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. Additional topics are forthcoming.


Decision Support


Chesapeake Bay Program Geospatial Support Vision


   Why?
The role of geography in assessing conditions of and stresses to the Chesapeake Bay ecosystem is fundamental to an understanding of the optimal approach for restoring and protecting the ecosystem.

   What?
Geospatial support is critical to achieving the goals and objectives of the Chesapeake Bay Program partnership. Geospatial analysis has been and will continue to be used to establish nutrient and sediment reduction goals throughout the watershed and to assess the degree to which water quality standards are being met in the Bay. It is also being used to assess and track progress towards goals and outcomes associated with sustainable fisheries, healthy habitats and watersheds, and stewardship activities throughout the Chesapeake Bay watershed.

Visualizing the Spread of West Nile Virus and Five Other Diseases across the United States


   Why?
Map out how the West Nile Virus has spread and is spreading across the United States.

   What?
Configure maps, charts, and tables that track the spread, number of people affected, and the peak season of the virus. More information....




ChesapeakeStat


   Why?
The new Chesapeake Watershed Agreement will contain a series of goals, outcomes, and management strategies that will guide watershed restoration and conservation over the next decade. Progress towards achieving these goals and outcomes needs to be communicated to multiple Chesapeake Bay Program audiences.

   What?
ChesapeakeStat supports improved communication, accountability, and decision-making through easier access to the information Chesapeake Bay Program (CBP) partners, stakeholders, and oversight groups most often seek. Specifically, ChesapeakeStat serves as a vehicle for displaying and tracking progress toward the new Bay Watershed Agreement goals, outcomes, and, ultimately, management strategies.

Land Cover Dynamics and Environmental Processes


Construction of BMPs in a developing area in Clarksburg, Maryland. The Clarksburg Special Protection Area uses advanced construction sediment and erosion controls and stormwater BMP design in their development activities.

Best Management Practices in Developing Landscapes


   Why?
Land use change and development alters surface water flow patterns and affects landscape water quality, quantity, and timing, impacting area streams and downstream estuaries and ecosystems.

   What?
Study specific structures and actions that are designed to mitigate the negative environmental effects of land use change. More information....




Causes and Consequences of Land Use and Land Cover Changes in the Chesapeake Bay Watershed


   Why?
Over the next 30-years, continued changes to the landscape due to human activities and climate pose great challenges to our ability to restore and maintain the ecosystem.

   What?
The goals of this project are to (1) inform local and state decision-makers of the causes and consequences of land change to water quality, habitat, and hazards in the Chesapeake Bay, (2) enhance monitoring of past and present land change patters, and to (3) evaluate the impacts of past, present, and future land changes to water quality and ecosystems.
