Sampling sediment following wildfires

In August of 2020, the enormous CZU wildfire complex consumed over 85,000 acres in San Mateo and Santa Cruz Counties, leaving scarred landscapes in the hilly region. Runoff from large rainstorms in the winter months carry contaminants from the soils within these burned-out forests. Forest fires and the fire retardants used to help control and extinguish them introduce

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.
