May 29, 2019 — A Cape Cod company has proposed building a sonic barrier around the region’s beaches to chase away seals and prevent shark attacks.
Deep Blue LLC presented its idea Wednesday at a public meeting in Barnstable. It sparked a broader debate about addressing the region’s massive seal population.
The company envisions a system of underwater audio devices that will emit a sound unpleasant to seals.
Owners Willy Planinshek and Kevin McCarthy say that if the seals leave the area, the great white sharks that eat them will follow.
