Understanding the resilience of barrier islands and coastal dunes after storms

E-Mail
When a coastline undergoes massive erosion, like a hurricane flattening a beach and its nearby environments, it has to rebuild itself - relying on the resilience of its natural coastal structures to begin piecing itself back together in a way that will allow it to survive the next large phenomena that comes its way.
Drs. Orencio Duran Vinent, assistant professor, and Ignacio Rodriguez-Iturbe, Distinguished University Professor and Wofford Cain Chair I Professor, in the Department of Ocean Engineering at Texas A&M University, are investigating the resilience of barrier islands and coastal dunes after high-water events and storms. In doing so, they are helping engineers and researchers assess the vulnerability of coastal landscapes. ....

Sea level rise up to four times global average for coastal communities

E-Mail
Coastal populations are experiencing relative sea-level rise up to four times faster than the global average - according to new research from the University of East Anglia.
A new study published today in
Nature Climate Change is the first to analyse global sea-level rise combined with measurements of sinking land.
The impact of subsidence combined with sea-level rise has until now been considered a local issue rather than a global one.
But the new study shows that coastal inhabitants are living with an average sea level rise of 7.8 mm - 9.9 mm per year over the past twenty years, compared with a global average rise of 2.6mm a year. ....

UNESCO reveals largest carbon stores found in Australian World Heritage Sites

E-Mail
Australia s marine World Heritage Sites are among the world s largest stores of carbon dioxide according to a new report from the United Nations, co-authored by an ECU marine science expert.
The UNESCO report found Australia s six marine World Heritage Sites hold 40 per cent of the estimated 5 billion tons of carbon dioxide stored in mangrove, seagrass and tidal marsh ecosystems within UNESCO sites.
The report quantifies the enormous amounts of so-called blue carbon absorbed and stored by those ecosystems across the world s 50 UNESCO marine World Heritage Sites.
Despite covering less than 1 per cent of the world s surface, blue carbon ecosystems are responsible for around half of the carbon dioxide absorbed by the world s oceans while it is estimated they absorb carbon dioxide at a rate about 30 times faster than rainforests. ....

ROV Making Incredibly Detailed Maps of Seafloor Off California

About 20 miles (32 kilometers) off the Californian coast, the 10,500-pound (4,7630-kilogram) remote submersible Doc Ricketts swept its strobe lights and sonar pulses across the seafloor like a transient silent disco. The vehicle wasn’t just putting on a show for the deep-sea denizens of the Pacific. It was mapping the terrain and ecology of a unique geological formation some 2,600 feet (793 meters) beneath the ocean’s surface.

Doc Ricketts was the tool by which a human team from the Monterey Bay Aquarium Research Institute scoured the seafloor, assessing its bathymetry and rich ecology.
“Our goal is to map benthic habitats at centimeter scale in complex terrain, in the deep ocean, efficiently,” said Dave Caress, a principal engineer for MBARI and the leader of the seafloor mapping team, in an email. “We can currently cover an area around [110 yards by 165 yards or 100 meters by 150 meters] in a single 10-hour ROV dive. ....

An exquisitely detailed global ocean model simulation from the National Center for Atmospheric Research (NCAR) has given scientists rare insight into where baby sea turtles may go in their lost years after they scramble off the sandy beaches where they are born and swim into the open ocean.
This look at a critically important period in the life cycle of endangered loggerhead turtles could help inform more comprehensive conservation efforts that encompass regions of the open ocean where young turtles grow, and not just the nesting beaches. It also pinpoints regions of the ocean that are important to study to better understand how to protect sea turtles. ....
