The Not-So-Mysterious Loss of Salt Marshes and Ecosystem Services
Thursday, 28 March 2013 00:00

By Paige Brown – Scientific American Blog – March 12, 2013

Healthy salt marsh creeks at Plum Island Estuary, Massachusetts, are lined with lush, smooth cordgrass. The plant’s below-ground roots and above-ground leaves build and maintain salt marshes. However, global climate change and sea level rise, agricultural and industrial development and loss of sediment supply are contributing to dramatic rates of wetland loss worldwide. In the Gulf Coast region, these and other factors – many still largely under-studied – are driving salt marsh loss at unprecedented rates. While salt marches are famously valued for their function in nutrient removal, improving water quality by filtering runoff and removing sediment, nutrients, pesticides, metals, and other pollutants [3], new research suggests that these marshes are not impervious to the damaging effects of natural and artificial nutrient accumulation.

DE: Join DENIN, partners in guided trip to St. Jones Reserve in Kent County
Thursday, 28 March 2013 00:00

University of Delaware –  March 22, 2013

A component of the Delaware National Estuarine Research Reserve (DNERR), the St. Jones Reserve includes about 3,750 acres of tidal brackish-water and salt marshes, wooded fringe habitat, farmlands and meadows distributed along the lower St. Jones River. The St. Jones watershed drains a portion of central Kent County, including the city of Dover, and empties into Delaware Bay. For full story, click here.

 
Britain Haunted by Risk of Flooding
Thursday, 28 March 2013 00:00

New York Times –  March 21, 2013

Britons are used to griping about the rain, but a series of major floods in recent years has prompted some to ask how ready the nation is to cope with the rising sea levels and increase in storms that are expected to come as the climate warms. In some places, the authorities have chosen to let the sea retake uninhabited areas, hoping new wetlands will provide a natural barrier and ease pressure on populated zones. On the Blackwater estuary in southeast England, for example, sea walls were broken down in 2002 to let a former farm become salt marsh. As well as cutting flood risk, the local Essex Wildlife Trust said the new wetlands provide a home to wading birds, 14 kinds of fish and plant species like sea lavender.

On March 11, the Natural Resources and Habitat Working Group reported updates in ongoing studies of the impacts of sea-level rise on salt marshes. Data are confirming that sea-level rise is happening three to four times faster in Rhode Island and the Northeast than the global average, according to the group. For full story, click here

 
Artists Propose Stemming Tide Of Global Warming With Artificial Marshes

“Extreme sea level rise combined with extreme shore level rise to make these hundred-year [storm] events become more frequent,” Marsching says. Salt marshes, she says, are “essentially big sponges that slow down the water.” From Chelsea to Quincy, “it’s almost all hard. Once upon a time it was all tidal flats and salt marshes, which were filled in over the years. [Our project] is bringing back these natural adaptive measures.” For full story, click here.

 
TX: Expert: Sea level rise in Texas will get worse without action
Thursday, 28 March 2013 00:00

Your Huston News –  March 13, 2013

Sea-level rise is not the type of looming coastal natural hazard that announces itself with the roaring bravado of a hurricane, but it is there, in the details of the storm, and will only get worse in the absence of public sentiment to address the issue, says a Texas A&M University researcher and one of the state’s leading coastal development experts. “We stand to lose a very large amount of one of our most productive environments in all of Texas — the coastal salt marsh,” Jacob says. “All of our significant fisheries depend in one way or another on this environment. As sea level rises, marshes can migrate inland if the land is available, but there are many places on the coast lined with sharp rises or bluffs. In these areas marshes will drown as water rises. Much of the remaining areas are becoming urbanized with shoreline protection that will also hinder marsh migration.” For full story, click here.


 
MA: NOVA Scientist and Award-Winning Author Joins Great Freedom Adventures’ Eco-Bike Tour on the MA North Shore to Show Recent Storm Damage, Erosion and Collapse of Homes on Plum Island
Thursday, 28 March 2013 00:00

PRWeb –  March 12, 2013

NOVA scientist Bill Sargent will show Great Freedom Adventures’ bike tour guests first-hand, the devastation to Plum Island, MA homes and shoreline by recent storm surges. Several homes have collapsed into the ocean and more are slated to be razed because they are no longer safe to inhabit. Sargent, an award-winning author of eight books on science, the environment and sea-level rise, will share with spring and fall Salt Marsh and Songbirds Eco-Bike Adventure participants, the ever-changing nature of barrier islands, beach erosion and the threat to the New England coastline from rising sea levels.
