Gamma detectors at the St. Petersburg Coastal & Marine Science Center

Radioactive isotopes are common in nature and emit particles that can be detected, quantified, and used to characterize environmental processes. The SPCMSC alpha and gamma spectroscopy labs utilize anthropogenic and naturally-occurring radionuclides in estuarine, wetland, lacustrine sediments to determine spatial and temporal sediment deposition, facilitate

USGS scuba diver on a coral reef in Dry Tortugas National Park

The U.S. Geological Survey is conducting research to guide the recovery of the threatened Elkhorn coral, Acropora palmata, in Dry Tortugas National Park and throughout the western Atlantic. A small Elkhorn colony, raised from a fragment collected after a storm, is shown here in the foreground after it was cemented to the reef to establish a new coral population.
