Sand tiger sharks are one of the biggest reasons North Carolina wreck diving is so iconic.

But why do they “hover” over the wrecks like that?

Because of usually strong currents, this wreck is full of life ❤️! If you stay still, fishy come close and watch you in the eye (advantage of rebreathers 😉).

The wreck is covered with beautiful purple sea fans! Love the Mediterranean and can't wait to visit Croatia again!

There is nothing quite like being surrounded by dozens of sharks in the Graveyard of the Atlantic.

These sand tiger sharks patrol the North Carolina shipwrecks with an eerie, stealthy movement that is absolutely mesmerizing to watch up close.

Why Sand Tiger Sharks Hover on North Carolina Wrecks

Watching sand tiger sharks hover over North Carolina’s wrecks is one of those experiences that feels unreal—like the ocean slows down just long enough to show you how these animals truly move.

It took me years to line it up. Offshore wreck diving here isn’t guaranteed. You can plan everything perfectly, but the Atlantic has a mind of its own. The dive operators running these trips don’t gamble on marginal conditions—if there’s any doubt about weather, sea state, or visibility, they call it off.

I’ve had trips end before they started: days of forecast watching, crossed fingers, then the dreaded cancellation as storms roll through. It’s a brutal feeling after you’ve taken time off, traveled, and done all the prep. But that safety-first culture is part of what makes North Carolina one of the most respected dive regions on the East Coast. The captains here know the water, and they know when to wait.

So when the conditions finally align, it feels earned. Every minute on the wreck matters. After multiple canceled attempts, I finally got my shot.

North Carolina’s shipwrecks create the perfect habitat for sand tiger sharks to gather in large numbers. This stretch of coastline—known as the “Graveyard of the Atlantic”—offers countless structures for shelter, abundant prey, and the ideal temperature range these sharks need to thrive. It’s not uncommon to see dozens of sand tigers on a single dive, all coexisting peacefully in the same space.

This kind of consistency is rare globally, making these wrecks a world-class destination for shark encounters. The mix of accessible wrecks, clear summer visibility, and reliable shark populations draws divers, filmmakers, and researchers from around the world.

Why Scientists Think They Return

Photo-ID projects and scientific studies have confirmed that individual sand tiger sharks, especially females, return to the same wrecks month after month—and even across years. While researchers haven’t pinpointed one single reason for this site fidelity, several hypotheses keep surfacing:

Possible Explanations

• Reliable “rest stops” The wrecks may act like recurring waypoints where sharks can conserve energy between travel legs.
• Overwintering & seasonal residency Some sharks appear to use these offshore areas consistently across different seasons, not just as quick stopovers.
• Mating and reproduction Recent fieldwork suggests signs of mating behaviors and gestation-related habitat use in this region.
• The “oasis effect” Wrecks attract and concentrate marine life, creating dense food webs. Studies found that fish communities differ between wrecks with sharks and those without.

So while these wrecks might look like relics fading into the Atlantic, for sand tiger sharks they’re living, breathing ecosystems—critical habitats that meet their needs across feeding, migration, and reproduction cycles.

FAQs

Wrecks like U‑352 and the Bruse Reeb typically lie between 90–120 feet (27–37 m)—depths where Sand Tiger Sharks are frequently observed during dives.

The prime season for sightings is late summer through early fall (August–October) when warmer water and marine life activity increase.

No—Sand Tiger Sharks are generally docile toward divers, often exhibiting slow cruising behavior near structure; maintain respectful distance and avoid interaction.

Sharing a few photos from our recent Scapa trip!
The wrecks aren’t just fascinating on their own, they’re full of life too. Most are covered in colorful sea anemones, and we even spotted lobsters, velvet crabs, and lots more along the way.
It’s so cool to see these old ships slowly turning into underwater homes for so many creatures!

In the Shadow of a Wreck: Great Barracuda of North Carolina

The great barracuda (Sphyraena barracuda) is the largest of its kind in the Atlantic. While several smaller species exist, this is the only large predator divers are likely to encounter off North Carolina’s shipwrecks. Streamlined and built for speed, it is capable of bursts up to 36 mph (58 km/h). Reefs and wrecks provide perfect vantage points for ambush, where a barracuda can hold position with minimal effort before striking.

https://www.youtube.com/watch?v=IF3m5qy2WPA

Equipped with two rows of razor-sharp teeth, the great barracuda’s stillness can be deceiving. What appears to be calm hovering is, in fact, a hunter waiting for its next opportunity. Their strategy relies on patience, conserving energy until the perfect moment to launch a lightning-fast attack. Few prey escape once those jaws snap shut.

