Project: Changes of runoff in Arctic and the the effects of the transport in Arctic Ocean on North Atlantic circulation

---

As global warming melts the Arctic’s permafrost, more Arctic runoff is released into the Arctic Ocean, affecting the Atlantic Meridional Overturning Circulation(AMOC) and even the world’s oceans. Previous studies have shown that as runoff increases, the path of runoff in the Arctic Ocean and the strength and cycle of the AMOC also change. However, the specific changes of runoff pathways in Arctic Ocean and AMOC are not clear. There was still a knowledge gap on how the thawing permafrost affect the generation of runoff in Arctic. This study is to use VIC (Variable Infiltration Capacity) to simulate the Arctic basin and use ECCO2 global ocean circulation model to Study the the effects of runoff on the ocean, therefore to provide new insights into the hydrological processes in the Arctic.
