Lakes During the Deglaciation

"Lakes During the Deglaciation" with Jacky Austermann.

"What they tell us and why they matter"

From the researchers:

"Lakes interact with the solid Earth and climate system in many ways. We modeled proglacial lakes (lakes that form at the ice sheet margin) around the former Laurentide ice sheet with a glacial isostatic adjustment model and argue that they may speed glacial collapse. Since glacial isostatic adjustment caused proglacial lakes to be bigger during the deglaciation than the glaciation, this process may contribute to the sawtooth shape of ice age climate. I’ll also show that shorelines of proglacial lakes and ice adjacent pluvial lakes have been shaped by the load of the lake and ice sheet, providing information about the viscoelastic structure of the solid Earth."
