©2020 Biological and Chemical Oceanography Data Management Office.Continental shelves contribute a large fraction of the ocean’s new nitrogen (N) via N2 fixation; yet, we know little about how physical processes at the ocean’s margins shape diazotroph biogeography and activity. This dataset includes incubation data and nitrogen fixation rates using water collected at the Mid-Atlantic Bight shelfbreak front in July 2019. Rates were measured using the 15N2 bubble release method on repeat cross-frontal transects. This study was coordinated with the SPIROPA (‘Shel...
