0:03 This is the NOAA Ocean podcast. 0:06 I'm your host, Alison Burrell. 0:08 Off the coast of North Carolina lies the remnants of the USS Monitor, now a protected national marine sanctuary. 0:15 From its sinking in 1862 until now, it has developed into a bustling artificial reef. 0:21 We are joined in the studio by maritime archeologist Tane Casserly from the Office 0:26 of National Marine Sanctuaries, whose specialties include 19th century warships and deep water archeology. 0:32 technology. In this episode, we discuss a new 3D imaging technology that's virtually bringing the USS Monitor 0:39 back to shore. 0:40 Now, let's dive in. 0:46 I'm here again with Tane Casterly, who works with the Office of National Marine Sanctuaries. 0:52 And today we're going to talk about the Monitor shipwreck again, 0:55 but the next new thing that's happening is this new imaging technology by Northrop Grumman. 1:00 And I'm so interested in this underwater imaging has the monitor been imaged before? 1:06 Yeah well that's a good question so the monitor you know over the years we have looked at it 1:11 with different types of sonar you know and sonar is a piece of equipment that really uses sound 1:15 to image things on the seafloor. 1:18 It's all different types of technologies but what makes working with North 1:22 at Grumman unique is the fine scale resolution that they're able to bring to what we're doing. 1:29 So I've been, you know, had the pleasure of working with our NOAA ships in the past and 1:33 they have multi-beam sonars that are hull mounted. 1:35 They do a great job, but those are designed to do a very particular thing, right? 1:41 They're imaging the sea floor. 1:42 You know, we can get some pretty good images of shipwrecks and things, but they have a very particular mission. 1:46 The mission of the North at Grumman equipment is really to look at much smaller, 1:51 compact sites where the NOAA mission is really with the ships, large scale, right? 1:56 They're looking at big swaths of the seafloor, as they should be. 2:00 This North at Grumman microsynthetic aperture sonar they have is just phenomenal. 2:06 So we were so lucky to partner with them, their technology for conservation team, to bring this to us. 2:12 And this is the first time that technology has been used outside of the defense or aerospace industries. 2:17 We're so excited to be unveiling it publicly for the first time. 2:22 It's just incredible what we can see with it. 2:24 So how does this new imaging technology work? 2:28 The sonar that Northrop Grumman brought out to the monitor is actually installed within an AUV, 2:35 an autonomous underwater vehicle. 2:37 This one happened to be one called a Remus 300, 2:40 you know, sort of a smaller AUV. 2:42 You know, you'd have four or five people actually to be able to recover it and put it in the water, deploy it. 2:47 So it's mounted within this AUV. 2:50 And what What makes AUVs so unique is that you program them on the surface and then literally let them go 2:57 on the side, and they go off by themselves without a tether, 3:00 without any of those kind of things that would encumber it, 3:05 and it goes off and does a survey and then pops back up and says, hey, I'm here, 3:09 I finished the survey, and you can download it. 3:11 So you can do much more targeted surveys with an AUV, it could be smaller in scale, 3:18 you don't have to have all the cables and all those kinds of things. 3:20 So we were just very lucky to be able to work with this technology. 3:24 So it's collecting information by itself, swimming around down there near the shipwreck. 3:31 But are you getting anything real time? 3:34 Not real time. 3:35 I think they could ping back and forth to it once it's on the surface. 3:38 I think it can tell us if it accomplished the mission or what it had to do and they can give it a new mission. 3:44 So it really is pretty phenomenal. 3:46 How long did it take from it entering the water to do the survey? 3:52 We tried to go out for multiple days, but we did run into weather. 3:55 So we got one really good day with it. 3:57 We might have put it down maybe four or five times perhaps. 4:01 And each time it went down was maybe for just over an hour. 4:06 It was really incredible. 4:08 And we have to remember too, the monitor site is quite small. 4:10 The ship as built was only 173 feet long. 4:13 So now it's a bit shorter, but it is a very small site. 4:18 But yeah, and that's what made it so perfect is that we could do this little targeted surveys 4:21 and get this phenomenal data. 4:24 So what's the difference between an AUV and an ROV? 4:28 Right, well, an autonomous underwater vehicle, an AUV, 4:32 and the difference between that and ROV, a remotely operated vehicle, is that the ROV has a tether. 4:38 So think of it almost like a dog on a leash, right? 4:41 So you're running out with your dog and it's got the leash on and the dog's running around a tree and then 4:46 you both get bought Right. 