GIS and Custom Application Support for the Gulf Coast Ecosystem Restoration Council

The scientists at the Wetland and Aquatic Science Center (WARC) have provided coastal restoration project managers and decision makers with GIS planning, database and custom application capacity since 1992. The scope and complexity of this support has increased over the years and has resulted in the development of a comprehensive geospatial and advanced application teams that provide decision...

Ecosystem Development After Wetland Restoration and Creation

Wetland restoration and creation efforts are increasingly proposed as means to compensate for wetland losses. To address the need for evaluating the development of ecosystem structure and function in restored and created wetlands, USGS compared created tidal wetlands sites to natural mangrove wetlands in Tampa Bay, Florida.

Understanding Coastal Change

Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.

Geologic Hazards and Catastrophic Events

We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.

Ocean Resources for America's Needs

Our scientists conduct research studies focused on geologic mapping, sampling and understanding of mineral and energy resources and studies of the geologic setting and processes to inform renewable energy development offshore.

Coastal and Marine Ecosystem Science

We bring together multidisciplinary expertise focused on developing tools and models to improve understanding of how healthy ecosystems function as well as how they respond to environmental changes and human impacts including ecosystem restoration. Research studies address coral reef, coastal wetland, benthic habitat and groundwater resources.

Plant Community Dynamics in a Mangrove-to-Marsh Transition Zone

Mangroves will compete with salt marsh plants in transitional areas, and recent studies have documented the expansion of mangroves into marsh habitats. To better understand the plant community dynamics in this transition zone, USGS scientists are tracking vegeation changes over time in south Florida.

Efficacy of eDNA as an Early Detection and Rapid Response Indicator for Burmese Pythons in the Northern Greater Everglades Ecosystem

Traditional approaches to locating Burmese pythons - including visual searches and trapping - have resulted in low detection. Environmental DNA - or eDNA - is increasingly being used to detect the presence of non-native species, particularly when traditional methods may not be adequate.

Wave runup during Tropical Storm Colin at Madeira Beach, Florida

This short video demonstrates wave runup and setup on a beach on a stormy day during Tropical Storm Colin. The camera, positioned in the surf zone, shows a multistory building in the background, while waves run up the shallow beach and wash sand from the eroded dune edge (scarp). The vegetation that normally protects the dune has dangling roots where the sand has been

Stony Coral Tissue Loss Disease in Biscayne National Park

The Florida Keys reefs have been experiencing a severe disease outbreak from 2014 to present called Stony Coral Tissue Loss Disease (SCTLD). Depicted here are two photographs of the same coral colony of symmetrical brain coral, Pseudodiploria strigosa, that was infected by the disease in April 2015 (left photo) and completely dead by April 2016 (right photo). One

Bent Sea Rod Bleaching

A colony of the soft coral known as the "bent sea rod" stands bleached on a reef off of Islamorada, Florida. Hard and soft corals are presently bleaching- losing their symbiotic algae – all over the coral reefs of the Florida Keys due to unusually warm ocean temperatures this summer. Months with waters warmer than 85 F have become more frequent in the last several decades

Gainesville, FL. -- The first genetic study to compare nuclear DNA of endangered Antillean manatees in Belize with Florida manatees confirmed their designation as separate subspecies. Belize’s manatees, however, were found to have extremely low genetic diversity, raising questions about their long-term genetic viability.

Florida's upper Peace River can lose large quantities of water each day to sinkholes. This loss makes the river vulnerable to running dry during periods of low rainfall and limits its ability to support ecosystems and to provide water to residents downstream.

From steamboats to jetskis, Florida's first streamgage in White Springs has seen it all. When the US Geological Survey (USGS) began first recording water levels and flows on the Suwannee River, this small North Florida town was in the midst of the state's first tourism boom. A report published by USGS this month chronicles a century of change at the state's first streamgage.
