The distribution of carbonate on the floor of the Pacific has been remapped on the basis of 1313 points from 80 references stored in the World Ocean Sediment Data Bank of Scripps Institution of Oceanography.

While carbonate distributions are of limited use in attempting to construct dissolution profiles, major trends are identifiable.
