By CNRS – YubaNet.com – May 12, 2012The area of the globe covered by wetlands (swamps, marshes, lakes, etc.) has dropped by 6% in fifteen years. This decline is particularly severe in tropical and subtropical regions, and in areas that have experienced the largest increases in population in recent decades. These are the conclusions of a studyconducted by CNRS and IRD researchers from the Laboratoire d'étude du rayonnement et de la matière en astrophysique (CNRS / Observatoire de Paris / UPMC / Université de Cergy-Pontoise / ENS), Laboratoire d'études en géophysique et océanographie spatiales (CNRS / IRD / CNES / Université Toulouse III-Paul Sabatier) and the start-up Estellus(1). To obtain these results, the scientists performed the first worldwide mapping of the wetlands and their temporal dynamics, for the years 1993 to 2007. This study, which has just been published in the journal Geophysical Research Letters, emphasizes the impact of population pressure on water cycles. For full story, click here.

Contact: Katherine Unger Baillie– Penn News – May 10, 2012Research by a trio of geoscientists, including the University of Pennsylvania’s Douglas Jerolmack, now offers an explanation for why some of the oil stayed out at sea. Using publicly available datasets, their study reveals that the force of the Mississippi River emptying into the Gulf of Mexico created mounds of fresh water which pushed the oil slick off shore. […] “We recognized that there was a very persistent mound, a bump or a bulge, in the elevation of the sea surface in the vicinity of the Mississippi Delta,” Jerolmack said. The reason was that the oil spill coincided with the typical spring flood on the Mississippi, creating a larger-than-normal flow of water into the Delta. This powerful discharge of fresh water mounded on top of the denser salt water of the Gulf. The resulting bulge, which was approximately 10 centimeters higher than the surrounding ocean and 50-100 kilometers in diameter, was positioned so that oil from the Deepwater Horizon drilling rig ran “downhill” and away from the coast.

NOAA Coastal Services Center
NOAA’s Digital Coast Website offers a collection of tools and resources that can be useful for various aspects of a community’s risk assessment. Most of these tools and resources are briefly introduced during the Roadmap for Adapting to Coastal Risk training. Some tools currently available include sea level rise tools for CT, GreenSeams (a flood management program), a NOAA Roadmap training presentation, example assessment maps and other tools for climate change adaptation in coastal areas.
