Marine Terraces Trace Island Geologic History
Contact: Yvonne Menard, 805-658-5725
Guest speaker geologist Daniel Muhs will share his research on marine terrace uplift rates at the Channel Islands and how this information increases our understanding of the islands biogeography at the April 13, 2011, “From Shore to Sea” lecture.
Muhs will discuss various methods used to date fossils and analyze their location in marine terraces. This knowledge allows better understanding of when the islands emerged from the sea, helping define the arrival of unique island plant and animal species.
Since 1983 Muhs has worked as a geologist with the U.S. Geological Survey in Denver, Colorado. His research interests include sea-level history, eolian geomorphology, soil science, paleo-climatology, geochronology, and stratigraphy. Muhs received B.A. and M.S. degrees from the University of Illinois and earned a Ph.D. in geology from the University of Colorado. He is currently working on a visitor’s guide to the geology of Channel Islands National Park.
The “From Shore to Sea” lecture series is sponsored by Channel Islands National Park with support from Channel Islands National Marine Sanctuary. The purpose of the series is to further the understanding of current research on the Channel Islands and surrounding waters. The lectures occur at 7:00 p.m. on the second Wednesday of March, April, May, September, October, and November. These programs, located at the Channel Islands National Park Robert J. Lagomarsino Visitor Center, 1901 Spinnaker Drive in the Ventura Harbor, are free and open to the public.
