Shelf–to–basin shuttle of highly fractionated chromium isotopes in the Arctic Ocean

This dataset contains total dissolved chromium concentration and isotopic ratios in seawater associated with our paper "Shelf–to–basin shuttle of highly fractionated chromium isotopes in the Arctic Ocean" (submitted and accepted in Geochimica Cosmochimica Acta).

The seawater samples were collected during the 2015 ArcticNet/Geotraces cruise aboard the CCGS Amundsen along the sections GN02 and GN03. 

All processing and measurements were done at the Saskatchewan Isotope Laboratory at the University of Saskatchewan (Canada).

This data will also be available in the next GEOTRACES Intermediate Data Product (November 2025).
