The Nordic Seas in the global climate system

The great Ocean Conveyor Belt

The warm Atlantic inflow loses its excess heat and a dense overflow across the ridge is a result.

(After Hansen and Østerhus, 2000)

Deep Convection is the driver for the Conveyor Belt

Exchanges with the Arctic Ocean

•Increased influx of heat into the Nordic Seas due to Warming of the Gulf Stream ->

•Increased advectional heat flux from the Norwegian Sea into the Arctic ->

•Increased melting of the Arctic Ice ->

•Increased flux of fresher Arctic surface waters into the Greenland Sea ->

•Reduced Deep Sea convection in the Greenland Sea ->

•Reduced influx of the Nordic Sea Deep waters into N.Atlantic ->

•Reduced strength of the Conveyor Belt ->

•Reduced influx of heat into the Nordic Seas due to the Negative Feedback

Negative Feedback Rap:It's negative feedbackhere to bring it backequilibrium sustaineddon't mess with me or i'll have you down on your kneesmaking a pleeeto Jesus,save us,bring back the diverse forestso say sorry to the coccolithophores,and apologize to the ocean flooror maybe I won't save you next timeand so I finish with a rhyme.
