What Controls the Formation of Antarctic Bottom Water at Cape Darnley, East Antarctica? Dense shelf water (DSW) export from Cape Darnley, East Antarctica is enhanced by nearby polynyas, but suppressed by ice shelf melt Simulations show shutting down Mackenzie polynya cuts DSW export...

Thank you! So unlike the reduced #AMOC cooling of Europe, you are saying that the main problem with the Antarctic equivalent #AABW is slowing down global oxygen and nutrition transport across the whole ocean systems?

Southern Ocean influence on Atlantic Meridional Overturning Circulation across climate states - Nature Communications The properties of the Antarctic Bottom Water largely determine the Atlantic Meridional Overturning Circulation’s depth and strength across climate states by affecting the routes via which North Atlant...

Song et al. show that the properties of the #AABW largely determine the #AMOC depth and strength across climate states by affecting the routes via which North Atlantic Deep Water returns to the ocean surface. #LGM, #ClimateChange
