Impacts of climate change on red king crab larval advection in Bristol Bay: implications for recruitment variability: Habitat map data files
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 mode...
