Coming up next on Jonathan Bird's Blue World, Jonathan helps archaeologists excavate Blackbeard

Hi, I'm Jonathan Bird and welcome to my world!

Arggg! I be Blackbird the pirate, and welcome to me…barge?

How I ended up a pirate on a barge is an interesting story! It all started back in 1717, when Edward

Teach, better known as Blackbeard the Pirate, was roaming the Atlantic from Africa to the

Caribbean, plundering ships as he went. Although reported by his crew to be a fair and decent

man, Blackbeard had a fierce reputation, partly due to his clever use of lit fuses in his

Off the island of Saint Vincent, Blackbeard and his crew captured a French merchant vessel

and quickly converted it to a pirate ship with 40 cannons, renaming her the Queen Anne’s

Revenge. She was Blackbeard’s flagship in a growing armada of captured ships.

But in 1718, Blackbeard ran the Queen Anne’s Revenge aground on a sand bar outside Beaufort,

North Carolina. Experts believe the grounding was intentional-the pirate version of corporate

downsizing. He stranded many of his crew and fled in a smaller ship. Latter that year,

Blackbeard was killed in a battle with British forces not far away at Okracoke Island.

The Queen Anne’s Revenge was lost for hundreds of years until being discovered in 1996.

The shipwreck is now an active underwater archaeological site administered by the North

Carolina Department of Cultural Resources. And that’s where I come into the story.

It’s nearly morning in Beaufort, North Carolina and I’m getting on a barge--with a team

of archaeologists. But not just any archaeologists! These are underwater archaeologists who are

excavating the wreck of Queen Anne’s Revenge.

My good friend Rick Allen is in charge of all cinematography that takes place on the

site and today he will be my underwater cameraman.

Everyone sets up their gear and it’s time shove off for the pirate adventures on the

As we head out under draw bridges making our way from the inlet to the open ocean, Wendy

Welsh, the project director prepares for the day’s work. It’s going to be a long day

as the weather has been bad, and the team has lost a lot of time this week. So we have

Wendy talks with nautical archaeologist David Moore, whose research original helped pinpoint

Soon we arrive at the wreck site, and the barge is anchored directly above it.

Alright, it’s been a while sine we have been out here so we’ve got some work to

do today so I hope you guys are ready to go. The way we left the site was, we have both

of our big dredges, they are laying on seventy stake, which is what our double buoys are,

and then we have our frames that are on the pile. What I want to do first is get two divers

in and kind of do a site assessment, see what’s going on…

The first team suits up to check on the wreck and visibility. The water is not known for

clarity here in this shallow, sandy area.

The archaeological team needs to be able to talk to each other underwater so they can

get things done, so they’re all wearing these full-face masks, which have communications

gear in them. You can talk by pushing this button, and you can hear what other people

are saying through this little earpiece. So I’m going to be wearing one too, I’ll

be able to talk to everybody, and hear what they’re saying!

We’ll get in, go to the bottom, get comfortable and follow the hoses down…

Rick and I have a quick discussion about out dive plan and then it’s time to see this

Jonathan, Jonathan, this is topside for a comm check.

The visibility on the bottom is terrible! I can barely see 4 feet! It’s hard to describe

how difficult it is to do the work in such bad conditions!

Eventually I find my way to one of the only landmarks on the wreck.

This is the north anchor, the largest anchor on Blackbeard’s ship. It’s about 13 feet

Soon the crew fires up the pumps on what is essentially a big vacuum cleaner, called a

Down on the bottom, this equipment is used to clear sections of the wreck by vacuuming

I’m using the vacuum to clear an area around an object, but I have no idea what the object

I’m not sure. It might be part of a cannon.

To me, everything we uncover looks like a rock. But to an expert, these concretions,

While most of the wood on a shipwreck is consumed by the sea; metal, glass and ceramics often

survive. But hundreds of years of marine growth like barnacles and oysters add layer after

layer of concretions on the artifacts. It takes an expert eye to identify artifacts

Up on deck, the water and sand from the dredge go through a sluice where larger objects are

sieved out, and heavier particles settle out. There’s all kind of good stuff in here that

Down on the bottom, I know we’re digging out something big.

What are we digging out here, is this a cannon?

This is an anchor. There should be a cannon right next to it, a little deeper buried down.

Wendy has joined us in the water and enlists my help to take some electrical readings.

The cannons, which are made of iron, produce a tiny electrical current as they corrode.

Wendy wants to measure the voltage they are producing as a way of learning how fast the

corrosion is taking place, and which cannons should be excavated first.

Our first step is to gently drill a hole through the marine growth on cannon to reach the metal.

Jonathan is holding the electrode. You can start the two minutes and let him know when

Copy that Wendy, starting the two minutes now.

Okay, start the reading on the concretion for C7.

I have to hold the probe on the cannon for two minutes to allow the reading to stabilize.

Then they record the reading up on the barge.

After doing that for an hour, I feel like a real archaeologist! I’m a regular underwater

But soon my tank is getting low and it’s time to go back to the surface.

You know, normally I’m not a fan of vacuuming, but vacuuming a cannon out of a shipwreck

Yeah, but I got a lot of sand in my gloves! That was great!

After a long day at sea, we finally turn and head back to the dock. But my work is far
