Data

Glaciochemical measurements completed
Major ion, trace and rare earth element concentrations were determined for selected samples in cores and trenches from 2009 and 2010. Analysis is ongoing.

Time-scale
Time-scale for the AH MIF is established using δD (ice) in combination with ⁴⁰Ar_atm and δ¹⁸O_atm of trapped gases from Princeton University. Data set is available from NSIDC.

Stable water isotopes
15 cm resolution δD along a 225 m core and 10 m resolution δD along the flowline are available from NSIDC.

GPS data
Download GPS Ice Flow Measurements from 2009 and 2010, Allan Hills, Antarctica from NSIDC.

Download GPS data from 2010 season from UNAVCO's online database.

PROJECT SUMMARY

Our research is enhanced by studies previously conducted in Allan Hills blue ice area (BIA).
Fundamental uncertainties remain in our understanding of natural and human-imposed climate changes, and in the factors controlling climate dynamics over the past several million years.

The Allan Hills are believed to contain ice as old as 2.8 million years (Harvey, 1998; Scherer, 1997) at the ice surface. 2MBIA is a collaborative research project, funded by the National Science Foundation Office of Polar Programs, focused on exploring the climate archive in the Allan Hills BIA.

EXPEDITIONS

Study Area. The Allan Hills are on the western flank of a portion of the Transantarctic Mountains known as the Convoy Range. The range is a barrier to ice flow that splits the East Antarctic Ice Sheet into the Mackay and Mawson outlet glaciers.
