Harbormaster Don Beers installed a great white shark monitoring buoy near the 1st crossover (a generous donation from Bayside Marine). This buoy will detect sharks that are equipped with a tracking device, if it comes within 200 yards of the buoy. Buoys like this are being installed in the coastal waters of Massachusetts.
As you can see the buoy is yellow and at night a yellow strobe will be activated so boaters do not hit it. The strobe is not an indication there is a shark nearby.
Plymouth Harbormaster Chad Hunter, worked with Collin Batchelor and Ryan Culp, to deploy 3 receivers off Plymouth, MA . Each receiver can detect a white shark carrying an acoustic tag that swims within 200 yards of buoy.
Shark Safety Tips: If you see what you believe to be a shark in or near a swimming area, get out of the water and notify a Lifeguard, Harbormaster staff, or call 911. Seals are a major food source for great white sharks, do not swim within 300 yards of them. If you see seals in or near the swimming area the Harbormaster recommends you get out of the water and notify a Harbormaster or Lifeguard so the can monitor the area.
