Ice Stories:  Live from the Wilkes Land Expedition (Webcast)
Running Time:
00:20:39
On March 1st, we connected live with scientists aboard the scientific drilling vessel the JOIDES Resolution off the coast of Antarctica. Meet geologists Rob Dunbar, Carlota Escutia, and Christina Riesselman and learn about their historic expedition to Antarctica that is helping reveal the history of Earth's climate and teaching us about our climate future.

Ice Stories:  Alkenones: Natural Thermometers (Clip)
Running Time:
00:03:36
To understand how Earth’s climate system has changed over time, scientists need to find, develop and use natural recorders of temperature and precipitation. One natural thermometer comes in the form of alkenones: trans-fats produced by certain algae.
