A Historical Ice Core from the Heart of Europe

In 2013, a joint venture of the Climate Change Institute at the University of Maine, and the SoHP retrieved a 73-meter (240ft) ice core from the Colle Gnifetti glacier in the Swiss Alps.  Analysis of the ice core, at the Climate Change Institute, is producing invaluable new data about climate change and human-climate interactions from the last ca. 2,000 years. Concurrently, Harvard historians are combing pre-industrial written records to create a new geo-database of climate events, which complements the scientific data.

As documented here, a seven-person team from the Climate Change Institute, the Institut für Umweltphysik, University of Heidelberg (Germany) and the Physics Institute, University of Bern (Switzerland), recovered the ice core over the course of one week at the Colle Gnifetti (CG) glacier saddle of the Monte Rosa Massif (4450 m.a.s.l.).  It will be analyzed using a host of technologies not available when previous CG cores were drilled and featuring a path-breaking collaboration of humanists and scientists.

To this end the University of Maine and Harvard University have been producing ultra-high-resolution measurements of dust and other impurities using state-of-the-art laser based technology developed in the Climate Change Institute’s W. M. Keck Laser Ice Facility at the Climate Change Institute and a new historical geodatabase of the climate of pre-modern Europe from written sources, collected and analyzed at Harvard.

The resulting records are allowing the first detailed, ice core-based assessment of human-climate interactions during the last two millennia. The new technology is minimally destructive and will allow the permanent preservation of the new ice core record. The project is supported by a grant from the Arcadia Foundation.

Evaluation of this unique archive involved researchers from Alfred-Wegener-Institute, Bremerhaven (Germany) and the Department of Geosciences, University of Fribourg (Switzerland), and the University of Nottingham, (U.K.).
