DGS has released a new dataset “The Determination of Total Nutrient Loads from the Nanticoke Watershed above the USGS Nanticoke River near Bridgeville Gauging Site (01487000) from Data Provided by an Automated Nutrient Analyzer “.
DGS staff member Scott Andres is a co-author on a paper “ASSESSING COASTAL PLAIN RISK INDICES FOR SUBSURFACE PHOSPHORUS LOSS" that was recently published in a special issue of the Journal of Environmental Quality.
DGS staff member A. Scott Andres made a presentation “Results of selected UD nutrient monitoring projects in the Nanticoke River watershed” at the inter-agency meeting Chesapeake basin water quality data, trends, and interpretations held August 11, 2016 at the Delaware Department of Agriculture in Dover.
Scott Andres presented an invited talk “Update on Groundwater Monitoring in Delaware” at the Groundwater Management Workshop sponsored by the Delaware River Basin Commission (DRBC) in West Trenton, NJ on October 22, 2015.
Environmental Sciences student James Hanes (BS 2016) has accepted a Water Resources Center Undergraduate Internship for Fall 2015 to work with A. Scott Andres of DGS, and William Ullman and Christopher Main of the School of Marine Science and Policy at the University of Delaware. James will work on high-frequency environmental data collected by the North East Water Resources Network (NEWRNet) project (http://www.dgs.udel.edu/projects/newrnet-north-east-water-resources-net…), an NSF-EPSCoR funded project that includes investigators and students from the Universities of Delaware, Rhode Island, and Vermont.
Three University of Delaware scientists are studying tidal water flow and sediment movement in a Kent County salt marsh to better understand changes to the marsh ecosystem due to a rising sea level.
On a small, homemade barge, built from the skeleton of an old ship, a gray slurry of bay bottom sand flows out, of a pipe into a bucket. Two scientists, a well driller and two student interns drill a hole in the floor of the Indian River Bay. They'll install a very long pipe into the hole and use it to monitor groundwater - how much flows 'into the bay, how salty it is and how many nutrients it carries with it.
Scott Andres of the Delaware Geological Survey and Holly Michael, assistant professor of geological sciences, participated in 2011 National Ground Water Association (NGWA) Groundwater Summit and were co-organizers of the session titled "Submarine Discharge of Groundwater and Nutrients into Estuaries and Oceans," May 3, Baltimore.
This report provides initial research results of a storm-water and base-flow sampling and analysis project conducted by the University of Delaware College of Marine Studies (CMS) and the Delaware Geological Survey (DGS). Base-flow samples were collected from six tributary watersheds of Delawareâs Inland Bays on 29 occasions from October 1998 to May 2000. Water samples were filtered in the field to separate dissolved nutrients for subsequent analysis, and a separate sample was collected and returned to the laboratory for particulate nutrient determinations.
