Geological Map of Arctic

Available from Natural Resources Canada is this detailed geological map of the Arctic. The map was completed in November 2008 as part of a two-year, seven-nation collaboration. Resources as minerals, gas and oil could be very often found in similar geological formations.
“The Europeans, the Russians, they’ve been at it much longer than we have in terms of mineral and energy exploration in their Arctic,” said Marc St-Onge, a research scientist with the Geological Survey of Canada in an interview. “Knowing where they have their mineral deposits and gas and oil fields, we can use the geology of this consistent map … to see where else we should be looking Canada.”
The Arctic is continuously facing new claims by the surrounding countries. Russia placed a flag on the sea bed at the North Pole and recently Norway expanded its ambitions in the Barents Sea and gave a green light for a $4.2 billion project.
“Goliat is the first oil field in the Barents Sea that will be developed. Goliat is the biggest industrial project to ever be undertaken in northern Norway,” said Norway’s Oil And Energy Minister Terje Riis-Johansen in a statement.
Is there a need to model these kind of economic feedback effects on a melting Arctic? Or is the Arctic anyway ice-free , when the carbon found there is all burned?
