CCPO Seminar Offers New Look at Bioturbation

William Dewar of Florida State University will speak on "Marine Bioturbation" in the first spring-semester seminar of Old Dominion University's Center for Coastal Physical Oceanography, Monday, Jan. 25, at 3:30 p.m.

As the Pierre Welander Professor of Oceanography at FSU, Dewar has done research on understanding the dynamics of the ocean from scales of about 100 kilometers to 10,000 kilometers. Phenomena at these scales exhibit several different behaviors, from completely free evolution to directly forced evolution, and have a number of interesting characteristics.

He will contend in this lecture that the marine biosphere, by a mechanism akin to the bioturbation normally recognized in marine sediments, appears to contribute to ocean mixing energy at a rate comparable to the winds and tides. Ocean mixing is a focus in oceanography because of its relevance to ocean circulation and climate studies.

The seminar, which is free and open to the public, will be held in Room 3200 of the Center for Coastal Physical Oceanography in Innovation Research Park Building 1. A reception with refreshments begins at 3.
