Scientists at the Woods Hole Research Center in Maine say they've created a satellite map to show the Chesapeake Bay area's urban development.
The researchers say the manner in which buildings, roads, parking lots and other components of a built environment are integrated into communities impact a wide range of biogeochemical and hydrological processes.
The high resolution maps of the 64,000-square-mile Chesapeake Bay watershed show the region has been highly altered by human land use.
"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," said Scott Goetz, a senior scientist at the center and lead author of the research.
"These maps provide a unique view of the extent and intensity of the built environment, and the urbanization process which continues to rapidly evolve as exurban development expands into traditionally more rural areas," he added.
The project is detailed in the current edition of the journal Eos.

Healthy coastal wetlands would adapt to rising oceans
Tidal marshes, which nurture marine life and reduce storm damage along many coastlines, should be able to adjust to rising sea levels and avoid being inundated and lost, if their vegetation isn't damaged and their supplies of upstream sediment aren't reduced, a new Duke University study suggests.

Researchers identify gene linked to common ailment in labrador retrievers
Researchers at the University of Minnesota College of Veterinary Medicine have identified a gene in Labrador retriever dogs highly associated with the syndrome of exercise-induced collapse (EIC). After intense hunting or retrieving exercise, activities these dogs are trained to perform, affected Labradors start to lose control of their hind limbs. In most cases, their legs get wobbly and the limbs give out, and in rare cases the dogs may die. Labradors are the most common dog breed in the world and an estimated 3-5 percent of Labradors have this condition. The research is published in the journal Nature Genetics.
Archaeology at Smuttynose reveals fate of fisheries
(PhysOrg.com) -- The name Smuttynose Island may recall the infamous 1873 ax murders or even Smuttynose Craft Beer, made in Portsmouth, N.H. But the island, one of the Isles of Shoals six miles off the Maine and New Hampshire coast, boasts a rich history of North Atlantic fisheries dating back to European settlement in the early 1600s.
