Professor Ridge is an expert on glacial cycles, with emphasis on how the last deglaciation in the northeastern U.S. influenced climate in North America. This investigation involves a reconstruction of the changes in the sediments left by ice sheets (varves) over centuries. The varve records provide crucial information about climate changes over long periods of time. The varve records also indicate when ancient habitation was possible or not.
