Delaware Geologic Research Symposium - April 14, 2015

Date

The DGS is again hosting a research symposium with presentations on Delaware Geology. This meeting is targeting geoscience professionals as well as planners, engineers, and others that use geologic data.  Documentation for PG credits will be available for those attending. 

Strategic Plan for Geologic Mapping of Delaware 2016-2030

Geologic maps at the DGS are created as primary deliverables of a project and as derivatives of other projects. Primary deliverables are mainly those that are the result of outside funding sources such as the AASG-USGS cooperative StateMap. Derivative maps are those that have primary data collected for reasons other than geologic mapping can be used to create geologic maps or that geologic maps are derivative products of a project rather than the primary goal of a project.

GM23 Geologic Map of the Seaford West and Seaford East Quadrangles, Delaware

The geological history of the surficial units of the Seaford East Quadrangle and the Delaware portion of the Seaford West Quadrangle was the result of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to sea-level fluctuations during the Pleistocene. The geology reflects this complex history by the cut and fill geometry of the middle and late Pleistocene deposits incised into the Beaverdam Formation.

Geological research initiatives - Public, private, academic partners gather for Delaware Geologic Research Symposium

Date

-Public, private and academic partners came together on Tuesday, April 14, in the Rodney Room of the University of Delaware’s Perkins Student Center for the second biennial Delaware Geologic Research Symposium, hosted by the Delaware Geological Survey and the College of Earth, Ocean, and Environment.
Over 100 geological researchers, state representatives, industrial partners and University students and faculty shared and observed presentations on the latest geological research initiatives in Delaware, and what they mean for the state, its environment and its citizens.

DGS releases report on subsurface geology of Delaware City area

Date

The Delaware Geological Survey (DGS) has published a report that details new findings on the subsurface geology of the Delaware City area.

Titled Subsurface Geology of the area between Wrangle Hill and Delaware City, Delaware, Report of Investigations Number 78 presents the results of cooperative research between geological consultant John W. Jengo of the firm MWH Americas and DGS researchers Peter P. McLaughlin Jr. and Kelvin W. Ramsey.

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.

Celebrate Geologic Map Day 2012!

Date

Friday, October 19th has been designated Geologic Map Day 2012. As an extension of the National Cooperative Geologic Mapping Program of USGS, Geologic Map Day focuses the attention of students, teachers, and the general public on the study, uses, and significance of geologic maps for education, science, business, and a variety of public policy concerns.

David R. Wunsch appointed DGS Director

After a nationwide search, David R. Wunsch has been appointed the next Director of the Delaware Geological Survey (DGS) and Delaware State Geologist, effective Nov. 1. He will succeed John H. Talley, who retired on June 30 after more than 38 years of service. Wunsch holds a doctorate in hydrogeology from the University of Kentucky, a master’s degree in geology from the University of Akron, and a bachelor’s degree in geology, with a minor in chemistry, from the State University of New York, Oneonta. In 2011, Wunsch was elected a Fellow of the Geological Society of America. He is an Honorary Member and a past President of the Association of American State Geologists (AASG) and has previously served a term as Secretary of the American Geological Institute.
