Steve Hinnefeld, Indiana University Research by Indiana University geologists suggests that an intermediate amount of vegetation -- not too little and not too much -- is most effective at stabilizing freshwater river deltas. The study, "Optimum vegetation height and density for inorganic sedimentation in deltaic marshes," was published online Aug. 24 by Nature Geoscience. The findings may help guide restoration of river deltas, such as those near the mouth of the Mississippi River,...

Rapid advances in the new and developing field of restoration sedimentology will be needed to protect the world's river deltas from an array of threats, Indiana University Bloomington geologist Douglas A. Edmonds writes in the journal Nature Geoscience. The commentary, published this week in the November issue, addresses the fact that land is disappearing from river deltas at alarming rates. And deltas are extraordinarily important: They are ecologically rich and productive, and they are...

Scientists tracking wetland characteristics find potential good news The Gulf of Mexico: what role will the Mississippi River play in oil washing ashore and into delta wetlands? One of the spill's greatest environmental threats is to Louisiana's wetlands, scientists believe. But there may be good news ahead. Scientists affiliated with the National Center for Earth-surface Dynamics (NCED), a National Science Foundation (NSF) Science and Technology Center headquartered at the University of...

Water in Earth's critical zone; declining water resources in the U.S. west; "zebra stripes" in rock; dark energy under the sea-floor; undersea volcanic eruptions; Sumatra earthquake zone among topics Society stands at a crossroads. With growing problems such as resource depletion, energy sustainability, environmental degradation and climate change, can we protect the health of the planet while achieving widespread economic prosperity? This and other questions will be addressed at the fall...
