Hurricane Irma creates new island off Georgia coast: See it
Friday, January 19, 2018, 13:53 - When Hurricane Irma -- the fourth hurricane and second major hurricane of the 2017 Atlantic hurricane season – raked the U.S. Southeast coastline in September 2017, it not only inflicted millions of dollars in damage, it also created an island.
The new island was spotted off the Georgia coast. It formed when the storm – by then a tropical depression -- shifted the channel off Blackbeard Creek and took out part of a narrow finger of land that extended from Blackbeard Island south toward Sapelo Island, according to Marguerite Madden, head of the University of Georgia’s Center for Geospatial Studies, via Athens Banner-Herald.
An image taken by a drone on Sept. 28 (see below) confirmed the new islands existence. It measures at about 100 acres, according to estimates by Fred Hay, Sapelo Island manager for the state Department of Natural Resources’ Wildlife Resources Division.
Scientists fittingly dubbed the island Little Blackbeard, since it was formed from federally-owned and protected Blackbeard Island. Blackbeard Island itself is about 5,600 acres, and Sapelo is nearly 16,500 acres, the report added.

Because of the direction of currents off the Georgia coast, its coastal islands change continually, eroding on their north ends, building up on the southern ends, Hay told the Athens Banner-Herald. But a big force such as a hurricane can dramatically speed up that natural process, he explained.

But whether or not the island sticks around, remains to be seen.
“It’s really changing the currents coming in there,” Madden told the Athens Banner-Herald.
At recent Southern Forestry and Natural Resource Management GIS Conference in Athens, Madden told scientists that Little Blackbeard could eventually become part of Sapelo Island as movement continues with the new barrier island.
