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

  • The Pirate's shipwreck!

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

  • Arggg! I be Blackbird the pirate, and welcome to mebarge?

  • 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

  • hat to intimidate his enemies.

  • 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

  • high seas!

  • 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

  • a lot of scuba tanks.

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

  • the location of the wreck.

  • If you can get it Rick, take it up!

  • 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 weve 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 theyre 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 theyre saying!

  • Well 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

  • wreck for myself.

  • Woo! Ready?

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

  • I hear ya loud and clear!

  • Copy that, thank you Jonathan.

  • 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

  • long--that’s as big as a car!

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

  • dredge.

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

  • up the sand the continually accumulates.

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

  • is.

  • What is this?

  • 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,

  • as they are called, are treasure.

  • 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

  • in these rock-like concretions.

  • 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

  • well go through later.

  • Down on the bottom, I know were 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.

  • Then I apply an electrode.

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

  • it is complete.

  • 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

  • Indiana Jones!

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

  • Wow!

  • What’d you think of that?

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

  • is really fun!

  • Isn’t that neat?

  • 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

  • from done.

  • My next stop is the QAR field lab, where archaeologist Lisa Briggs is panning for treasure.

  • Hi Lisa!

  • Hey Jonathan, welcome. Come on in, this is our field lab. This is where we are doing

  • the micro artifact extraction.

  • At the field lab, Lisa is looking through all that sand and sediment we collected in

  • the sluice for micro-artifacts.

  • We find all sorts of tiny little artifacts that would be overlooked if we were to look

  • on site or underwater. It’s really difficult to identify things perfectly underwater. Weve

  • got low visibility, lots of currents, lots of stuff going on when we are actually underwater,

  • so we save all the sediment, we bring it back here and then we process it to try to find

  • the tiny little cool bits of treasure that we missed when we are actually physically

  • digging underwater.

  • The most common micro-artifact on the wreck is lead shot--tiny lead balls that would have

  • been ammunition for muskets.

  • Some of the shot that we find was actually used in hand-help muskets and smaller hand-held

  • firearms, and then some other shot that were finding even the very small pieces, grape

  • shot or seed shot, would have been used in bags inside of cannons. And that was used

  • mostly to try to take out the rigging of an enemy’s ship.

  • Lisa gives me a lesson in panning through the sand to separate the heavier lead from

  • the lighter sand and rocks. It’s a very similar technique to panning for gold.

  • You know, if it doesn’t work out, as an underwater archaeologist, I can go gold prospecting

  • after working on this site.

  • Were going to find you in Alaska next year?

  • Oh yeah!

  • Actually, pick up the lip a little bit

  • I’m going to starve if I have to feed myself with finding gold this way.

  • Finally, after I get the technique down, I find something!

  • Oh I think I see something.

  • Aarrrgh, there be lead in this here pan! Look at that!

  • We have found, in total, I think over 250 thousand pieces of lead shot.

  • Now you might not think of lead shot as treasure, but for a pirate, ammunition is critical.

  • And to an archaeologist, this stuff is like gold.

  • I spend hours sifting through the sand for micro-artifacts! And I have become pretty

  • good at panning for lead shot. But now it’s time for my next stop.

  • Let’s get out of here before she makes us do any more!

  • Not far from the field lab, tucked away in a warehouse is the Queen Anne’s Revenge

  • restoration lab. I meet up with the project director Wendy Welsh for a tour.

  • Hey Jonathan, welcome to the lab!

  • Hi Wendy, how are you?

  • Nice to have you.

  • Inside are tons of artifacts that have been rescued from the shipwreck, all awaiting restoration

  • so they can be put on display.

  • This is the North Carolina Department of Cultural Resources Queen Anne’s Revenge conservation

  • lab. What we do here is we take all the artifacts that come in here from the QAR shipwreck,

  • put them in storage. We conserver them and make them ready for public display and everything

  • in between.

