We refined a suite of hydrodynamic and individual-based models to understand how climate change may impact red king crab (Paralithodes camtschaticus) recruitment in Bristol Bay, Alaska. We coupled a biophysical individual-based model (IBM) and a Regional Ocean Modeling System (ROMS) circulation model to estimate connectivity between the location of red king crab larval release and benthic settlement location in the eastern Bering Sea including Bristol Bay. We conducted ROMS hindcasts for two representative years: 1999 (cold) and 2005 (warm), and a forecast for a predicted warm year: 2037. Scientific output includes ROMS model files, IBM data files, and a red king crab habitat map. Monthly averaged hydrodynamic model output for the southeastern Bering Sea (SEBS2K). SEBS2K has ~2km2 spatial resolution and 32 vertical levles. The code is based on the Regional Ocean Modeling System (ROMS), and utilized output from a larger-scale model (Bering10K) for boundary conditions. Atmospheric forcing was based on the Common Ocean Reanalysis Experiment (CORE). Two hindcast years (1999, 2005) and one forecast year (2037) were simulated.