4:49 Well, it's kind of analogous to what happens with an ROV is that you have to be very careful with 4:53 that tether management And our wreck it can be challenging especially North Carolina with the currents that 4:59 that tether can get pulled under things pulled 5:01 in different directions It could wrap around delicate artifacts or structure on the wreck. 5:06 So if you can pick that out of the equation 5:11 So, you have something that's free swimming, 5:14 and you don't have to worry about the actual sensor itself and a tether, it's just that sensor. 5:20 It really simplifies things in some ways. 5:23 Other ways, it makes it more complicated. 5:24 But I believe it's a bit safer way to work in these delicate sites. 5:29 So that's why an ROV wouldn't work in the environment where the monitor lies because of the high tides? 5:35 The currents, we have these ROVs at monitor, 5:39 but really, I think I feel the most effective way that ROV works on a shipwreck is feeding you real-time video. 5:46 You can put other sensors on it too, but you get that real-time feedback. 5:50 But you can only actually move a certain distance from the ship. 5:55 So if you want to move to a different part of the shipwreck, 5:57 the entire ship has to move above it along with the tether, and that can be very complicated. 6:02 So it can give you great real-time interactions, but it also has limitations. 6:09 Once the AUV is deployed, how does it know where to go? 6:12 Is there a program? 6:13 Does it follow a grid pattern? 6:15 Yeah, so the engineers, they program the AUV, and traditionally, 6:21 as we would do a sonar survey on the surface, a grid pattern is done. 6:25 you call it mowing the lawn. 6:27 And that gives what you hope to be is 100 % or 120, 150 % coverage of what you're looking at on the seafloor. 6:34 And it basically goes up a little bit over and down, and then up and down, just like you're mowing the lawn, 6:41 and that covers an area. 6:43 So that gives you good data. 6:45 But what can be limiting with it is that it's really just a downward view at different angles. 6:51 But what's unique about the North of Grumman sensors and technology is that they do that as well 6:56 as circular surveys around the object at different levels. 7:01 So now you're getting those different perspectives of the object you're imaging on the seafloor so 7:05 you get even a better picture of resolution of that object and that's what makes them so unique. 7:13 Maybe we should start mowing our lawns in concentric circles. 7:18 Could be fun. 7:19 It could be fun. 7:21 So your crew had to sail out to this shipwreck to release this AUV and I know 7:26 we have video documenting this trip and it's shared on the Monitor website which we'll link 7:31 in our podcast episode page. 7:33 Did you anchor nearby to stay close to the shipwreck? 7:38 No, no, and so this is almost the same techniques we use as scuba diving out there. 7:42 Again, the currents are so strong there's no sense in anchoring because it could be difficult to recover. 7:48 The anchor, you know, you can move out of the way, but you also need to respond quickly. 7:53 So just like scuba diving out there, we would sort of free drift, free float, 7:58 and we would just hover in the area on the surface around the rack. 8:03 And really working in those kinds of conditions out there is probably the most effective way 8:06 and the safest way to do it. 8:08 But it is unique to the strong currents of North Carolina. 8:11 And then you also had a videographer that came out there with you. 8:15 We did. We did from NOAA. 8:17 So we were very pleased to have him out there and he shot, 8:20 you know aerial shots with the drone So we've got these beautiful shots of the AUV being deployed So, 8:26 you know can really demonstrate from start to finish What's it like to work with this types of equipment 8:31 and maybe we inspire Some young kids that they want to follow in our footsteps Was there any video taken 8:37 with the AUV or was it just sonar? 8:39 we did experiment by putting a GoPro small camera on the AUV, but We did experiment. 8:46 We didn't see anything other than some fish, but it's, um, but you know, again, let's try. 8:50 You never know what you might find by not just experimenting and theorizing. 8:55 Has this technology been used before? 8:58 So this is a proven technology at Northrop Grumman. 9:00 It's one of their newer technologies. 9:02 But again, it's really only used in that defense or aerospace realm. 9:07 So we were just so lucky that they brought it onto our project, which makes it a lot more public facing. 9:12 and I believe this is really the first time it's been used in this more public project 9:17 where everybody can benefit from it. 9:20 Do you suppose this new imaging technology will be used on more shipwrecks like saltwater and freshwater? 9:27 Yeah, I hope by basically using Monitor as a test bed, 9:30 and that's one of the wonderful things about Monitor where 9:32 it's always been pushing technology innovation from 1862 to today, 9:37 bringing all those new technologies to bear, 9:39 that people would look at the example of what achieved on monitor with Northrop Grumman using this technology 9:44 and how it can now be used and applied to other sites as well. 9:48 Whether that be shipwrecks, maybe it's sunken aircraft, 9:52 maybe they're sunken indigenous sites. 