Vortex of Survival: Baitball Frenzy on a North Carolina Shipwreck

We launched with Atlantis Charters (trip organized by Gotham Divers) and headed east into open Atlantic Ocean. This corridor of wrecks concentrates life: currents stack plankton, baitfish ride the structure, and predators cruise the edges. The top of the deck was approximately 85 ft deep, allowing for slight variation. The main action was positioned between 60 and 80 ft.

https://www.youtube.com/watch?v=QmKtGsic3pY

The Hunt: How the Vortex Forms

At first, the baitfish flashed in loose silver sheets above the deck. The jacks pressed in from the perimeter. The school cinched into a sphere. Then, it formed a spiraling column—a living vortex—hovering just over the main deck. Strikes came from the flanks and below, using the flat steel as a base to pin the bait upward. The cycle repeated: circle, squeeze, break, reset.

Likely predators: jacks commonly seen on NC wrecks (e.g., greater amberjack or almaco jack).
Tactics observed: herding, pin-wheel circling, quick surge strikes from cover.

Why Wrecks Amplify Predation

• Structure = leverage. Flat deck and vertical faces constrain escape routes and keep the baitball suspended just above steel, where predators can tighten the circle.
• Eddies & seams. The wreck’s wake creates small eddies that hold plankton, drawing in baitfish and the jacks that hunt them.
• Refuge–trap effect. The wreck feels like shelter to small fish, so it concentrates bait over hard structure; predators use the same edges and flat deck to corner and compress the school—turning “refuge” into a trap (an ecological trap).

Camera & Lighting Setup

• Camera: Panasonic GH5
• Lens: 14–42mm kit zoom paired with Nauticam wet wide lens (for fast switches to true wide FOV)
• Lights: Bigblue video lights for clean fill on the baitball’s outer skin and to hold color on the wreck details
• Approach: I stayed low to avoid splitting the school. Just hooover on the main deck of the ship wreck

Dive Conditions & Safety Notes

• Run: ~1 hour offshore from Atlantic Beach, NC
• Depth: ~80 ft to the deck; mid-water action above the superstructure
• Exposure: 5 mm wetsuit was comfortable
• Awareness: Mind surge along hull edges; track gas and NDLs closely at this depth.

North Carolina Wreck Diving: The Bruse Reeb

North Carolina is often called the Graveyard of the Atlantic, home to hundreds of shipwrecks scattered along its coast. While the famous wrecks like the U-352 and the Spar get most of the attention, some of the most memorable dives come from the lesser-known sites hidden offshore.

https://youtu.be/wu43_h92tZA?si=uVu-PeLl8Nb3fNWb&t=581

On a recent trip with Gotham Divers, aboard Atlantis Charters out of Beaufort, NC, we headed out to a site nicknamed the Wreck of the Bruse Reeb – Bow Section. It’s not one of the marquee wrecks you’ll see in guidebooks, but that’s exactly what made the dive so interesting—quiet, atmospheric, and full of life.

Exploring the Wreckage

The bow section of the Bruse Reeb lies scattered across the seafloor, its remnants slowly being reclaimed by the ocean. Rusting beams and plates provide structure for schools of fish that weave through the wreckage. Though modest in scale compared to other North Carolina wrecks, it offered plenty of details to notice and film, making the dive feel like a mix of history and marine life.

Crossing Paths with Another Diver

Also on board that day was Squalus Marine Divers, who was filming the dive for his own channel. Around the 10-minute mark of his video, he was capturing footage of a perfectly camouflaged summer flounder when I drifted into the frame. Flounders are masters of disguise. You usually won’t notice them until they shift or flick their fins. It was a fun, unscripted moment to have both of us filming the same fish from different angles.

Why North Carolina Diving Stands Out

This dive was a reminder of what makes North Carolina wreck diving so special. Beyond the well-known sites, there are countless smaller wrecks scattered offshore, each with its own atmosphere and ecosystem. From Beaufort to Morehead City, operators like Atlantis Charters make these sites accessible, giving divers the chance to experience both the legends and the hidden gems of the Graveyard of the Atlantic.

To get a closer look at the wreck and the marine life around it, check out the full dive video from Squalus Marine Divers above. About ten minutes in, you’ll spot the moment when we both film the same summer flounder. This is one of those small, unscripted underwater encounters. Such experiences make dives like this so memorable.

