Ph.D., University of Nottingham, England (1965)

Research Interests:

My current research involves the investigation of high-latitude glacial marine systems, paleoceanography, and ice sheet/ocean interactions, with a special focus on evidence from abrupt climate change. Geographically this research takes place on the shelves and deep sea basins off the Northeast Canadian arctic margin, between Iceland and East Greenland, and in the Ross Sea, Antarctica; thus the research involves marine research cruises on a variety of vessels.

A focus of my research (together with Anne Jennings, Adjoint Assist. Prof) has been the evidence for massive iceberg calving events in the North Atlantic from large ice streams eminating from the Laurentide (North American) Ice Sheet. This research is international in scope and we work closely with other research groups in Iceland (Marine Research Institute), Canada (Bedford Institute of Oceanography), and Norway (University of Tromso), plus joint research with colleagues at Lamont-Doherty Earth Observatory, Rice University and Hamilton College (USA).

Our temporal focus is on events during the last glacial/present interglacial cycle with a view to obtaining records with a centuries to decadal sampling resolution.

Teaching Interests:

Glacial geology; Global change (non-majors); statistics for Earth scientists.

Dr. Andrews undertakes research on paleoclimates of high latitudes using marine and lacustrine sediment cores. Major areas of research include the Canadian, Iceland, Antarctic, and Greenland margins.