9:54 The technology and the resolution we can see for these things is mind-blowing and the fact that 10:00 we can collect that so quickly with the AUV -2 is very special. 10:05 What's exciting about this is its novelty and you're able to share the imagery with the public 10:11 so someone could visit the rec virtually. 10:14 So what kind of products are able to be produced with all of this data that the AUV is collecting? 10:21 Yeah, that's a great question about what we know. 10:23 What does this data mean that we're going out with Northrop and collecting? 10:26 Like what does it do? 10:28 What does it mean to me? 10:29 So for the sanctuary, it's wonderful because it gives us this hyper accurate view of the monitor. 10:35 So I can see structurally, is it changing? 10:38 Is it staying the same amount of time, what's happening? 10:40 You know, this is really the first time we've collected with that much accuracy and precision. 10:45 But for the public, you know, what a great way to interact with something in three dimensions. 10:50 So you see that and now you get a true sense of like, what's the monitor doing down there? 10:55 What does it look like? 10:56 What whole remains are there? 10:57 We're working with Northrop Grumman to identify those different features on the rec. 11:01 So you can see that in the sonar image and start understanding the rec site. 11:05 But what's also wonderful is that data has now been transformed into a three-dimensional model that 11:11 you can see and manipulate and spin around to get an idea. 11:15 And also, we're going to be getting a printed model of that too, the 3D print. 11:18 So it's just an extra layer of interpretation to say, hey, this is monitored today. 11:24 So that incredible prototype of the pre-battleship and all the technology to that. 11:31 Now we're using the latest technology to see what that rec looks like today. 11:35 What scale is the 3D printed model going to be at? 11:38 I wish it was life-size, but it's about two feet long, two, three feet long. 11:43 That'll still be really detailed. 11:46 Oh, yeah. The detail is phenomenal. 11:48 Again, what another great tool that we have to share this heritage? 11:51 I mean, we all are part of this heritage. 11:54 Part of the, you know, living in the United States, being citizens, we own this heritage. 11:58 So to be able to get it out there for folks to interact in different ways is what we should be doing. 12:03 So with the data that's being collected with the AUV, scientifically, what are you doing with that? 12:10 Well, so monitor, it is, you know, in some ways we image it, you know, with the photography of the video, 12:17 but you only get a certain like 2D sense of what the ref looks like. 12:21 So you could look at it on video and be like, okay, it looks pretty good. 12:23 But without having divers down there, 12:26 which we have done and still do, but it could just be really difficult to get a sense of how is that wreck 12:32 and the hull changing? 12:33 What are the variations? 12:35 You know, because if you're dropping measurements down to the seafloor, 12:38 but the seafloor depth keeps changing because of the currents moving sediments, 12:43 what do you use a baseline to document change? 12:46 How do you do that? 12:47 So by using this technology where now I can look at it in three dimensions and it is so hyper accurate 12:53 that now going back and doing future surveys, I can say, hey, the hull is doing great right now, 12:59 but maybe in 10 years time we've seen flexings and movements, 13:01 but because this this particular product created a baseline, I can track that. 13:07 But before that, we didn't have that data. 13:09 It was really just some of those visual data or the you know the very quick measurements we got with our dive teams. 13:15 Who went out on this ship with you to release the Northrop Grumman AUV? 13:28 What Yeah, well, I like to call them all expeditions. 13:31 This is an expedition. 13:33 Absolutely. So we went out with Northrop Grumman and their team on their research, Special Discovery. 13:38 Really it was the engineering team, the engineering and their field teams. 13:42 You know, they're the experts. 13:43 They're the ones who work with this equipment day in, day out. 13:45 I was there representing Noah and the archeologists, but we also had biologists out there. 13:50 So a group called Stantec, which is a partner with us with Northrop Grumman and they went out there as well. 13:55 and you know we experimented with what happens if we try to sample for eDNA material on a monitor. 14:02 So it's pretty innovative. 14:04 Environmental DNA. Yeah, so we look at it, you know, monitor is always going to be a test bed. 14:09 Let's experiment and try. 14:10 We're already doing this sort of revolutionary sonar. 14:13 If we experiment by attaching these sort of perforated balls that have a sponge-like substrate inside 14:21 that will collect the seawater, so we tried that. 14:24 I wouldn't say we found anything unique, 14:28 but the results showed us that it found species that are known to be up North Carolina. 