Center scientists are developing computer models to study the polar oceans. These models, when compared to observations, allow us to test our understanding of the physical and biological processes in the polar oceans.  They also let us make predictions of potential future changes on seasonal, interannual, and decadal time scales. PSC is a world leader in ice‒ocean modeling. The Pan-arctic Ice Ocean Modeling and Assimilation System (PIOMAS) is a workhorse applied to many of our studies.  The Global Ice Ocean Modeling and Assimilation System (GIOMAS) is used to investigate both the Arctic Ocean and the Southern Ocean. The Bering Ecosystem Study ice‒ocean Modeling and Assimilation System (BESTMAS) is used for high-resolution studies of the Bering Sea. Our ice‒ocean modeling system has been expanded to model biological processes including primary production, nutrient cycling, and plankton functioning (the Biology/Ice/Ocean Modeling and Assimilation System, BIOMAS).   Our atmospheric modeling team is using the Weather Research and Forecast Model (WRF) to examine the impact of sea ice changes on clouds, precipitation and the distribution of heat within the Arctic.
