Abstract
InteRFACE (Interdisciplinary Research for Arctic Coastal Environments) is a new Department of Energy (DOE) project to understand and predict coupled physical, biological and human-system changes occurring at the margins of the Arctic Ocean, including Alaska’s North Slope. The project is novel because it spans the Regional and Global Model Analysis (RGMA), Earth System Model Development (ESMD), Multisector Dynamics (MSD) and Data Management (DM) programs of the DOE Office of Biological and Environmental Research, along with its sister project, Integrated Coastal Modeling (ICoM) of the North American Atlantic coast. InteRFACE Phase 1 is a close collaboration between polar oceanographers, cryospheric scientists, hydrologists, biogeochemists, economists and social scientists. Phase 1 began in October 2019 and over the next three years, we plan several key developments in E3SM, tested and benchmarked on a regionally refined oceanic mesh designed to inform navigability for Arctic shipping, and better represent coastal biogeochemistry and river outflow. We will be introducing landfast sea ice, wave-sea ice coupling, higher-order-closure-type oceanic mixing, benthic biogeochemistry and a nested permafrost hydrology model to branched versions of E3SM. These new developments will undergo strident testing and analysis within InteRFACE using fully coupled E3SM simulations, and developments demonstrated to be robust will be committed to the core E3SM project code. Our model development, analysis, and testing is being backed up by a simulation campaign focused on quantifying the spread of moderately-sized ensembles and offers the potential of significant improvements to the polar physics and biogeochemistry of E3SM.
