Atlantic Shark Institute detects four great white sharks near Block Island

Block Island

NEW SHOREHAM, RI (WLNE) – The Atlantic Shark Institute announced Wednesday that they detected four great white sharks near Block Island.

The institute says the sharks were detected by their acoustic Shark Array receiver. The receiver picks up an acoustic ping that is sent out from the tags attached to sharks.

This is the second year the acoustic array has been in place and this most recent detection of the four sharks is the most significant finding to date, the institute says.

“We increased the number of acoustic receivers around Block Island from two in 2019 to seven this season and we assumed that this might be the result” shared Jon Dodd, Executive Director of the Atlantic Shark Institute. “This is just the second year in what will be a long-term study, so we are happy to be able to document and assess this activity in greater detail as we move forward with this important research.”

The four sharks ranged in size from a little more than 8 feet to the largest, a male, which was over 13 feet in length.

All the great whites that were detected had been tagged previously by Dr. Gregg Skomal from Massachusetts Division of Marine Fisheries, according to Dodd.

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.
