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.

Long-term trends in forest regeneration across drought and salinity gradients in the northern Gulf Coast- Beth Middleton

Relict forests are becoming more common as as climates become hotter, drier and more saline. The first sign of threat to these forests is a chronic lack of seedling and sapling recruitment. This project will help pinpoint forests at risk to help in future management.

Improving Models of Coastal Change- Chris Sherwood

Help improve models of coastal erosion and morphologic change! This project offers an opportunity to collect and process various kinds of oceanographic and morphologic data using instruments and images recorded with our beach cam and drones. Or it can be a chance to develop and test numerical models. In either case, the results will help the USGS make forecasts of coastal erosion during storms...

Coastal Habitats in Puget Sound

A Pacific Northwest icon, Puget Sound is the second-largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to growth in human population and urbanization. This growth has played a role in degrading the Sound...

Submarine Groundwater Discharge

Submarine groundwater discharge (SGD) is an ubiquitous coastal process that is driven by a composite of climatologic, hydrogeologic, and oceanographic processes. For example, terrestrial hydraulic gradients that reflect both short and long term climatic conditions almost always transport both surface and ground water toward the coast. In coastal waters, physical oceanographic processes such as...

DIGITAL SHORELINE ANALYSIS SYSTEM (DSAS)

Computer Software for Calculating Shoreline Change (or positional change of a boundary over time)

The Digital Shoreline Analysis System (DSAS) is an add-in to Esri ArcGIS desktop v.10.4 or 10.5 that enables a user to calculate shoreline rate-of-change statistics from multiple historical shoreline positions. It provides an automated method for establishing measurement...

Estuarine Processes, Hazards, and Ecosystems

Estuarine processes, hazards, and ecosystems describes several interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These projects are led from the U.S....

Sea-Level Rise Hazards and Decision Support

This project brings together scientists from the disciplines of geology, hydrology, geography, biology, and ecology to address the effects of Sea-Level Rise (SLR) on the Nation’s coasts. The project synthesizes information on coastal environments and uncertainties in knowledge of coastal processes into a Bayesian statistical analysis framework. The Bayesian approach allows researchers to...
