DELAWARE BAY, Del.- Today the United States Geological Survey (USGS) launched a demonstration of what will be a study over the next few days of the Delaware Bay using a helicopter carrying an electromagnetic sensor.
WOODBINE, NJ – Starting around July 8 and lasting up to a month, a helicopter towing a large hoop from a cable will begin making low-level flights over Delaware Bay and nearby regions in Delaware and New Jersey as part of the U.S.
Beatrice O'Hara of Delaware Geological Survey presented a poster titled "Sediment Carbon Stock, Accumulation Rates and Potential Erosion-Induced Carbon Emissions in the Delaware Bay Tidal Salt Marshes" at "The Earth's Carbon Cycle in the 21st Century: Climate, Ecosystems, and Energy," held April
A parameterization of tidal marsh inundation was developed for the 1,200 hectares of tidal marsh along the 12-km reach of the tidal Murderkill River between Frederica and Bowers Beach in Kent County, Delaware. A parsimonious modeling approach was used that bridges the gap between the simple and often used “bathtub model” (instantaneous inundation based on tides in Delaware Bay), and the more complex modeling of shallow overland that results in the wetting and drying of tidal marshes.
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.

The Delaware Geological Survey will review recent scientific literature and assessments of sea-level change in Delaware and identify appropriate scenarios to use for planning purposes throughout the state. This project will also develop new inundation maps along Delaware's coast that correspond to the identified scenarios.
In 2015, staff of the DNREC Water Supply Section made DGS aware of a situation east of Dover where there is potential for overpumping of the Columbia aquifer by the City of Dover’s Long Point Road wellfield (LPRW) and numerous large-capacity irrigation wells in the surrounding area (Figure 1).
Sea-level rise, dissipating dunes and susceptibility to storm surges are a few of the factors that contribute to a vulnerable coast. A coast at risk means an increased potential for damage to coastal communities and ecosystems in the event of tropical systems, nor'easters or other damaging weather.
More than 40 experts representing state and federal agencies and regional universities gathered to discuss these and other important issues during the Coastal Flood Research, Modeling and Monitoring Workshop on Sept. 16.
