Delaware, Maryland and Virginia have each partnered with the Bureau of Ocean Energy Management to find new sand sources using existing mapping data. As part of the federal Disaster Relief Appropriations Act of 2013, which allocated $13.6 million to the bureau, all three states will each receive $200,000 for the two-year project.
The Delaware Data Mapping and Integration Laboratory (DataMIL) officially retires on June 30, 2013.
OneGeology (http://www.onegeology.org/) is an international effort to make available digital geologic map data from around the world. DGS participates in OneGeology by submitting two web map services, one for 1:100K scale surficial geologic units and one for 1:100K scale surficial geologic contacts. These services are open and interoperable (supporting both WMS and WFS protocols) with data attributes in GeoSciML-Portrayal format.
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. Co-authors were Holly Michael, John Madsen, Chris Russoniello, and Cristina Fernandez of the UD Dept of Geological Sciences, John Bratton of NOAA, and VeeAnn Cross of US Geological Survey.
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 2013
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.
