly, then create a new bed dataset from this and Jon's surface DEM? Then I'd join this onto the bathymetry data from the original BEDMAP.