14:36 I think that's just a great start and a way as a foundation to build upon that how sometimes 14:41 you can pair these different technologies to collect data. 14:44 It's the start, but Lord knows without some refinement what else it might be able to detect around different sites. 14:51 So recently you premiered the results of the AUV imaging with an event at the U .S.S. 14:58 Monitor Center. What are the next steps for the monitor? 15:02 Will there be more analysis of the imaging collected? 15:05 Will you go out? 15:06 Like you had said, oh, we were going to do two days and we only did one. 15:10 Are you going to go out and collect more data? 15:12 Well, for this particular project, it's at a close. 15:16 But the next part of the mission is let's get it out to the public. 15:20 right? Let's start in integrating this new imagery and technology into our educational programs. 15:27 Let's get it on the website. 15:29 We do, you know, several programs working with the local schools. 15:32 Well, now let's integrate this new technology into that. 15:35 So now we can start inspiring that next generation of marine scientists to come out. 15:40 So that's what I look at now is our mission is we have this wonderful data which cannot live just in a filing cabinet. 15:46 It's upon us now to get it out there and make it meaningful, and it really is incredible. 15:50 So that's the mission that I see next. 15:53 We're always open for new ideas at the Shipwreck site, but for this particular project, 15:58 let's get it out, let's make it meaningful, let's get it in school kids' hands. 16:02 There is a website associated with this expedition. 16:06 What are some of the most exciting things that's coming out of that website? 16:11 Yeah, well North at Grumman have built a web portal for us, 16:13 so you can click these buttons and you can explore what we did in 2025, 16:18 put the AUV in the survey and see all that incredible data and learn about it. 16:22 Maybe it inspires you to be an engineer or some other part of the technical aspects of surveys. 16:28 But the other part they built on that website was they looked back at Monitor in 1862, 16:34 which I'm particularly excited by. 16:37 So, the North at Grumman has so much capability, all these different facets of things they can do. 16:42 So one of them was building 3D models. 16:45 So I asked them, monitors deck layout changed three times in 1862 as they learned more into improvements. 16:52 Can you build us three different models to demonstrate that? 16:55 And they said, yeah, we can absolutely do that. 16:57 So one of the things on the website people are going to see now are these three separate 17:02 and unique monitor 3D models. 17:05 They can manipulate, move, and learn how monitor changed over time, which is incredible. 17:10 We've never had that before. 17:11 And the other exciting part is, you know, 17:15 when we talk about the ship sinking and what that was like, 17:18 what that went through the storm and the incredible heroism of the men that were saved by the sailors 17:24 of the Rhode Island, that incredible night, they also created an animation of that sinking event for us. 17:31 So we can work with the conservation team here at the Mirrens Museum and Park, 17:37 and look at what the artifacts told us about some of the damage and things we saw, these recovered items, 17:43 like part of the monitor scale, the prop, you know, the damage that we see at the stern of the shipwreck. 17:49 So how we believe the vessel sank by coming down by the stern, turning slightly to starboard, 17:57 crashing into the sea floor, but crushes the stern of the vessel, which is the end of the vessel, 18:02 and the right-hand side, it crushes that, and then everything flips upside down and lands on top. 18:08 And I believe we've recaptured that in this animation how Noah thinks the vessel actually went down 18:14 that night, December 31st of 1862. 18:18 So you've collected all of these artifacts from the monitor and brought them up. 18:24 How do you conserve them and make sure that they don't just disintegrate when they come up to the surface? 18:31 Yeah, well, it's a great question. 18:32 You know, people often think that, you know, you go out to a shipwreck or another site. 18:37 You've recovered something and you bring it back to the surface and everybody's celebrating 18:40 and that's the end of the story. 18:42 So that is not the end of the story, right? 18:45 So before we do anything like that with the Thompson National Marine Sanctuaries, 18:50 anybody's really responsible archaeologists that, okay, that's one part of the story, 18:55 but now it's you're going to need to have funding in place to pay for this thing. 18:58 Where's it going to go? 18:59 Who's going to conserve it? 19:01 This is its own expertise and discipline, right? 19:05 You need to have the right people doing this. 19:07 So, we are so lucky to have partnered with the Marin's Museum and Park here in Newport News, Virginia. 19:13 So, their conservation team is incredible 19:15 dealing with all of this government-owned archaeological assemblage, right? 