RESEARCH/REVIEW ARTICLE Changes in the marine carbonate system of the western Arctic: patterns in a rescued data set
A recently recovered and compiled set of inorganic carbon data collected in the Canadian Arctic since the 1970s has revealed substantial change, as well as variability, in the carbonate system of the Beaufort Sea and Canada Basin. Whereas the role of this area as a net atmospheric carbon sink has be...
