The geologic history of the surficial units of the Bethany Beach and Assawoman Bay Quadrangles is that 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 onshore, in Indian River Bay and Assawoman Bay, and offshore in the Atlantic Ocean.
4:37 p.m., Oct. 31, 2012--The Office of the State Climatologist and the Delaware Geological Survey (DGS), both based at the University of Delaware, provided the Delaware Emergency Management Agency (DEMA) and the National Weather Service with weather, coastal flooding and stream flooding information for Delaware during Hurricane Sandy.
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.
Beach-loving kids can follow their fascination with the sea to Coast Day on Oct. 7 from 11 a.m. to 5 p.m. at the University of Delaware’s Hugh R. Sharp Campus in Lewes. The family-friendly event features fun activities that tap children’s natural curiosity about the ocean.
“This year’s theme is ‘Checking in on Our Coast,’” said event chair John Ewart of Delaware Sea Grant, which presents the event with UD’s College of Earth, Ocean, and Environment. “Kids can use their senses to explore marine science — and check out the tools our researchers use to do so, too.”
The complex geologic history of the surficial units of the Harbeson Quadrangle is one of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to sea-level fluctuations during the Pleistocene. The geology is further complicated by periglacial activity that produced dune deposits and Carolina Bays scattered throughout the map area.
