Sea levels along the Southeast and Gulf coasts have been rapidly rising, reaching record-breaking rates over the past 12 years, according to a new study led by scientists at Tulane University. The research team detected rates of sea-level rise of about a half an inch per year since 2010.<\/p>\n\n\n\n

\u201cThese rapid rates are unprecedented over at least the 20th-century, and they have been three times higher than the global average over the same period,\u201d says S\u00f6nke Dangendorf, lead author, from the Department of River-Coastal Science and Engineering at Tulane.<\/p>\n\n\n\n

The authors studied a combination of field and satellite measurements since 1900, pinpointing the individual contributors to the acceleration.<\/p>\n\n\n\n

\u201cWe systematically investigated the different causes, such as vertical land motion, ice-mass loss, and air pressure, but none of them could sufficiently explain the recent rate,\u201d says Noah Hendricks, co-author and a student at Old Dominion University. \u201cInstead, we found that the acceleration is a widespread signal that extends from the coasts of the Gulf of Mexico up to Cape Hatteras in North Carolina and into the North Atlantic Ocean and Caribbean Seas, which is indicative for changes in the ocean\u2019s density and circulation.\u201d<\/p>\n\n\n\n

Over the past 12 years this entire area, known as the Subtropical Gyre, has been expanding primarily due to changing wind patterns and continued warming. Warmer water masses need more space and thus lead to a rise in sea level.<\/p>\n\n\n\n

The scientists conclude that the rates will likely return to the values predicted by climate models in the coming decades.<\/p>\n\n\n\n

\u201cHowever, this is no reason to give the all-clear,\u201d said Torbj\u00f6rn T\u00f6rnqvist, co-author, from the Department of Earth and Environmental Sciences at Tulane.<\/p>\n\n\n\n

\u201cThese high rates of sea-level rise have put even more stress on these vulnerable coastlines, particularly in Louisiana and Texas, where the land is also sinking rapidly.\u201d<\/p>\n\n\n\n
