TUE, JUN 15, 6:00 p.m.
Permafrost in a changing climate: Arctic lake and drained lake basin systems, presented by Andy Parsekian, University of Wyoming.

The Arctic system is undergoing rapid change relative to global averages; Earth’s polar regions are clearly warming faster than any other part of the global climate system.  Warmer air temperatures and changes in precipitation patterns effect hydrologic processes and the integrity of permafrost; these changes are expected to continue or amplify in the future.  What role do Arctic lakes and drained lake basins play in carbon cycling and hydrology? How will they impact permafrost thaw? And what will the impacts be on the global climate we all share and live within? Dr. Andy Parsekian will take us on a tour of his work in the Alaskan Arctic, what his and his compatriots’ work has begun to reveal, and he will discuss potential global effects.

Distributed acoustic sensing: game changing for seismology? Presented by Zack Spica, University of Michigan.

How well do we understand the earth's interior, how well are we even able to gather data to develop that understanding? Dr. Spica will take us on a tour of an exciting new technology which looks likely to greatly enhance our ability to collect critical data about our own planet and the processes that continue to form and modify it.

Our understanding of subsurface processes suffers from a profound observation bias: ground-motion sensors are rare, sparse, clustered on continents, and not available where they are most needed. A new seismic recording technology called distributed acoustic sensing (DAS), can transform existing telecommunication fiber-optic cables into arrays of thousands of sensors, enabling meter-scale recording over tens of kilometers of linear fiber length. DAS works in high-pressure and high-temperature environments, enabling long-term recordings of seismic signals inside reservoirs, fault zones, near active volcanoes, in deep seas, or in highly urbanized areas. In this talk, we will introduce this laser-based technology and present recent cases of study around the world that prove that fiber optic is a new essential tool for seismologists.

TUE, JUL 20, 6:00 p.m.
Pleistocene glaciation and fault activity in the Teton Range and Greater Yellowstone, presented by Joe Licciardi, University of New Hampshire

The striking landscapes of Jackson Hole, Grand Teton and Yellowstone are the result of over 2.5 billion years of geologic events.  Huge glaciers, powerful earthquakes, and extensive volcanic activity have combined forces to create the dramatic scenery and wildlife habitat of this amazing place.  During the Pleistocene ice ages from about 2.5 million years to as recently as 15 thousand years ago, glaciers periodically expanded across 20,000 square kilometers of the greater Yellowstone region and reached over a kilometer in thickness.  A massive ice cap centered on the Yellowstone Plateau merged with smaller valley glaciers from surrounding high mountains, including the Teton Range.  Spectacular geologic features preserved within Grand Teton National Park document an interconnected history of glaciation and tectonic activity, as revealed by moraine ridges and other landforms that are cut by prominent scarps along the ~70-km trace of the Teton normal fault.  These interwoven glacial and tectonic histories are also linked to volcanic processes driven by the Yellowstone hotspot. 

Join University of New Hampshire geology professor Joe Licciardi as he explains the evolution of iconic glacial landscapes in Yellowstone and the Teton Range, and describes ongoing research that is exploring the connections between glaciation, faulting, and volcanism in this remarkable and geologically dynamic region.
