What Are They Doing?

This research project on the Greenland ice cap examined the air trapped in firn (old snow that has recrystallized into a more dense substance through the weight of the overlying snowpack) for clues to past climates. The unique characteristics of firn allow the sampling of large quantities of pre-industrial air to explore anthropogenic effects on the atmosphere. While in the field, the team conducted a variety of snow measurements; post-field analysis of the data enabled a better understanding of past climates and the impact of human activity on the Earth's atmosphere.

Where Are They?

The team traveled to Summit Station, located at the peak of the Greenland ice cap atop 3200 m of ice. Summit is a scientific research station sponsored by the National Science Foundation that supports a diversity of scientific research, including year-round measurements of air-snow interactions that provide crucial knowledge for interpreting data from deep ice cores drilled both at Summit and elsewhere.
