Digital Mapping Techniques 2014 Workshop

Hosted by the Delaware Geological Survey, Association of American State Geologists, and the U.S. Geological Survey.
University of Delaware
Newark, Delaware
June 1-4, 2014

The 18th Annual Workshop on Digital Mapping Techniques (DMT'14) will be held June 1-4, at John M. Clayton Hall Conference Center at the University of Delaware, Newark, Delaware. Each year, these meetings have served a critical role for the geosciences, fostering informal discussion and exchange of technical information among scientists, cartographers, and GIS specialists, primarily from State and Federal agencies, who are using digital techniques to create, publish, manage, and analyze geologic maps and data.

DGS and DEOS add new on-line groundwater level station

Date

DGS and Delaware Environmental Observing System (DEOS) staff are pleased to announce that real-time groundwater level data from well Cb51-184 located next to the DEOS weather station on the University’s College of Agriculture Newark campus are now available.

OFR54 Bedrock Geologic Map of the Delaware Piedmont

The Piedmont rock units in Delaware, and bedrock geologic map of Schenck et al. (2000) are revised in this report based on new rock geochemistry, geochronometric data, petrography, and recent detailed mapping. Major revisions include:

OFR55 Delaware Geological Survey Petrographic Data Viewer

Petrography is a branch of geoscience focused on the description and classification of rocks, primarily by microscopic study of optical properties of minerals. A thin sliver of rock is cut from a sample, mounted on a glass slide, ground to approximately 30 microns (0.03mm), and viewed under a microscope that uses polarized light. By observing the colors produced as plain polarized light and crossed (90 degrees) polarized light shines through the minerals, petrologists can determine the minerals that comprise the sampled rock.

Hands on geohydrology training for students

Date

About 30 students from Dr. Paul Imhoff’s Civil and Environmental Engineering Hydrogeology class were introduced to water level and water quality monitoring instruments and drilling equipment on March 21, 2019 at the DGS building.

A Sign of the Times

Date

Thanks to a University of Delaware (UD) signage initiative, the DGS now has new signs on the outside of our building.

New Instrumentation for Water Budget Evaluation

Date

The Delaware Environmental Observation System (DEOS) and the Delaware Geological Survey have recently acquired new instrumentation to measure evapotranspiration (ET). The purchase of an eddy covariance instrument, partially supported by the Department of Natural Resources and Environmental Control, will improve the ability to quantify ET during agricultural and water supply drought periods and improve water availability estimates for resource managers.

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.
