Coral Reef Ecosystem Studies (CREST)

The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Environmental and Public Health Microbiology Laboratory

The microbiologists at the Environmental and Public Health Microbiology Laboratory (EPHML) develop analytical methods for the identification and quantitation of pathogenic microorganisms that can impact the health of humans and other organisms. This laboratory also develops methods for accessing aquatic, terrestrial and atmospheric drivers of toxins and disease outbreaks.

Wetlands in the Quaternary Project

Wetlands accumulate organic-rich sediment or peat stratigraphically, making them great archives of past environmental change. Wetlands also act as hydrologic buffers on the landscape and are important to global biogeochemical cycling. This project uses wetland archives from a range of environments to better understand how vegetation, hydrology, and hydroclimate has changed on decadal to multi-...

Integrating Science and Management for Optimal Prevention and Control of Invasive Nymphoides in Florida

Two invasive species of floating hearts, Nymphoides cristata and N. indica, are actively managed in Florida. A rare native species, N. humboldtiana, has been found in Florida and verified by molecular methods; this species is nearly indistinguishable from N. indica.

Elkhorn coral in Biscayne National Park

The CMHRP is testing the calcification rates of different genetic strains of threatened Elkhorn coral (Acropora palmata) to advise local and Federal agencies engaged in coral reef restoration. Elkhorn coral is the sole Florida-Caribbean species responsible for creating the reef crest, which is the geological feature responsible for protecting shorelines from wave

Low dunes near Cape Canaveral launch pads often overwash during storms

Low dunes near Cape Canaveral launch pads 39A and 39B often overwash during storm events, transporting sand landward. Critical infrastructure may be buried or flooded. In addition, significant landward transport of sand may lead to extensive shoreline erosion.

It looks like a holiday ornament, but this lovely object is a single-celled freshwater alga from the desmid family, found in the marshes of Florida’s Arthur R. Marshall Loxahatchee National Wildlife Refuge. USGS biologist Barry Rosen photographed it at 200x magnification using ultraviolent light and a fluorescence microscope. Desmids range in size from under 10 microns—

USGS Hurricane Preparedness

Before a hurricane, USGS Scientists undertake a data collection effort of a grand scale. They install a temporary mobile network of sensors along the coasts to collect additional data on the intensity of storm surge, one of the most dangerous elements of a hurricane. This effort provides critical information that allows various USGS partners and emergency responders to

November 8, 2017

Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?

April 20, 2017

In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai’i, U.S. Geological Survey researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.
