Research Interests
- His pioneering research in developing the Fe grain chemical fingerprinting technique has lead to the discovery of massive
surges of glacial icebergs into the Arctic Ocean several times in the past corresponding to and perhaps matching in ice volume
the well-documented Heinrich Events in the North Atlantic, the influence of the Arctic Oscillation on ice drift over the last
10,000 years and that it has both century-scale and millennial-scale cyclicity, and new insights into sediment entrainment
and transport by sea ice in the Arctic.
