Résumé:
The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...

1992 Résumé:
This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...
