Sea-Ice Retreat From the Northeast Greenland Continental Shelf Triggers a Marine Trophic Cascade.

ABSTRACT: Climate change is causing sea-ice to retreat from Arctic ecosystems. Loss of ice impacts the ecosystem in many ways, reducing habitat area for specialist species like polar bears, releasing freshwater and nutrients, and increasing light penetration into the water column. To explore the interaction of these effects, we implemented a Northeast Greenland continental shelf parameterisation of the end-to-end ecosystem model StrathE2E. We used model output from the NEMO-MEDUSA ocean-biogeochemistry model under Representative Concentration Pathway 8.5 as driving data, which suggests the northeast Greenland continental shelf will become seasonally ice-free by 2050. We simulated half a century of climate change by running the model system to a set of steady states for each decade from the 2010s to
