Reconstruction of palaeoclimate and palaeoatmospheric composition from high-altitude glaciers.
Reconstruction of environmental and climatic conditions from high-altitude glaciers. An important question in climate research is whether the magnitude and rate of the 20th century climate and environmental change exceeds the natural variability over the last millennium.
Shallow firn core from the Quelccaya Ice Cap
In the frame of this project we conducted a field campaign in October 2014 in collaboration with Douglas Hardy from the University of Massachusetts. The goal was to extend the 2003 ice core record to the present in overlap with the period of available AWS data. With our Backpack Drill we established a new depth record and collected 21 m of good quality ice core (13.93° S, 70.82° W, 5660 m a.s.l.). Transported frozen to our lab, the ice is now being analyzed for stratigraphic features, density, stable isotopes of water and concentrations of chemical impurities. Results will show soon if we succeeded to reach back to the 2003 layer. For more details and news, check out Douglas Hardy´s blog.
