SAS Researchers Study Erosion at El Yunque Rock
To understand how erosion has affected the rock and surrounding mountains, a research team from the University of Pennsylvania and the National Science Foundation-supported Luquillo Critical Zone Observatory, led by Jane Willenbring, Assistant Professor of Earth and Environmental Science; Frederick Scatena, Professor of Earth and Environmental Science; and Gilles Brocard, a postdoctoral resesarcher, sought to quantify the current rate of erosion and to employ a new approach to calculate how the rate has changed through time. This new technique involves counting the isotopes that are produced and accumulate in rocks when they are hit by cosmic rays.
