FEATURES

16 Research in the Coldest Desert
Antarctica's McMurdo Dry Valleys are cold (mean annual temperature is negative 20 degrees Celsius) and dry (annual precipitation is less than 10 centimeters per year). But life exists here nonetheless, and a multidisciplinary team of scientists is working to understand how.
Berry Lyons

20 Investigating an Arctic Gateway
About 20,000 years ago, sea level in the western Arctic dropped, and the Bering Strait was a land bridge. The history of how sea level has risen and fallen in this area is just one piece in understanding the puzzle of Earth’s climate.
Julie Brigham-Grette, Lloyd Keigwin and Neal Driscoll

24 From Magnetism to Meteorites
Earth’s highest latitudes hold clues about the future of the magnetic field, the fate of ice sheets and the history of the solar system.