19:21 So, it's that the science that goes into it is incredible, 19:25 but what I find most exciting by watching these experts here is that they're not only saving our heritage, 19:32 right, for all of us, but they're pioneering brand new techniques, 19:36 because as I mentioned, something that the scale has never been done for. 19:40 So it's known how to conserve metals and things, but to this scale, it's never been done. 19:45 So they're pioneering new ways and influencing the entire field of marine metal conservation for the better, 19:53 all because of monitor. 19:55 How to do it safer, how to do it cheaper, 19:58 you know, what can we do to accelerate the process, 20:01 but still ensure the safety of artifacts, these incredible one-of-a-kind pieces. 20:05 It is incredible what they've achieved here, and again, it's all due to the monitor. 20:10 And is there a virtual way to visit the wreck? 20:14 Absolutely. So the final part that Northrop Grumman built for us was what we call the Wreck-to-Reef model. 20:21 So this is the story we've been telling since the end of the large artifact recovery. 20:26 So from 2003 till today, we're looking at the wreck historically, 20:30 archaeologically, fed as a thriving reef as well, which is important. 20:35 So we work with the Northrop Grumman team and we said we would love to see a model of the shipwreck 20:40 on the sea floor, but let's put that marine life on it. 20:43 The marine life, the species we know that we've documented on that site, can we put it on there? 20:48 And they did. 20:49 So we've got this gorgeous 3D model interaction 20:52 of the wreck on the sea floor that you can zoom in on and spin around and you'll see lionfish, the invasive lionfish. 21:00 you'll see sand tiger sharks, you'll see Atlantic spade fish, you'll see so much more. 21:05 So what an incredible way to also now add in that sort of marine biology ecological component, 21:10 which is so much of what monitor is today for the public. 21:14 I love that the monitor is still making history. 21:19 Yeah, it really is. 21:20 You know, it sounds like, you know, we're all excited about saying it, but it absolutely is true. 21:25 I mean, is the way it influences things and we'd look at, 21:28 You know, what what does the monitor mean to us as a people? 21:31 Why don't it inspire people those same same things that inspired people, 21:35 you know, a hundred plus years ago 163 years ago the same aesthetics of this little ship that rallied us as a nation. 21:42 I Think it's still there today. 21:44 You know, we have a lot we can learn from that Well, 21:47 we've got so many firsts right at the first ironclad the first National Moon sanctuary the first public 21:53 facing Northrop Grumman AUV imagery and And who knows what the next first will be for this ship. 22:01 Yeah, exactly. That's what Monitor is known for. 22:03 And we're open to that. 22:04 Monitor is a testbed, and we're open to talking to new partners, you need to do new things and bring in new technologies. 22:12 And I'm also looking forward to seeing the future of this AUV technology 22:16 and how it can help protect our coasts, our oceans and our coasts. 22:21 Yeah, exactly. You know, it can be so difficult to document and research and visit these deeper areas of the ocean. 22:27 So technologies like this are bringing it to light. 22:30 I can't wait to see what happens in the next five or 10 years. 22:33 Well, I am looking forward to hearing more from your investigation of the Monitor 22:37 and unearthing interesting historical facts. 22:41 This has been an absolutely fabulous conversation. 22:44 Thank you so much, Tawny. 22:46 Oh, I'm so happy to be here. 22:48 And I'm so proud to be able to talk about Monitor and all the ways it's affected us from 1862 to 2026. 22:55 I mean, it really is an incredible story, and I hope the story keeps inspiring all of us, 23:00 you know, as we move forward. 23:04 This has been Alison Burrell with the NOAA Ocean Podcast. 23:08 Thanks to our deep-water archaeology expert Tane Casserly, 23:12 whose stories and work on the USS Monitor have brought it back to life. 23:17 Explore the new 3D images of this shipwreck through the National Marine Sanctuary website linked 23:22 on the podcast page. 23:24 Be sure to check out all our episodes through the National Ocean Service website or wherever you get your podcasts. 23:30 Thanks for listening. 23:32 Let's keep making waves.

دربارهی این قسمت In this follow-up episode, we travel back to the USS Monitor, resting in the depths of the Atlantic Ocean within Monitor National Marine Sanctuary, to discuss a new, innovative underwater 3D mapping technology. The USS Monitor sank in 1862 during the Civil War — a tumultuous time in American history — with battles fought both on land and sea. Using this new mapping technology, 3D maps of the USS Monitor shipwreck will allow the public to take virtual trips to the bottom of the ocean to explore the nation’s first national marine sanctuary. Dive in to discover how this cutting-edge imaging technology captured this historic ship and how the images will be used to inspire future explorers.
