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: 

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.
