CLIMATE STILL CHANGING

In The Field: Antarctica 2010: Arrival in Christchurch

After today's fitting for extreme cold weather gear, the week-long trip will take us to McMurdo Station (Antarctica's largest community, at about 5,000 researchers and staff), the Amundsen-Scott South Pole Research Station, the windswept West Antarctica Ice Sheet (WAIS) Divide and the hyperarid McMurdo Dry Valleys.

On the ice, there is a veritable treasure trove of exotic research projects. At the South Pole, astronomers search the sky for cosmic microwave background radiation from the Big Bang while physicists search the ground for evidence of neutrino collisions, visible to detectors in the pellucid ice as a faint blue glow from muons, the byproducts of the collisions. At the WAIS Divide, geologists and paleoclimatologists dig through deep ice into the climate history of the planet, pulling up ice cores that have trapped bubbles of air from ancient atmospheres.

How do we know that the chemical composition of the trapped air is unchanged from the day it was trapped?
