New data suggests that the Mississippi Delta is still sinking, but at a much slower rate than previously estimated. A new paper published in the journal Earth and Planetary Science Letters reports these new findings. Geoscientists arrived at this new conclusion after comparing detailed sea-level reconstructions from different areas of coastal Louisiana. The new findings not only reveal new information about the subsidence of the Mississippi Delta, but also admonishes the continuous...

By David Malmquist, Virginia Institute of Marine Science A new study of local sea-level trends by researchers at the Virginia Institute of Marine Science (VIMS) brings both good and bad news to localities concerned with coastal inundation and flooding along the shores of Chesapeake Bay. Dr. John Boon, the study's lead author, says the good news is that "absolute sea level in Chesapeake Bay is rising only about half as fast as the global average rise rate." The bad news, says Boon, is that...

Researchers analyze decade's worth of GPS data for study A large section of northwestern Harris County "“ particularly the Jersey Village area "“ is sinking rapidly, according to a University of Houston (UH) geologist who has analyzed GPS data measuring ground elevation in the Houston area. Some points in Jersey Village are subsiding by up to 5.5 centimeters (about 2 inches) a year, said Shuhab Khan, an associate professor of geology at UH. Khan, along with UH geology professor...

Environmental scientists at the University of Pennsylvania and Durham University have employed a novel combination of geological and model reconstructions of wetland environments during a 10,000-year period to address spatial variations in sea-level history and provide quantitative estimates of subsidence along the east coast of England. The findings indicate that glacial rebound "” the rise or fall of land masses that were depressed by the huge weight of ice sheets during the last...

An international team of environmental scientists led by the University of Pennsylvania has shown that sea-level rise along the Atlantic Coast of the United States was 2 millimeters faster in the 20th century than at any time in the past 4,000 years. Sea-level rise prior to the 20th century is attributed to coastal subsidence. Put simply, land is being lost to subsidence as the earth continues to rise in response to the removal of the huge weight of ice sheets during the last glacial period....

The 'Coastland Map' produced by scientists from Durham University and published in the Journal GSA Today, charts the post Ice-Age tilt of the UK and Ireland and current relative sea-level changes. According to the map, the sinking effect in the south could add between 10 and 33 per cent to the projected sea-level rises caused by global warming over the next century. * The projections are less than previous estimations for subsidence and could help local authorities to save money on sea and...
