SUMMARY:Holocene climate change in southern Greenland from chironomid assemblages and oxygen isotopes in lake sediments - Melissa Chipman
DESCRIPTION:Holocene climate change in southern Greenland from chironomid assemblages and oxygen isotopes in lake sediments\nDr. Melissa Chipman\, Syracuse University \nThursday\, October 24\, 1 pm ~ Bryand 307\nThe Arctic is the most rapidly warming place on earth\, and paleorecords offer insight into how this vast region responded to a complex suite of past changes. Ice core records from the Greenland Ice Sheet provide excellent archives of Holocene climate in the North Atlantic\, but terrestrial records from areas beyond the ice sheet\, which are key for understanding the impacts of ongoing climate change\, are sparse. I will present a new terrestrial record from lake-sediment archives spanning the past 12.5 ka from South Greenland to examine the timing and magnitude of the Younger Dryas and Holocene Thermal Maximum in this region.\nTo arrange a meeting\, contact: Dr. Jacquelyn Gill\, jacquelyn.gill@maine.edu\, 1-2305

SUMMARY:A tale of ice and fire – using lake sediments to understand fire regimes and permafrost thaw in the Arctic - Melissa Chipman
DESCRIPTION:A tale of ice and fire – using lake sediments to understand fire regimes and permafrost thaw in the Arctic\nDr. Melissa Chipman  – Syracuse University\nFriday\, October 24\, 3:10 pm ~ Murray 102\n\nAmplified warming has facilitated dramatic examples of disturbance in the Arctic. Both tundra and boreal areas have experienced unprecedented wildfire activity over the past few decades. In addition\, ice-rich areas of permafrost terrain are experiencing catastrophic degradation in the form of thermal erosion. Using paleoarchives of past fire and thermoerosional activity from lake sediments\, I assess these recent changes in the context of natural variability\, and examine the interactions and impacts of these disturbance processes in the Arctic.\nContact: Dr. Jacquelyn Gill\, jacquelyn.gill@maine.edu\, 1-2305
