Materials From Arctic Shelves Are Changing the Water’s Composition
![The USCGC Healy, hosting the US GEOTRACES expedition, and the RIB Polarstern, hosting the German GEOTRACES expedition, met at the North Pole on Sept. 7, 2015. A total of three GEOTRACES expeditions (the third a Canadian cruise on the CCGS Amundsen, not pictured) were conducted in the summer of 2015; this coordinated international effort will provide a more complete understanding of the chemistry of the Arctic Ocean as a whole.

Materials from Arctic Shelves are Changing the Water’s Composition: Scientists say the input of shelf-derived materials to the central Arctic Ocean over the past decade appears to be increasing. They further note that this increase is altering the water’s composition and could threaten biological productivity and species assemblages. Their results provide one of the first […]
