Matt Alkire leads the PSC team of authors that earned the Editor’s Highlight for AGU’s recent JGR: Oceans issue. Read on to learn why Matt’s article, A meteoric water budget for the Arctic Ocean, was singled out…

Matt Alkire, John Guthrie and Jamie Morison were part of an international team of researchers that studied the effects of the Atlantic Ocean on sea ice cover in the eastern Eurasian Basin of the Arctic Ocean. Read the findings published in Science Magazine.

The observatory is staffed by an international research team that establishes a camp at the North Pole each spring to take the pulse of the Arctic Ocean and learn how the world’s northernmost sea helps regulate global climate.

Investigator Matthew Alkire was recently awarded a 2012-13 Fulbright U.S Scholar Grant for his proposal titled, “Using sea ice cores to investigate the influence of glacial meltwater in surface waters of Kongsfjorden.”

There are two primary goals of this project: (1) determine whether relatively small Canadian Arctic rivers significantly contribute to the total volume of freshwater that drains through Davis Strait and (2) determine if they are chemically distinct from larger North American rivers such as the Mackenzie and Yukon Rivers.  To achieve these goals we have collected water samples from eight different rivers across Nunavut and the Northwest Territories to determine their geochemical signatures (e.g., d18O, total alkalinity, barium, Sr isotopes, major ions, and dissolved organic carbon).  The first year (2014) of field work is completed and chemical analyses of river samples are ongoing.  The second (2015) and third (2016) years of the project will involve a continuation of the river sampling efforts as well as extending sampling into the adjoining estuaries to assess changes across the salinity gradient.
