The Discovery Channel’s Shark Week starts in just ten days! As ocean fans around the world gear up for the annual celebration of all things shark, New Englanders are turning their eyes to the North Atlantic Great white population. It seems these days Cape Cod beachgoers can’t help but scan the ocean horizon for a dorsal fin before taking a chilly but refreshing dip.
This year’s Cape Cod shark-spotting season kicked off on June 23rd when Captain Tyler Macallister captured video footage of a great white, Carchardon carcharias, six miles southwest of Provincetown, in Cape Cod Bay. Upon seeing the shark, Macallister began recording his calm and somewhat mystical encounter with the estimated 16-to-18 foot great white. A Massachusetts Division of Marine Fisheries biologist confirmed that the fish captured on Macallister’s video camera was a great white, but that the lack of scale in the footage meant its size could not be accurately determined.
Five days after Captain Macallister’s encounter with a great white shark in Cape Cod Bay, researchers from the Atlantic White Shark Conservancy saw a great white one-quarter of a mile off of Nauset Beach, near Orleans, Cape Cod. The researchers were able to identify the fish as a 12-to-14 feet long female great white and named her “Ping.” Ping was first spotted by a spotter plane and then tracked by boat. The Atlantic White Shark Conservancy sends out both a spotter plane and boat twice a week to study Ping and other great whites.
The increase in great white shark sightings has been going on for the last decade or so, and in the Cape Cod area it’s been partially attributed to the growing gray seal, Halichoerus grypus, population around the Cape. Gray seals were previously hunted by fishermen as a precaution towards preserving fish populations that the Gray seals consume, but the seals are presently protected by the Marine Mammal Protection Act of 1972. Great white sharks prey on seals and as seal populations expand in the Cape Cod area, there appears to be a growing number of white sharks.
If you are curious where these sharks spend their days, when they are not busy stalking Cape Cod’s massive seal populations, you can track tagged sharks through Ocearch.com or through the Ocearch app. And get ready for more information on New England’s sharks as we celebrate Shark Week here at New England Ocean Odyssey!
