EGSC scientists monitor and analyze changes on the land, study connections between people and the land, and provide relevant science information to inform decision making. Learn more about our research activities by selecting your topics of interest below.



USGS and State of Georgia scientists discuss relationships among land cover dynamics (recorded in satellite data) and hydrology during a field survey of the Flint River.

Flint River Vegetation Dynamics and Water Availability


   Why?
Accurate and cost effective tools are needed to estimate the impacts that changes in climate, land use, and therefore streamflow will have on aquatic habitat and species abundance.

   What?
Acquire knowledge of the impact that spatially and temporally variable land surface properties have on the hydrologic, geochemical, and energy fluxes of the watershed area that drains to the stream. More information....

Land Cover Dynamics and Environmental Processes Project


   Why?
People influence the availability and condition of water and biologic resources directly though their use and indirectly through modification of land cover.

   What?
Develop, evaluate, and apply landscape process understanding to improve the hydrologic and biologic science used in decision-making at Federal, State, and Local government levels. More information....



Marsh Dieback

Sudden Salt Marsh Dieback


   Why?
Sudden salt marsh dieback has consequently been identified as an issue of very high priority for both the U.S. Fish and Wildlife Service and the National Park Service in this region.

   What?
Develop satellite-based remote sensing techniques that can be used to accurately determine the regional severity and extent of sudden salt marsh dieback. More information....


Bear in Shenandoah Park.

Shenandoah Climate, Vegetation, and Hydrology Analysis


   Why?
Establish meteorological, land surface, and land cover tracking capabilities that form a foundation for an ecosystem monitoring network.

   What?
Examine whether climate-change related signals in Shenandoah National Park canopy phenology are detectable in satellite imagery and explore the implications of any detected signal(s) for watershed hydrology in the region. More information....



South Florida Landscape Synamics

South Florida Landscape Dynamics


   Why?
Provide restoration-critical information regarding past and current land surface characteristics of the Greater Everglades.

   What?
Use remote sensing and geospatial analysis for improved landscape scale modeling and restoration monitoring. More information....
