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...

Joint Ecosystem Modeling: Cape Sable Seaside Sparrow Helper
The Sparrow Helper tool allows for the evaluation of water management scenarios by generating, plotting, and mapping hydrologic metrics across a range of time scales to predict impacts of proposed water depth changes to sparrow subpopulations.
Joint Ecosystem Modeling: Wader Distribution & Evaluation Modeling (WADEM)
WADEM (Wader Distribution Evaluation Modeling) is a JEM model that estimates species-specific habitat suitability across the landscape for Great Egret (Ardea alba), White Ibis (Eudocimus albus), and Wood Stork (Mycteria americana).
Environmental and Public Health Microbiology Laboratory — St. Petersburg, Florida
About the 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...
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-...
Gulf Coast Petroleum Systems Project - Assessments
This site highlights the assessments of the Gulf Coast Petroleum Systems Project. Scientifically robust assessments of undiscovered, technically recoverable hydrocarbon resources are published in a variety of USGS publications. This project also conducts research on the processes that impact the formation, accumulation, occurrence and alteration of hydrocarbon energy resources (...
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.
Hurricane Matthew: Flood Resources and Tools
During and after Hurricane Matthew, the USGS made flood-flow measurements, maintained streamgages, deployed over 390 instruments, and developed geospatial products to measure and communicate the extent of coastal and inland flooding.
Joint Ecosystem Modeling: Cape Sable Seaside Sparrow Marl Prairie Indicator
Marl prairie is the most diverse freshwater vegetation community in the Greater Everglades and provides the only suitable habitat for the federally endangered Cape Sable seaside sparrow (CSSS; Ammodramus maritimus mirabilis).
Joint Ecosystem Modeling: EverSnail
EverSnail, developed in collaboration with the University of West Florida, is an age- and size-structured spatially-explicit landscape model of native apple snails (Pomacea paludosa).
Joint Ecosystem Modeling: Alligator Production Probability Model
Because the American alligator (Alligator mississippiensis) is a keystone species of the Everglades ecosystem, managers need a way to quantitatively assess the effects of alternative restoration scenarios on alligators.
