I've just come across the Global Multi Resolution Topography dataset.
It combines multibeam sonar with satellite bathymetry to produce a DEM
of the oceans, and uses SRTM for the land. Data can be downloaded at ~1
arcsecond resolution (~90 m).
I've put links and more information on the wiki:
http://grass.osgeo.org/wiki/Global_datasets#Global_Multi-Resolution_Topography_.28GMRT.29
There is a WMS server for the data but I haven't managed to use it
successfully. Instead, I downloaded tiles using wget, which I found
very convenient. I generally have mixed results with r.in.wms.
Cheers
John
