Eastern Basins Oil and Gas Assessments

The USGS has conducted several assessments of undiscovered oil and gas in formations in the Blue Ridge Thrust Belt (5068), Piedmont Province (5069), Atlantic Coastal Plain Province (5070), and the New England Province (5072).  These basins are generally east of the Appalachian Basin Province (5067).

Natural Drought and Flood Histories from Lacustrine Archives

Previous work performed as part of the USGS Holocene Synthesis project illuminated complex centennial-scale patterns of drought and wetter-than-average conditions across the North American continent interior during the past two millennia, where paleorecord data coverage is sparse.  In order to explain the patterns of naturally-occurring drought, floods, and storms for the past, identified by...

Geological Investigations of the Neogene

More than a third of the United States population lives in counties directly on the shoreline, making them vulnerable to hazards associated with changing sea level and storm surges associated with hurricanes and severe storms. The geologic record contains many examples of past intervals of warm climate and high sea level. "Geological Investigation of the Neogene" is examining proxy records of...

    Flood-Inundation mapping in Georgia, North and South Carolina

    The U.S. Geological Survey (USGS) has created flood-inundation maps for selected streamgage sites in Georgia, North and South Carolina. These maps depict the approximate area that would be inundated at selected water levels, ranging from approximately top-of-bank to the maximum observed water level. The inundated areas depicted on these maps are approximate, and accuracy of the maps is a...
