As a replacement for ETOPO2

http://www.shadedrelief.com/cleantopo2/index.html

CleanTOPO2 is a touched up and generalized version of SRTM30 Plus, a 
public domain dataset that combines sea floor and land elevation data of the 
entire world. The intent of these changes is to create an elevation dataset 
more applicable to the graphical needs of cartographers, such as for making 
shaded relief and 3D panoramas. SRTM30 Plus and an earlier related dataset, 
ETOPO2, feature bathymetry data released by Smith and Sandwell in 1997. 
As remarkable as this dataset is, it nevertheless contains numerous artifacts 
that mar map presentations. In CleanTOPO2, manual editing to the elevation 
data itself has removed many of the bathymetry artifacts (Figure 1). Until the 
day arrives that improved bathymetric data are released by the scientific 
community, CleanTOPO2 offers a stopgap solution for those creating maps 
and related graphics.

CleanTOPO2 has been in turn replaced by Blue Earth Bathymetry by Tom Patterson, available from http://www.shadedrelief.com/blue-earth/.
