Great White Sharks Migrate Past the Outer Banks

We’ve seen a couple of headline in the past two weeks about how Great White Sharks are swarming to the waters off the Outer Banks. It’s based on the tagged sharks that OCEARCH has been tracking.

OCEARCH is an oceanographic research organization that tags a number of species, including whales and tiger sharks, but the great white sharks are the attention getters.

What’s happening off the Outer Banks coast—and yes there are great white sharks there—are two factors coming together.

First of all, great white sharks have always been off the coast of North Carolina and at this time of the year they are more numerous. The reason is simple. They’re migrating, swimming from the cold waters off Canada to the warmer waters of Florida and even into the Caribbean.

The reason they seem so suddenly numerous is that OCEARCH has been continually tagging great white sharks off Nova Scotia for the past few years, there are more than every tagged, so more than every ping when they come to the surface.

What is happening is a very natural part of the Atlantic Ocean ecosystem.

For the most part, great whites stay at least a few miles off shore. Not always. There have been a few instances where a shark will send a signal from one of the Outer Banks sounds—usually Pamlico.

There was recently a false ping—not sure how that happened—placing Cabot, a 533 pound great white almost in the Pamlico River.

That would have been remarkable. Great white sharks cannot survive in fresh water and that far from Oregon Inlet, or any inlet, the water is considered fresh. But as it turns out, it was a false reading. 

Cabot sent a good strong signal from just south of Oregon Inlet, in the ocean, to set things straight.

The Outer Banks environment is fascinating. Plan your stay with Joe Lamb, Jr. & Associates to learn about the beauty of the Outer Banks.

Whales, Sharks Swim Past Outer Banks

It’s migration time out in the Atlantic Ocean off the Outer Banks. We had some whales—probably humpback—feeding within 100 yards of the Kitty Hawk shoreline on Monday. Over the weekend, three tagged great white sharks pinged a few miles off the coast.

it’s a typical pattern of life in the sea. There’s a tendency to think of sea life as relatively stationary, living in one area for their lifespan

That however, is not the case. Many, if not most, species of fish and mammals that live in the ocean are migratory.

Humpback whales migrate in the winter to the Caribbean to mate and give birth. That’s a two migration cycle. The humpback whale gestation period is 11 months so females breed one year, returning the following year to give birth.

The whales seen off the Outer Banks coast at this time of the year, are returning to Maine, where scientist have determined most of the East Coast humpback whales live.

The sharks that pinged offshore were tagged by OCEARCH, an organization that has has made a science of studying and tracking sharks The shark names are  Jefferson, Cabot and Hal, All three were tagged in 2018 off Nova Scotia.

Like humpback whales, great white sharks are highly migratory. Although they have some ability to withstand cold temperatures and water, they are a cold blooded species and prefer warmer waters—which is why they left Nova Scotia and headed south.

As ocean temperatures rise, they head north to the fertile feeding grounds off the Canadian maritimes.

The sharks are all male and range in size from 9’8” to 12’7”.
