Transcript for Tracking Great White Sharks Off Cape Cod
Okay how mock quake planned plane can't you happen to the same time they can just hear him well I think people need to realize. Sharks in general and around 400 million years involving. Answer mine. If you think of all the animals including dinosaurs that have come and gone during that period. With sharks persisting. It's really quite remarkable and it's a testament to their ability as a line. It really well it. Gone too. Every happen. And the survivors you know they're absolutely survivors a unique. I'm good. In the ultimate goal really is to learn as much as we can about the he needs to be able to her tactic and support the conservation. Place check. Also here because we are on the heat and the way checks are swimming in areas that. People are recreating it's important for us to provide as much information as possible to use of public and to be its managers. The white shirt research we're doing is is centered in the Chatham Orleans area Cape Cod for one very simple reason. That's the one spot or spots were able to. Fine sharks and predictable numbers what we've been doing over the last seven years as using multiple technologies to get a sense of what these animals are doing in time and space. Out on the wired to need to heat and grab wired for about an hour each. So we get two major objectives and won its. Tank shirts to look at their movements in the others to get incensed when. We're conducting surveys we only have our spotter pilot with Catholics really. He define what is packed them as much as people would love to see them when their out opening. They're really hard to fines of the fighter pilot had been completely different view from the air. And he is able to mine start. And every shark that he sees easily give us a call on the radio and. That's chart it's south of us Christine there right now critical situation. We're gonna steam over there as quickly as we can. Once you get up to that shark John's drive in the boat I'll be out on the pole and I'll be waiting ethos that shark. He's right that. Like that each are that we come across doctor brakes on all first its video footage of the that shark can be identified by unique markings is really important to get a. What if it looks like. Because remarkably each and every way to show some very very. I call it video fingerprinting and. You know based on the color patterns from the scars and shapes of the fans we need to know who that he argued it is. We also tell whether it's a boy or girl and that's important. Check email after that if the shark is staying near the surface. He will look to tag a shack. We use a number different kinds of attacks and the ones we're deploying most frequently now or what we called acoustic. And the way we detect those taxes not to a satellite system but through experience acoustic receivers. So when the sharks' lives within a couple of hundred metres. Of one of these acoustic receivers receivers expect. He coasted to determine who then charges. And a dozen times. We'll go back to collect the game the receivers. All the data offer. We keep seeing the local movements sharks. We believe the force that is concentrating charts in that area is really the presence of large numbers of steals. The greats who population is that he if you populations of eastern seaboard. Has rebounded after. Decades of protection. And with that rebound comes its top predator in the top predators the white struck so you've got this you know this almost perfect storm that he will. Of factors you know you've gotten seals sharks and you. And so what we're doing with the legislature and service in their funding he is all about trying to figure out. What these white shirts do not only whether in mass. Where they go deep here and is that early various aspects of their natural history. Put it we put up. Patterns but the movement patterns has definitive generally colleges but we're also interested in the populations that it's what's the population size what direction it's going into. What are the real numbers of animals.
