The way in which buildings, roads, parking lots and other components of the built environment are integrated into communities impact a wide range of biogeochemical and hydrological processes. Among other effects, increased pollution discharge into streams has significant implications for the health of ecosystems. Scientists at the Woods Hole Research Center have developed new high resolution maps of the built environment , expressed in terms of impervious surface cover, for the 168,000-square-kilometer Chesapeake Bay watershed, a region that has been highly altered by human land use.
According to Scott Goetz, a senior scientist at the Woods Hole Research Center and lead author of an article in the current edition of Eos describing the work, "The information captured in these maps can be used to help mitigate impacts associated with the impervious nature of built environments, including reduced water quality, impoverished stream biota, and increased flood risk."
The new maps were developed for the region at 30-square-meter spatial resolution, and are currently being used for baseline monitoring and modeling activities in the Chesapeake Bay Program restoration effort. The Eos article focuses on use of the regional maps to assess the quality of a new national impervious cover map available at coarser (one-square-kilometer) resolution for the entire conterminous United States.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
