John Andrews chosen for GSA Distinguished Career Award

John Andrews has been chosen to receive the Distinguished Career Award with the Quaternary Geology and Geomorphology Division of the Geological Society of America. The award will be presented at the QGG awards ceremony at the October 2007 GSA meeting in Denver. Winners in recent years have included P.W. Birkeland, W.B. Bull, N. Rutter, D.C. Ford, W.B. White, and S.C. Porter.

From the nomination letter (Peter Clark, Gifford Miller, et al): John T. Andrews owns at least three legacies for Quaternary geology and geomorphology. First, John was responsible for a paradigm shift away from a Last Glacial Maximum (LGM) ice advance extending onto shelves to a model of restricted LGM ice in the eastern Canadian Arctic. Supporting evidence for this model included strong vertical gradients in bedrock weathering and thick sedimentary fills spanning the Quaternary. John embraced many new technologies, including AMS 14C, U-Series, and Amino Acid Racemization, to support the new paradigm, which only recently was shown to favor differential glacial erosion as opposed to long periods without glaciation. Cosmogenic Exposure (CE) dating now indicates that non-erosive cold-based ice covered many coastal sediment fills at the LGM without leaving any trace beyond a few scattered erratics. Second, John made a mid-career transition to the study of ocean sediment cores, initially recognizing Heinrich events in Labrador Sea sediments that suggested partial collapses of the Laurentide Ice Sheet, then participating in numerous ocean sediment drilling projects in areas surrounding Iceland and South Greenland, work that continues today. Third, perhaps John's most enduring legacy has been to populate our profession with 29 Ph.D.s and an even greater number of students with M.S. degrees.
