Live from the Poles:
The Polar Discovery team has documented science in action from pole to pole during the historic 2007-2009 International Polar Year, and covered five scientific expeditions. The science projects have explored a range of topics from climate change and glaciers, to Earth’s geology, biology, ocean chemistry, circulation, and technology at the icy ends of the earth. Through daily photo essays, we explain how scientists collect data and what they are discovering about the rapidly changing polar regions.
What's next for the Polar Discovery team?
Even though the International Polar Year has ended, science will continue in the Arctic and Antarctic. Stay tuned for future Polar Discovery expeditions to the icy ends of the earth.
