Integration of multiple geophysical techniques to image a submarine groundwater discharge zone

Date

A. Scott Andres of the Delaware Geological Survey, presented "Integration of multiple geophysical techniques to image a submarine groundwater discharge zone" at the 2013 National Groundwater Association Annual Summit held in San Antonio, TX Apr 28-May 1.

RI78 Subsurface Geology of the Area Between Wrangle Hill and Delaware City, Delaware

The geology and hydrology of the area between Wrangle Hill and Delaware City, Delaware, have been the focus of numerous studies since the 1950s because of the importance of the local groundwater supply and the potential environmental impact of industrial activity. In this report, 490 boreholes from six decades of drilling provide dense coverage, allowing detailed characterization of the subsurface geologic framework that controls groundwater occurrence and flow.

Delaware Geologic Research Symposium - April 16, 2013

Date

The Delaware Geological Survey is hosting a research symposium consisting of presentations related to geologic programs and research in Delaware. This meeting is targeting geoscience professionals as well as planners, engineers, and others that use geologic data. Documentation for PG or other applicable continuing education credits will be made available for those attending.

Our symposium will feature talks by the DGS staff on recent and ongoing research. Topics include modeling the impacts of wastewater irrigation on groundwater quality, new techniques for determining submarine discharge of groundwater and sea level issues, stratigraphy of the Potomac Formation, and geologic mapping in Sussex County.

Stream and Tide Gage Data for Hurricane Sandy

Hurricane Sandy was a major storm event for the tidal areas of Delaware. As a part of the mission of the Delaware Geological Survey, we have compiled preliminary data related to Delaware tide and stream levels related to the Hurricane Sandy and compared them with previous flooding records.

United States Geoscience Information Network (USGIN)

Project Contact(s)

The United States Geoscience Information Network (USGIN) initiative is the product of a partnership between the Association of American State Geologists (AASG) and the United States Geological Survey (USGS) created to facilitate discovery of, and access to, geoscience information provided by state and federal geological surveys of the United States. DGS has entered into a partnership with the Arizona Geological Survey (AZGS) to participate in USGIN by establishing a metadata clearinghouse node for Delaware.
