N2O dynamics in the western Arctic Ocean during the summer of 2017
Abstract The western Arctic Ocean (WAO) has experienced increased heat transport into the region, sea-ice reduction, and changes to the WAO nitrous oxide (N 2 O) cycles from greenhouse gases. We investigated WAO N 2 O dynamics through an intensive and precise N 2 O survey during the open-water seaso...
