Unidata - The topo/bathymetry server at http://coast-enviro.er.usgs.gov/thredds/ncss/grid/bathy/srtm30plus_v4.nc/dataset.htmlis extremely useful! What is the source of this data? Somewhere I thought I read that you had combined Smith & Sandwell bathymetry with SRTM30 topography, but I can't find that reference again.
