Research in the Stable Isotope Laboratory at the University of Miami's Rosenstiel School of Marine and Atmospheric Science centers on the application of stable isotopic tracers to geologic, biologic, and environmental problems. Projects range from paleo-oceanographic studies of climate change in the Holocene to modern-day analyses of pollution impacts on corals and coastal resources of Florida. Faculty, staff, and students are conducting research on a global scale including extensive research in the Florida Everglades and Florida Bay, The Bahamas, The Dominican Republic, Africa, Saudi Arabia, and Europe. In addition to measuring the stables isotopes of H,C,N, and O we have ICP-OES, XRD, IC, and GC-MS equipment.
