Iron Isotope Biogeochemical Cycling in the Western Arctic Ocean

Iron Isotope Biogeochemical Cycling in the Western Arctic Ocean

The Arctic Ocean is unique, connecting the Atlantic and Pacific basins and being especially vulnerable to the impacts of a changing climate. Iron stable isotopes (δ56Fe) provide a unique window into the biogeochemical cycling of Fe in the Arctic. Here we present the first seawater δ56Fe for the West...

Zusammenfassung:The Arctic Ocean is unique, connecting the Atlantic and Pacific basins and being especially vulnerable to the impacts of a changing climate. Iron stable isotopes (δ56Fe) provide a unique window into the biogeochemical cycling of Fe in the Arctic. Here we present the first seawater δ56Fe for the Western Arctic Ocean, from the 2015 U.S. GEOTRACES GN01 transect. Samples analyzed for δ56Fe include seawater dissolved (