  • Show me how you do that!

  • All right! Well, weve been out to the site and you have seen kind of what it looks like,

  • you have seen a site map and is the way these things come up are in large amorphous lumps

  • called concretions, and what we do here immediately is of course store them in wet storage.

  • All the artifacts are stored in tanks filled with water. They are being treated with special

  • chemicals and an electric current to drive the salt molecules out of the metal. Without

  • this process, these ancient artifacts would crumble into dust when they left the water.

  • Everything from the tiniest brass fitting to the largest iron cannon has to be slowly,

  • painstakingly treated with this process. And for large object like a cannon, the process

  • can take years.

  • So let me ask you, just out of curiosityif you took a cannon out of the water and you

  • didn’t do anythingyou were just likehey, check it out, we found a cannon

  • and you brought it out and maybe cleaned off all the marine growth and just put it in the

  • museum, what would happen?

  • Well, it would look pretty cool for like the first few days. And then after that it would

  • start to rust, and then the salts that had been permeating that iron for many many years

  • is going to start to crystalize as it dries out. And then one that happens it will start

  • popping off surfaces. And then you have no nice pretty cannon any more. That’s why

  • we have to do our process that we do and it does take a good while, but it’s actually

  • a payoff in the end if you think about it. Our cannon were underneath, submerged for

  • almost 300 years. To get into a conservation lab, for it to take five or six years to be

  • complete, that’s actually not a bad ratio.

  • Next Wendy shows me the largest artifact the team is restoring. It’s so big they had

  • to build a huge custom tank for it. We pull off the cover to reveal an anchor.

  • This is the anchor that we recovered from the site last May. It’s 12 feet long and

  • about eight feet, nine feet wide.

  • After seeing some of the artifacts being preserved, Wendy shows me how they get them out of the

  • concretions. It starts with an X-ray of the concretion, so the archaeologists can see

  • exactly what is inside them before they start doing any work.

  • This concretion has a couple grenades in it as well as a number of other items. The X-ray

  • clearly shows the location of the smaller artifacts buried within the concretion.

  • So this is an air scribe and I’ll turn it on and hopefully it won’t hurt your ears.

  • Next, using an air scribe, Wendy demonstrates how the marine growth is slowly cut away from

  • the artifacts, ever so carefully.

  • Using this technique, over time, thousands of artifacts have come out of concretions,

  • preserved and ready to go into an exhibit. In fact, right now there are more artifacts

  • than there is space to display them.

  • This is what’s to come as far as going into the museum next. So hopefully youll see

  • some of these on display soon enough.

  • I head over to the North Carolina Maritime Museum to check out the Queen Ann’s Revenge

  • exhibit, where some of the coolest finds are on display for the public to see.

  • There I meet up again with the Nautical Archaeologist David Moore to learn about the exhibit.

  • What were weeing here in just this small space is literally just the tip of the iceberg.

  • Weve got some 300 unique artifacts just in this one area. Of the material that has

  • been brought up, which is approximately half the site, we have only probably seen maybe

  • ten percent of that material. And of that ten percent, maybe five percent has been conserved.

  • You know, were looking at a fairly large volume of some very fascinating material that’s

  • going to be coming to light over the next decade to two decades, of work in the laboratory.

  • These amazing artifacts now on display have not only shed light on life of the world’s

  • most famous pirate, but also on the day-to-day happenings on a sailing ship in the 1700s.

  • And theyre here in a museum for all to see and enjoy.

  • Through the dedicated work of these archaeologists, underwater, on the water, and in the labs,

  • Blackbeard’s ship is being slowly excavated, conserved, studied and displayed for future

  • generations. Even though I have only seen a small part of the process, I have come to

  • understand and appreciate just how work and dedication this project has taken.

  • Arrrgh! Well, I spent me a day with the Queen Anne’s Revenge team. I came out looking

  • for treasure, but what I discovered isthe treasure is the ship!
