RIVERSIDE, Calif. Peter M. Sadler, a professor of geology at the University of California, Riverside, has received two prestigious honors: He has been awarded the 2012 ICS Medal of the International Commission on Stratigraphy (ICS) for his high-quality research in stratigraphy, the branch of geology that studies rock layers as an archive of Earth history; and he has been selected to deliver the 2012 William Smith Lecture of the Geological Society of London, the oldest geological society in the world.
Sometimes called the Stratigraphy Prize, the ICS Medal recognizes a singular major achievement in advancing stratigraphic knowledge.
Sadler, who joined UC Riverside's Department of Earth Sciences in 1976, is being recognized by the ICS for CONOP (short for CONstrained OPtimization), software he developed to find and analyze the sequence of first- and last-appearances of thousands of fossil species that best fit the records of strata from hundreds of localities.
The award letter to Sadler notes that CONOP's "use in compiling and sequencing voluminous stratigraphic data is especially valuable, providing unique compilations of and insights into the stratigraphic record, and it is being widely applied."
ICS is the largest scientific body of the International Union of Geological Sciences. The ICS Medal is awarded once every four years to coincide with their International Geological Congress (IGC). Sadler will receive the medal in early August, when the IGC meets in Brisbane, Australia.
