GEOLOGIC RECORDS OF GLOBAL CHANGE

Stable oxygen and carbon isotope record from a box core collected from Fayetteville Green Lake, New York. Samples taken from varves document a distinct 22-year cycle that may be related to solar forcing over the past 1,000 years. Following 20 years of marine geological/geophysical studies in the Bahamas, Florida and Caribbean region, my research interests now focus on the geologic record of global change. I develop proxy records of past climatic conditions on sediment cores recovered from mid-latitude lakes. My most recent research has focused on the Finger Lakes of central New York State which house an amazingly rich, high resolution record of environmental change during the past 14,000 years. I'm currently developing high-resolution (annual to decadal scale) stable isotope records for the last deglaciation, the Holocene Hypsithermal, and subsequent Holocene Neoglacial. Near future plans include inititation of paleo-productivity studies in the Great Lakes, as well as longer term paleoclimate records. Such records provide a baseline of natural climate variability for the Northeastern United States against which future climates can be compared. Other research regions include the large glacial lakes of southern British Columbia.
