Item Historical Coastline Changes of Cape Henlopen, Delaware(Newark, DE: Delaware Geological Survey, University of Delaware, 2001) Ramsey, K.W.; Wang, L.T.Coastlines are not static features. They are shaped by the daily effects of wind, current, and wave activity. Over time, a coastline may move landward due to relative sea-level rise or low sediment supply, or seaward due to relative sea-level fall or an overabundance of sediment. Perhaps the most striking example of shoreline movement in Delaware is at Cape Henlopen which has grown northward approximately one mile in the last 160 years. Maps and aerial photographs show these changes.Item The Hurricane of October 21-24, 1878(Newark, DE: Delaware Geological Survey, University of Delaware, 2002) Ramsey, K.W.; Reilly, M.J.On October 21, 1878, a hurricane crossed the island of Cuba and headed east of Key West, Florida. On the evening of October 22, it made landfall north of Cape Lookout, North Carolina, as a low Category 2 hurricane with winds around 100 mph. The storm picked up speed after landfall and moved northward at a rate of greater than 40 mph and maintained tropical storm force wind speeds of greater than 60 mph with gusts much higher. On the morning of October 23, it passed up the west side of the Chesapeake Bay near the cities of Baltimore and Annapolis, Maryland, Wilmington, Delaware, and Philadelphia, Pennsylvania. By the late afternoon it had reached Albany, New York, and turned eastward and passed out to sea north of Boston, Massachusetts, on the morning of October 24.Item Instructions For Preparation Of Delaware Geological Survey Data Base Schedules(Newark, DE: Delaware Geological Survey, University of Delaware, 1984-01) Talley, J.H.; Windish, D.C.; Ramsey, K.W.This report contains the new DGS data schedules, describes the information that should be recorded on each schedule, and presents instructions for preparation of the schedules. The schedules are designed to make various kinds of data consistent with the input format screens utilized in the automated system.Item Physiographic Regions of the Delaware Atlantic Coast(Newark, DE: Delaware Geological Survey, University of Delaware, 2000) Ramsey, K.W.; Schenck, W.S.; Wang, L.T.Item Selected Geomorphic Features of Delaware(Newark, DE: Delaware Geological Survey, University of Delaware, 2000) Ramsey, K.W.; Schenck, W.S.; Wang, L.T.The shaded relief image on the left was created using 30-meter resolution Digital Elevation Models (DEMs). The DEMs were developed by John Mackenzie, University of Delaware College of Agriculture and Natural Resources Spatial Analysis Laboratory, from rasterized 1992-93 United States Geological Survey (USGS) Digital Line Graph (DLG) hypsography data. He also combined these data with zero-elevation contours extracted from 1989 Landsat TM Band 7 satellite imagery for coastal quadrangles. The image was digitally enhanced using a false sun angle of 45 degrees shining from the northwest to exaggerate the geomorphic features. In reality the Delaware Coastal Plain is not "mountainous," as it looks in this enhanced image. The hydrology layer was created using USGS 30 x 60 minute and 7.5 minute series DLG data. Municipal boundaries were created using the Delaware Municipal Boundary Framework Layer. Both maps are projected in Universal Transverse Mercator, Zone 18 (UTM 18) on the North American Datum 1983 (NAD83).
