The effects of geothermal heating on the ocean overturning circulation

Mullarney, Julia C; Griffiths, Ross; Hughes, Graham


We examine the response of an overturning circulation, driven by differential thermal forcing along the top horizontal boundary, to a small additional heat flux applied at the bottom horizontal boundary. The system forms a simple thermally-driven flow that provides insight into the ocean's meridional overturning circulation. We conclude that the additional destabilising (geothermal) heat flux tends to promote a more vigorous full-depth overturning having approximately 10% greater volume flux...[Show more]
