GM25 Geologic Map of Offshore Delaware
Delineation of map units is based on sediment-core descriptions (e.g., texture, color, and composition) from 469 locations and seafloor morphology, which was assessed from a seamless NOAA/USGS topo-bathymetric model (Pendleton et al., 2014).
Delaware Geological Survey hosts the 110th Annual Meeting of the Association of American State Geologists
Date
The DGS hosted the 110th Annual Meeting of the Association of American State Geologists (AASG) at the Atlantic Sands Hotel & Conference Center in Rehoboth Beach, Delaware, from June 3-7, 2018.
Centralizing resources - Delaware Sea Grant researchers develop infrastructure to house flood, high water mark data
Date
University of Delaware researchers in the College of Earth, Ocean, and Environment are developing a centralized database and website to capture flood data in an effort to better understand and document the extent and severity of flooding in Delaware. In particular, the research team is focusing on data related to high water marks (HWM), the maximum level reached by the sea at high tide, or by a lake or river at its highest stand.
From where should beach replenishment sand come?
Date
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.

Kelvin Ramsey was quoted in the special section of Coastal Point, which featured the 50th anniversary of the Ash Wednesday 1962 nor'easter
DGS releases new geologic map of Rehoboth Beach area
Date
The Delaware Geological Survey (DGS) has published a new geologic map of the Rehoboth Beach area in eastern Sussex County entitled Geologic Map of the Fairmount and Rehoboth Beach Quadrangles, Delaware. Geologic Map 16 presents the results of research by Kelvin W. Ramsey of the DGS.
GM16 Geologic Map of the Fairmount and Rehoboth Beach Quadrangles, Delaware
The geologic history of the surficial units of the Fairmount and Rehoboth Beach 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 both onshore, in Rehoboth Bay, and offshore. Erosion during the late Pleistocene sea-level low stand and ongoing deposition offshore and in Rehoboth Bay during the Holocene rise in sea level represent the last of several cycles of erosion and deposition.
RI65 Wellhead Protection Area Delineations for the Lewes-Rehoboth Beach Area, Delaware
Water supply in the rapidly developing Lewes and Rehoboth Beach areas of coastal Sussex County in Delaware is provided by more than 80 individual public water wells and hundreds of domestic wells. Significant concerns exist about the future viability of the ground-water resource in light of contamination threats and loss of recharge areas. As part of Delaware's Source Water and Assessment Protection Program, wellhead protection areas (WHPAs) were delineated for the 15 largest public supply wells operated by three public water systems.
