Real-time buoys to be placed off 3 beaches.
WELLFLEET — With little fanfare, shark detection technology on Cape Cod took a small step forward last weekend off Newcomb Hollow Beach, the site of last year’s fatal shark attack on bodyboarder Arthur Medici.
Cape Cod and regional public safety officials have been hoping for years to employ a kind of souped-up version of what they already have, an acoustic receiver attached to a buoy that can not only detect signals from tagged great white sharks but relay an instantaneous alert to lifeguards and beach administrators.
One such device was deployed off Newcomb Hollow on Saturday, state shark researcher Gregory Skomal said, and two more will be placed offshore next week, one at Head of the Meadow Beach in Truro and the other at Nauset Beach in Orleans
A total of 171 sharks have been tagged since 2009 with acoustic devices that broadcast a unique identifying signal that is picked up by a necklace of receivers attached to buoys off popular Cape beaches. The distance at which the receivers can detect shark signals depends on water clarity and other factors affecting underwater sound transmission, such as wave noise and vessel traffic, but Skomal estimates a shark passing within 330 to 660 feet of the buoy would be detected.
Wellfleet Beach Administrator Suzanne Grout Thomas said they were connected to the system Tuesday with email alerts about three sharks sent to her and to head lifeguards at town beaches. Skomal said towns would have to determine for themselves whether an alert merited closing a beach to swimming. Thomas said a shark detected in 20 feet of water, even at 300 feet from shore, could make it to shore fairly quickly and would result in a beach closure, ......

Sharks are not going anywhere. That is correct. They are just going where their food is. The food being the Grey Seal.
As the population of seals has increased, so has the size, frequency, population of great white sharks.
Sharks occasionally mistake a human swimming in the ocean for a seal. Especially, those short surf boards. So, they attack from below and take a bite. OOPS! Not a seal. So, Sorry. I did not mean to bite through that artery in your leg.
There was a guy on TV the night after the last shark fatality up in ME. He stated that IF Wet suits were not all black, like if they had stripes, the sharks would not occasional mistake a human for a seal. So, why are all neoprene wets suits black?
They're not...............
The red ones look like the suits the bad guys wore in the James Bond movie “Thunderball”.
I think sharks see black and white. I believe you would need stripes to not appear as just lighter shades of gray.
If the Real Time Shark Buoys on certain Cape Cod beaches keep cranking out Tagged shark ping alerts , I would expect many bathers to go swimming elsewhere.
Below, it has just started for today and more than likely will continue all day, everyday until the end of October. -Tom
MA Sharks 🦈 @MA_Sharks · 27m SHARK ALERT‼️ Newcomb Hollow, Wellfleet. Water closed to swimming until 10:10 following pings from two sharks.
Many years ago, before the Age of the Internet, I saw a documentary on sharks that had a shark in a long pool swimming from one end to the other.
A pair of electrodes were put in the pool near the middle.
A very low level electric current was then introduced between the electrodes and the shark would not cross the line.
Seems to me that a string of buoys could be set up that ran on solar energy and could produce a current between them as a shark deterrent..................
Maybe the governments of the MA coastal towns will have to put up shark nets like they have in other parts of the world.
There was a show on during the most recent shark week where a diver had a instrument that put out an electric current.
This was somewhere in the Bahamas. They were feeding the sharks to attract the Hammerheads and Bull Sharks. As soon as they turned on this electrode the sharks would come up and turn away immediately. It was pretty impressive how it worked. Apparently, the Hammerheads and Bull sharks have much more electronic receptors in their nose than others.