End of A Dive – MV Shakem

The images below capture the final moments of our underwater odyssey through the haunting remains of the MV Shakem. This former cargo vessel was once a regular sight as it transported cement between Grenada and Trinidad. It met its fateful end, possibly due to being overloaded. Surrounded by myths of its heavily burdened hull, the Shakem ultimately surrendered to the depths of the sea.

Our Dive Master making sure everyone diving around the wreck remained safe.

Removing the safety line at the end of dive.

Waiting for divers to clear their safety stop at 15 feet.

I’m also waiting, but while I do, I’ll take the opportunity to capture a few photographs.

Remnants of War: SS Thistlegorm

SS Thistlegorm was a British cargo steamship built in 1940. It was sunk by German aircraft bombers in the Red Sea in 1941.

The ship rests underwater in the Ras Muhammad National Park at the southern extreme of the Sinai Peninsula. It overlooks the Gulf of Suez on the west and Gulf of Aqaba to the east.

The ship contained trucks, armored vehicles, motorcycles, guns, ammunition, radio equipment, boots, aircraft parts, railway wagons and two steam locomotives.

German aircraft dropped two 2.5-ton high-explosive bombs on Thistlegorm. Both of these bombs struck hold 4 near the stern of the ship in October 1941. The bomb exploded and ignited some of the ammunition stored in hold 4. This led to the sinking of Thistlegorm. The explosion caused the loss of four sailors and five defensively equipped merchant ship (DEMS) gunners.

In the early 1950s, Jacques Cousteau discovered the shipwreck by using information from local fishermen.

In the 1960’s, recreational diving began on the shipwreck. Today the SS Thistlegorm shipwreck hosts about 100 scuba divers per day.

Scuba Diving is the Best Way to Face Your Fears

How do you know if you’re truly living your life to the fullest? For some, it may be taking the plunge into underwater adventures with sharks and sea turtles. A scuba diving trip to a far off country like Egypt, Fiji, or Maldives might just be what it takes to face your fears, meet new people, and live boldly each day by pushing yourself out of your comfort zone.

Scuba Diving in the Open Ocean with Sea Creatures

Sharks, stingrays, octopus, and dolphins are just a few of the creatures you might encounter while scuba diving. If you’ve ever wanted to face your fears, now’s your chance! The first time I saw a shark off our dive boat was life-changing—I’m not even kidding. Being in complete awe of nature’s beauty alongside fellow open water divers made me feel like I could take on anything in life.

And if seeing a shark doesn’t do it for you, there are plenty of other reasons why it’s worth taking that next step out of your comfort zone by enrolling in a scuba course and dive into deeper waters:

• You’ll discover what living more boldly means for you personally.
• You’ll learn how to break through perceived limitations such as fear.
• You’ll meet new people who will challenge your thinking and push you to live more fully.

Living Fearlessly

Scuba diving can be one of the most exhilarating and liberating things you’ll ever do, and it offers a unique opportunity for you to face your fears head-on. Swimming through a shipwreck or undersea cave, surrounded by schools of colorful fish, it’s easy to understand why diving has become so popular. However, what many people don’t realize is that scuba diving also gives divers an opportunity to meet their fears in an incredibly safe way. If you have a phobia (or multiple) but want to get past them, make plans for an upcoming vacation trip: Naui / PADI / SDI certification courses are offered all over the world and there are plenty of dive resorts available everywhere from Gulf of Mexico to Indo Pacific. Whatever your fear may be — Closed spaces? Wildlife? Self-reliance? The dark? — scuba diving lets you face them while relying on a tank full of oxygen.

Why Do It?

Scuba diving offers a natural opportunity to confront fears and phobias. If you’re not comfortable in water, for example, learning how to swim and dive better can help you overcome those fears. Scuba diving also gives you a chance to observe sea life and other creatures that live under water. Some divers are able to see sharks or scuba dive at night, which allows them an adventure they wouldn’t have experienced otherwise. There are countless reasons why people choose scuba diving – maybe it’s new experiences like these you’re looking for as well?

Ending A Decade of Birthday Dives

Today is my birthday! I originally planned to be in the Philippines celebrating and scuba diving the Tubbataha Reefs Natural Park, a UNESCO World Heritage Site. Unfortunately, the COVID-19 pandemic has altered my magnificent birthday dive schedule this year. And it has also ended a decade of consecutive fantastic birthday dives.

Spending time out of the water has allowed me to reflect on the good times and how fortunate I have been. About seven years ago, I picked up underwater photography and later videography.

Here are a few images that have brought back a few fond memories of phenomenal scuba diving.
