Geological Society of America awards John Andrews the Penrose Medal

INSTAAR Fellow John Andrews has been awarded the Penrose Medal, the highest honor from the Geological Society of America (GSA). The Geological Society of America is a professional organization uniting 26,000 earth scientists from every corner of the globe, working in academia, government, business and industry, to study the mysteries of our planet and beyond and to share scientific findings.

The Penrose Medal is awarded at the discretion of the GSA Council for outstanding original contributions or achievements that mark a major advance in the science of geology.  In their citation, the GSA Council observed, "John T. Andrews is a pre-eminent geoscientist whose pioneering research has fundamentally changed our understanding of former Pleistocene ice sheets, their interaction with adjacent oceans, and their profound influence on the Earth system. He documented dynamic ice-sheet behavior that provides an analog of potential future ice-sheet behavior. He helped develop the first three-dimensional numerical ice-sheet model, and his benchmark work in developing records of relative sea level change formed the geological underpinning that led to now-standard models used to derive the rheology of the solid Earth. His analysis of the energy budget required to deglaciate the Laurentide Ice Sheet showed the importance of ice-sheet instabilities and feedbacks in causing the rapid deglaciation, with implications that continue to resonate today over our understanding about the future of Earth’s present ice sheets. His pioneering investigations of ice sheet-ocean interactions were fundamental in understanding abrupt climate changes on millennial timescales."

The medal will be awarded on Sunday, 25 September 2016, at GSA’s annual meeting in Denver.  Andrews will present a science lecture as part of the Gold Medal Lecture Series later in the week.
