U.S. ice scientists travel to Antarctica, Greenland, and mountain ranges around the world to conduct fieldwork in some of the harshest conditions on Earth. Below you can find information about current and upcoming fieldwork as well as completed fieldwork.


Current and Upcoming Fieldwork

2017-2018 Antarctic

Buried Glacier Ice Masses, Ong Valley, Transantarctic Mountains

This project will study a large body of ice that is buried beneath approximately a meter of debris in the Ong Valley of the Transantarctic Mountains of East Antarctica. Preliminary analyses of this material suggest that it could be over a million years old. Most glacial ice contains tiny air bubbles that have trapped the atmospheric gases and other atmospherically transported materials existing at the time that the ice was deposited such as plant pollen, microbes and mineral dust. Samples will be collected from this buried ice mass, down to a depth of 10 meters, and cosmogenic nuclide concentrations both in the overlying debris and in the till contained in the ice will be measured. The combined analysis of the target cosmogenic nuclides (Beryllium-10, Aluminum-26, and Neon-21) will allow the age of the ice to be uniquely determined and will enable determination of the rate that the ice is sublimating.

RAID Minna Bluff Antarctic Field Trial

This project will utilize the IDDO Deep Logging Winch to log the Rapid Access Ice Drill (RAID) Antarctic field trial (AFT) borehole drilled during the 2017-2018 summer field season near Minna Bluff, Antarctica. The RAID AFT includes a new slim version of PI Ryan Bay's optical logging device for use in the 3.5-inch diameter RAID boreholes. The optical logger will enable rapid establishment of the ice chronology in a borehole, in a few hours after drilling. This field trial will be critical in determining whether or not the RAID borehole wall roughness, and cleanliness, permits optical logging at the level of detail needed for accurate dating of the ice.
