The great Ocean Conveyor
Belt
Deep Convection is the driver
for the 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)
Exchanges with the
Arctic Ocean
Negative Feedback in the
Climate System
•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 feedback
here to bring it back
equilibrium sustained
don't mess with me or i'll have you down on
your knees
making a pleee
to Jesus,
save us,
bring back the diverse forest
so say sorry to the coccolithophores,
and apologize to the ocean floor
or maybe I won't save you next time
and so I finish with a rhyme.
