CCPO's Dinniman to Lead Seminar Exploring Climate Change Affecting Antarctica

Mike Dinniman, a researcher with Old Dominion University's Center for Coastal Physical Oceanography (CCPO), will discuss winds and water currents affecting ice sheets along the western Antarctic Peninsula at a CCPO seminar Monday, Oct. 4.

The seminar, which is free and open to the public, will be in Room 3200 of Research Innovation Building 1 in University Village. A reception with refreshments begins at 3 p.m. and the seminar presentation follows at 3:30.

The topic of Dinniman's talk is "Wind Effects on Circumpolar Deep Water Intrusions onto the West Antarctic Peninsula Continental Shelf." He will describe results from a modeling study designed to shed light on changes in the distribution and frequency of intrusion of the relatively warm circumpolar deep water (CDW).

Changes in either the temperature or quantity of CDW moving onto the Antarctic continental shelf have been proposed as a possible mechanism in some areas for increases in the basal melt rate of the floating ice shelves at the edges of the West Antarctic Ice Sheet.

Dinniman's research interests are in using computer models to study different bodies of water, such as the Pacific Ocean, the regional seas around Antarctica and the Chesapeake Bay.
