Earth Sceinces Seminar Series - March 18 at Noon in UL1126

Monday, 18 March 2013 - 12:00pm - 1:00pm
University Library UL 1126

Please joins us Monday March 18th at 12 pm in UL 1126 as Pratigya Polissar of the Lamont-Doherty Earth Observatory discusses "Cenozoic Elevation History of the Tibetan Plateau".

The Tibetan Plateau is the largest region of contiguous high elevation on earth.  Uplift of the plateau during the past 50 million years is hypothesized to have affected global and regional climates.  However, the timing and mechanisms for uplift remain controversial because quantitative estimates of paleoelevation are difficult to produce.  Using a novel approach based upon organic molecules in ancient sediments, new measurements are shedding light on when the plateau was uplifted and whether tectonic uplift of the plateau has affected climate of the past 50 million years.
