John T. Andrews

Professor of Geological Sciences
Fellow, Institute of Arctic and Alpine Research.

Ph.D., 1965, D.Sc., 1978, University of Nottingham, England

Research Interests:
Main research interest is in the Quaternary history of Arctic areas with special interest in glacial and glacial marine systems. Current work includes a study of piston cores from the fjords of Baffin Island and East Greenland, the Labrador Sea, and from Hudson Strait, and from the East Greenland and Iceland shelves. In addition, work is being conducted on sediments from the Ross Sea, Antarctica. The overall objective is to discuss the sediment fluxes in the terrestrial to deep-sea pathway and how this changes during intervals of climate change. In cooperation with scientists from Iceland, a study of lake and near-shore marine sediments and climate proxy indicators is underway. Techniques used in the glacial marine studies include clay mineralogy, floral and faunal variations, rock magnetic variations, and studies of the stable isotopic composition of foraminifera. Research is being carried on in cooperation with researchers at the Atlantic Geoscience Center (Canada), University of Tromso, Icelandic Marine Institute and the University of Iceland, and GeoMar (Germany).

He also helps direct the undergraduate Honors program.
