Arctic Marine Mammal Sea Ice Habitats
Reductions in Arctic sea ice during the past decade have elevated scientific and societal questions about the likelihoods of future scenarios. Is the recent sea ice decline an indicator of anthropogenic exacerbations to positive feedbacks that will lead the Arctic to an unprecedented future of reduced ice cover, or is the decline simply an ephemeral expression of natural low frequency climate oscillations that will eventually return the Arctic to prior conditions? This unanswered question bears significant ramifications to Arctic ecology as well as the Earth's climate system, and it is being rigorously investigated by numerous scientists throughout the world.
