Warm Circumpolar Deep Water transport toward Antarctica driven by local dense water export in canyons

Morrison, Adele; Hogg, Andrew; England, Matthew Heathcote; Spence, J. Paul


Poleward transport of warm Circumpolar Deep Water (CDW) has been linked to melting of Antarctic ice shelves. However, even the steady-state spatial distribution and mechanisms of CDW transport remain poorly understood. Using a global, eddying ocean model, we explore the relationship between the cross-slope transports of CDW and descending Dense Shelf Water (DSW). We find large spatial variability in CDW heat and volume transport around Antarctica, with substantially enhanced flow where DSW...[Show more]
