Trace metals in deep ocean waters: A review

Science Highlights

4 July 2012

A synthesis on the data available on the distribution of selected trace metals (i.e. Cadmium, Cobalt, Copper, Molybdenum, Nickel, Lead and Zinc) in the deep ocean from 1979 to 2009 is provided by Aparicio-González and colleagues (Aparicio-González et al., 2012). This article also identifies patterns as well as gaps in currently available data in terms of their capacity to depict their global distributions.

A great contribution for the GEOTRACES Programme !
