Carbon export and particulate trace metal cycling across the Western Arctic Ocean
Carbon flux estimates show contrasting patterns in export between the broad Arctic shelves and the oligotrophic central Arctic basin. Some of the longer-lived isotope data also indicate a difference in export between the Makarov and the deeper Canada Basins. These regional differences in the biological carbon pump will be explored further in the context of existing historical sediment trap data. In addition, the export fluxes of trace elements (e.g. iron, cobalt, and manganese) from these same regions will be presented. The (de-)coupling of these trace element systems with the carbon cycle in the Arctic will be examined along the shelf-basin continuum and from basin to basin within the Western Arctic Ocean to improve our understanding of the drivers of carbon and micronutrient export in this rapidly changing region.
