Wales, Lawrence Hall Of Science, Benach discussed on This Week in Science
Let me ask you a question. Okay. How do you track Wales? With my drone my drone. No. I don't track Wales. Oh, man. You go out on a boat with your Benach yours. Yeah. Are blow and then you try and follow their plumes. Yes. There is another way that you track whales, historically, which is by their poop. So there there's there's boats that all they do is go around and scoop up wail poop that floats fun fact, and then they can figure out who. And what kind of whale has been in the area so up until today? This was the main method of tracking whales was through well watching through occasionally some sonar stuff but overall occasionally poop. Not super effective. So they would researchers would try to follow these wail migrations try to estimate population size. Well, there's a new technology on the scene from max our technologies digital globe. Which is a system that uses high resolution satellite images to detect count and describe Wales when time maximum images, I think is max images. They sent me a picture of burning man. They do they do satellite imagery. Yeah. So I guess there. There are third party that does satellite imagery, and then you can kind of request images through them. So this is a new theory that using some of those images we can track Wales actually four different species. So this is. It's it makes sense Wales are big the thing about Wales. Okay. Wales are big. I'm backing it up. We all know whales are big. But until you see a whale in real life, or at least wail scaling skeleton scaling. Speak with the words. A real skeleton or real whale in person, or at least a scale model. You don't understand what big means? So I encouraged everybody to find the nearest museum natural history's Eum. Whatever it is that has some of these things on ground level because I know growing up as a kid I would go to the money bakeware him. They have Wales whale model. That's up above your head. You don't really understand? But when you you see it, actually, it was at the Lawrence hall of science is the one where I saw the whale skeleton on the ground in front, and I could really see the the sheer. It sounds stupid. But the sheer size of this enormous thing, you just don't get it. So what you see that you go? Okay. Yeah. Maybe you can see these things from space right there. So big. So this is looking specifically at southern right whales off Argentina humpback whales off a wife fin whales in the Mediterranean and grey whales off the coast of Mexico, and they've identified ten key pop. Already. They just started this. This is from we'll ecologist Hanoch coup bun. Yes. From the British Antarctic survey. I can't say normal words. How can I say that word at university in Cambridge? She says, quote, this is the most detailed imagery of whales captured by satellites to date. It's exciting that the improved resolution reveals characteristic features such as flippers and flukes which can be seen in the images for the first time. So if they can see specifics in flippers and flukes that means they can identify individual populations. Wow. So she says whales live in all oceans, many areas are difficult to access by boats or planes. The traditional means of.
