The Atlantic Shark Institute announced Wednesday that it has detected four great white sharks in the waters off Block Island.
The institute discovered the sharks using an array of seven acoustics receivers set up as part of a long-term study of shark activity near the island, according to Jon Dodd, executive director of the institute.
The four great white sharks ranged in size from a little more than 8 feet to more than 13 feet.
The sharks had been tagged between 2015 and 2019 by Greg Skomal, of the Massachusetts Division of Marine Fisheries.
The acoustic receivers detected a ping that the tags send out.
The sharks were detected at the Block Island Wind Farm, the Southwest Ledge, the Southeast Corner of Block Island, and on the West Side of the Island.
