Research Interests

Benthic  and Sub-bottom Mapping of Delaware's Coastal Areas for Natural Resource Management, 2003 – Present. Utilizing remote acoustics and ground truthing to evaluate surface and subsurface sediment distribution to aid in coastal management. The data has been used to identify: borrow sites for beach replenishment, essential fish habitat (EFH),SAV,  Holocene paleo-channels and ancestral shorelines, deposition zones, scour zones, quantify the effects of navigation dredging, and identify areas of potentially high shoreline erosion.

Utilizing Sediment Elevation Table (SET's) Networks to evaluate the wetland condition along the Delaware Coast, 2004-Present.  Ongoing effort to monitor marsh surface elevations, sedimentation rates, deep subsidence, and shallow subsidence rates in Oligohaline to Euhaline marshes.

Coastal Impoundment Accretion Study, 2008 – Present.  Evaluating historic sedimentation rates, through Pb210 and Cs137 dating and RTK-GNSS surveys in 5 coastal impoundments and five reference wetlands to identify the potential sedimentation dynamics and sustainability of managed wetlands.

Development of a Marsh Vulnerability Index for Delaware, 2009 – Present.  Ongoing effort to correlate RTK-GNSS surveys, tidal gauge data, and biomass sampling to develop a growth zonation for Spartina alterniflora. This will be used to evaluate the current and future growth conditions of Spartina alterniflora marshes on the Delaware Coast.

Outer Continetial Shelf (OCS) resource management.
