Sea Level Rise and Sinking Land|
December 12, 2013 | USGS
“Communities and coastal habitats in the southern Chesapeake Bay region face increased flooding because, as seawater levels are rising in the bay, the land surface is also sinking. A USGS report concludes that intensive groundwater withdrawals are a major cause of the sinking land, or ‘land subsidence’, that contributes to flooding risks in the region.” Quoted from the USGS press release.

Since 1972 the “Roadside Geology” series has provided introductory information on the geology of states and small regions of the United States.
The books provide a combination of maps, travel logs, photos and commentary for the geology that can be seen along highways or visited at parks and public viewing areas. They are popular with geologists, teachers, students and others who are interested in the Earth.
Ancient Seawater Under Chesapeake Bay?|
November 14, 2013 | USGS
“USGS scientists have determined that high-salinity groundwater found more than 1,000 meters (0.6 mi.) deep under the Chesapeake Bay is actually remnant water from the Early Cretaceous North Atlantic Sea and is probably 100-145 million years old. This is the oldest sizeable body of seawater to be identified worldwide.” Quoted from the USGS press release.
Slow Moving Groundwater Delays Water Quality Actions|

New research by the USGS indicates it may take several decades for many water-quality management practices aimed at reducing nitrogen input to Chesapeake Bay to achieve their full benefit due to the influence of groundwater.
Partial Solar Eclipse Visible on Sunday Morning from the East Coast|
November 1, 2013 | NASA
“The final event of 2013 is the most interesting eclipse of the year. It is one of the rare hybrid or annular/total eclipses in which some sections of the path are annular while other parts are total. The duality comes about when the vertex of the Moon’s umbral shadow pierces Earth’s surface at some locations, but falls short of the planet along other sections of the path.” Quoted from the NASA website.
People as far west as Pittsburgh should be able to see the eclipse. Observing from the east coast.

September 19, 2013 | National Science Foundation
The geographic distribution of scientists and engineers in the United States is not uniform. Some states have much higher percentages of these professionals than other states. Virginia, Washington, Maryland and Colorado have higher than average numbers of these professionals. Arkansas, Kentucky, Louisiana, Mississippi, North Dakota and South Dakota have lower percentages.
