Characterization of Tidal Wetland Inundation in the Murderkill River Estuary

Project Contact(s)

The project supports work by the Kent County Levy Court (Kent County) to evaluate the nutrient TMDLS for the tidal portion of the Murderkill River. The project will contribute to a more robust parameterization of river-marsh interaction in the water-quality model that is being developed for the Murderkill River by Kent County. The purpose of the project is to characterize the spatial and temporal inundation of a salt marsh in the Murderkill River Estuary and to determine the feasibility of using heat as a tracer of flow to characterize inundation of other marshes in the estuary.

OFR12 Landsat View of Delaware

In Delaware some linear features recognized on the Landsat image can be related to known faults. Others are interpreted as possible faults; the causes of some lineations are not yet known. Circular features are more difficult to interpret but they are similar to the domal structures and erosional features recognized in the Gulf Coast region, for example. These and the linear features of uncertain origin can be investigated by drilling and geophysical techniques after being localized by clues provided by the satellite images.

OFR30 Evaluation of Remote Sensing and Surface Geophysical Methods for Locating Underground Storage Tanks

Delaware Code, Title 7, Chapter 74, Section 7415 states in part: "The Delaware Geological Survey shall investigate the feasibility of utilizing aerial photographs and other new advanced techniques for locating abandoned tanks." In response to this charge, the Delaware Geological Survey has completed a survey of currently available remote sensing and geophysical tools to determine which methods may be utilized to locate underground storage tanks. Limited preliminary field testing has been performed.

SP26 Historical Coastline Changes of Cape Henlopen, Delaware

Coastlines are not static features. They are shaped by the daily effects of wind, current, and wave activity. Over time, a coastline may move landward due to relative sea-level rise or low sediment supply, or seaward due to relative sea-level fall or an overabundance of sediment. Perhaps the most striking example of shoreline movement in Delaware is at Cape Henlopen which has grown northward approximately one mile in the last 160 years. Maps and aerial photographs show these changes.

The Delaware DataMIL

The Delaware DataMIL collects, maps, and serves Delaware's Spatial Data Framework, or basic map datasets, on which state agencies, local and county governments, academic GIS users, and the private sector can use for their own needs. DataMIL also provides access for Delaware topographic maps that replace the old USGS 7.5-minute topographic maps for the State.

Survey gives DataMIL web site new look, features


The Delaware Geological Survey's Delaware Data Mapping and Integration Laboratory (DataMIL) team has modified and improved the DataMIL Web site to ensure that the state geographic information systems (GIS) community and citizens can take full advantage of spatial data framework layers.

EPSCoR seed grants awarded to environmental researchers


With a focus on environmental issues important to the state, the Delaware National Science Foundation Experimental Program to Stimulate Competitive Research (NSF EPSCoR) office has awarded five seed grants to investigators whose projects aim to solve environmental problems in Delaware.
