Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Evaluating the sediment storage and mobility in the estuary/bay/lagoon environment

The focus of this task is to examine the role that marsh and shoreline erosion contribute to the sediment budgets of the adjacent open-water estuarine system. Sediments derived from marsh shoreline erosion generally have higher organic matter content than sediments derived from the erosion of barrier islands or delivered by rivers. Understanding the sediment budget in these estuarine...

Chronological geospatial assessment and quantification of episodic impacts in wetland environments

The goal of this task is to map, characterize, and quantify cumulative episodic event-driven loss in northern Gulf of Mexico coastal wetlands over the past century using available remotely sensed data. Achievement of this goal will provide spatially explicit estimates of wetland loss/gain caused by episodic large-scale drivers versus changes from persistent drivers such as sea-level rise and...

Quantifying and explaining patterns in nutrient and sediment export from urban streams within the Chesapeake Bay watershed- Rosemary Fanelli

Urban landscapes in the Chesapeake Bay (CB) watershed are growing at a rapid pace. A key component for the Chesapeake Bay restoration effort is identifying factors that control pollutant export from urban streams. Join our diverse team of water quality experts to explore emerging approaches to quantifying and explaining patterns in pollutant export in urban streams.

Response of a tidal brackish marsh to global change drivers: an ecosystem level manipulation of warming and elevated carbon dioxide- Glenn Guntenspergen

The USGS and the Smithsonian Institution have initiated the first in situ active aboveground and belowground warming experiment in a coastal wetland that is focused on wetland temperature responses and also examines the interaction between warming, elevated CO2, and inundation frequency on wetland resilience in the face of changes in global change drivers.

Understanding the Effects of Stormwater Management Practices on Water Quality and Flow

Urban development can have detrimental impacts on streams including altering hydrology, increasing nutrient, sediment, and pollutant loadings, and degrading biological integrity. Stormwater Best Management Practices (BMPs) can be used to mitigate the effects of urban development by retaining large volumes of stormwater runoff and treating runoff to remove pollutants. This project focuses on...

Piedmont and Blue Ridge Project

The Piedmont and Blue Ridge Project is a geologic mapping project supported by the USGS National Cooperative Geologic Mapping Program. The Piedmont Blue Ridge Project aims to understand the geologic framework and tectonic evolution of terranes and basins in the Appalachian Piedmont and Blue Ridge, and their significance for water, mineral and energy resources, natural hazards, and engineering/...

Coastal Basement Geology of the Southeastern U.S. Project

This project, centered on South Carolina and Georgia, extends coastal-basement geologic mapping and related research south of a geologic map in production for pre-Cretaceous rocks beneath the Atlantic Coastal Plain from Virginia to southern New Jersey, and adds detail to a national-scale basement domain map constructed to delineate mineral-resource...

A tale of two coasts: tidal marsh persistence with changing climate and sea-level rise- Karen Thorne

The overall goal of this project is to improve our understanding of the combined effects of inundation, due to sea-level rise and storm surges, and other climate factor on tidal marsh physical and biological processes to provide guidance to natural resource managers to reduce these threats and increase resilience.

Collecting Ecological Data and Models of Living Shoreline Restoration Projects

Developing effective living shoreline restoration projects that can withstand hurricanes and storms requires a better understanding of how restoration structures reduce the impact of wave and current energy on marsh edges in estuaries and bays. Without this knowledge, existing living shoreline projects and adaptive management measures are more likely to fail, decreasing the possibility for...
