The future of the Arctic Ocean: scientific and technological challenges in the 4-D exploration of ice-covered deep seas

Monday, September 29, 2014
Pacific Forum—3:00 p.m.

The ice-covered Arctic Ocean is one of the least explored areas of Earth. Very basic questions concern the identity, distribution, and main traits of key species, energy, carbon, nutrient budgets, and the role the ice cover plays in the Arctic ecosystems from the sea surface to the sea floor. However, no other region on Earth faces a similar rapid alteration with regard to warming and its ecological consequences. Recent investigations indicate that the current rate of sea ice retreat is changing productivity, export fluxes, and habitats quickly, but it is difficult to measure and predict the consequences of such changes without baselines. This presentation discusses recent scientific and technological advances in accelerating knowledge about the Arctic basins in all dimensions of space and time, with a focus on the link between the ice cover and the deep sea, and their wondrous forms of life.
