So, for instance, we filmed Humboldt squid feeding at 800 meters off the coast Chile, and they don't like white light, so we had to film with infrared light. So if they weren't going to play ball with our lights, we'd have to rethink our strategy. But typically, you know, again, we don't want to just film portraits, we want to film behavior. "But, for instance, in the deep, we did have to use lights because we were 1,000 meters underwater, and sometimes fish would sort of stare a bit mesmerized. So it's with the rebreather we can sit in silence and observe week after week and gain the trust of this tuskfish, that we could open new filming opportunities. What's ingenious about that is that it's a demonstration that a fish can use a tool. So we can sit underwater - for instance, off the Great Barrier Reef in Australia - for 4 1/2 hours and wait in silence, for a tuskfish, which is a remarkable reef fish that has found a way to get at the soft meat in clams by smashing it against the side of a particular piece of coral reef. What's been amazing is with the advent of rebreathers, which are these underwater breathing that enables you to recycle your air so you don't exhale like with scuba, it does two things: It means you can dive in silence and you can dive for longer. "If the animal is impacted by your presence, you can't film natural behavior, and we're all about filming unique natural behaviors. On how the presence of humans changes animal behavior Scientists have recently discovered that many fish on the reef rely on sound at key stages in their life - and that man-made noise is interfering with this. We could never have done that 10 years ago, let alone five years ago, so it's huge advances in camera technology that open up new filming opportunities." Scientist Steve Simpson uses a multi-directional hydrophone to record the sounds of the coral reef. Now, that was only possible to film two years ago because camera sensor low-light technology was good enough to actually capture the light of these flashes. For instance, off the Sea of Cortez, mobula rays at night come in to feed on shoals of plankton, that, as they disturb them, light up in bioluminescence. "What new technology did was open up new opportunities. So there's just incredible information and new understanding of ocean life, of its complexities, its intricacy, and so it really was time to combine those three ingredients to make a brand-new 'Blue Planet' series." And 17 years on, we have huge advancements in camera technology, diving technology - but more than that it's an era of ocean exploration, the last decade.
#Blue planet ii season 2 episode 5 series
"That series was a seminal underwater series that captured the imagination of a generation of ocean-lovers. On making a follow-up to the first "Blue Planet" "I think, for many of us, the oceans are remote worlds, alien worlds - we even fear it - filled with slippery, cold creatures," says "Blue Planet II" series producer Mark Brownlow ( "And we tried really hard to show a different side of marine creatures and really reveal their true complexity and intelligence." Interview Highlights Seventeen years after the first "Blue Planet" series, the BBC returns with " Planet Earth: Blue Planet II," which uses cutting-edge technology to film in the oceans and capture the animals and creatures that live there. (BBC 2017) This article is more than 5 years old. During the filming of the surfing dolphin segment, the BBC team witnessed one of the largest swells to hit this coastline in the last five years. 'Scientists have named this strange place the Lost City, and many believe that it was at a place just like this that life on Earth first began, four billion years ago', writes the BBC.Giant waves breaking along the Wild Coast, South Africa. In one scene, spider crabs can be seen patrolling the deep seafloor, carrying pieces of coral or sponge in their hind legs, while another scene shows a hydro-thermal vent in the Atlantic producing complex hydrocarbons that are the building blocks of life. The creature also has pressure-sensitive canals in its head and along its body which help it to detect movement in the pitch-black world in which it lives.Īnother creature featured is the Venus' Flower Basket, a deep-sea sponge which harbours shrimp that take sanctuary in its protective walls when young but become imprisoned as they grow into adults. One of the oddest creatures featured is the fangtooth fish, which has the largest teeth relative to body size for any fish in the entire ocean. The episode will feature a range of weird and wonderful creatures.
