Assessing spatial distributions and vulnerability of stored soil carbon in St. Jones and Blackbird Marshes

Project Contact(s)

Delaware is home to extensive networks of tidal marshes, which provide an array of critical ecosystem services including carbon sequestration. These marshes accumulate carbon due to their relatively high plant productivity and relatively low rates of litter decomposition.

Creation of Improved Accuracy LiDAR-Based Digital Elevation Models for the St. Jones River and Blackbird Creek Watersheds

Project Contact(s)
In tidal wetlands, the high density of vegetation cover inhibits penetration of LiDAR pulses through the vegetation to the ground surface and low vegetation heights inhibit classification of ground point elevations. This project identities and corrects for biases found in the St. Jones and Blackbird Reserves using GPS RTK surveying and statistical analysis.

New report emphasizes planning for sea level rise

Date

A new report from the Delaware Geological Survey and Delaware Coastal Programs uses sea level research and data from nearly the last decade to help the state plan for future flooding and erosion.

Delaware updates sea level rise planning scenarios

Date

The First State is at greater risk for sea level rise because of its low-lying topography. The state has new metrics used to project the impacts of climate change in the state.
