FIU marine scientist Heather Bracken-Grissom. In creating a soundtrack suitable for the human viewing experience, we too are doing much the same thing as in nature itself, tuning into the noises that make the most sense of our world. Many deep-sea shrimp glow but researchers have found the light organs in deep-sea shrimp may have evolved depending on depth and habitat. Given sea creatures hear and use sound over a wide range of frequencies, from the infra-sound of blue whales, to the ultra-sound of pistol shrimp, all sea life only tunes into part of the spectrum of sound available. Some, like the wrasse tend to change from female to male whereas others, such as clownfish tend to change from male to. And because sound travels much faster in water than in air, there are potentially a much larger number sources of natural sound that could be heard at any given moment, so a final flourish of ‘artistic license’ is required to focus the viewer on the story. In fact, sex change is a very common reproductive strategy in many fish. And in mixing all the sound layers, the sound mixer must also create a 3D soundscape, for surround sound viewing. And crucially, a pleasant viewing experience for the audience. The challenge of the sound mixer’s craft is to be true to nature, whilst also creating an informative and entertaining film. Natural sound recordings, the sound effects, the narrator’s commentary and music must all be mixed to make the film’s final soundtrack. This helps convey the experience of ‘being there’ that is important for an immersive TV experience. In tracklay, other sounds are added: a woosh of a passing jellyfish, or the rocketing explosion of methane from the Deep Sea bed. S4E12 "Octonauts & the Bomber Worms" - deep-sea worms that grow bioluminescent "bombs" that they can eject to confuse predators: Osborn et al.You must enable JavaScript to play content (recently in the news again showing they're the same species as those extinct from Lord Howe Island - ) /8- Dr Jon Copley November 21, 2017 S4E8 "Octonauts & the Tree Lobsters" - discovery of "tree lobster" stick insects on Ball's Pyramid: Priddel et al. (I'm particularly fond of that one, as I was the first science journalist to cover the story in Dec 2004: ) /7- Dr Jon Copley November 21, 2017 S4E7 "Octonauts & the Loneliest Whale" - a whale with a song at a frequency unlike any others: Watkins et al. (a classic "trophic cascade" previously covered in my Masters marine ecology module!) /6- Dr Jon Copley November 21, 2017 S3E18 "Octonauts & the Urchin Invasion" - sea otters as a "keystone species", maintaining kelp forests by feeding on grazing urchins: Estes et al. S3E17 "Octonauts & the Immortal Jellyfish" - the astonishing jellyfish species that can transform from an adult back into earlier stages of its life cycle: Piraino et al. S1E19 "Octonauts & the Snapping Shrimp" - Dashi's slow-motion video reveals that the shrimp's snap comes from bubbles collapsing when it shuts its claw very fast - the same method used to investigate it by Verluis et al. S1E16 "Octonauts & the Enemy Anemones" - how groups of anemone clones go to "war" with each other: Ayre & Grosberg (2005) /3- Dr Jon Copley November 21, 2017 (& sightings of rare albino humpback whales such as Migaloo here - ) /2- Dr Jon Copley November 21, 2017 If it lives in the sea, its in this book. S1E14 "Octonauts & the Albino Humpback Whale" - natural sunscreen properties of mushroom coral mucus: Drollet et al. There is an abundance of beautiful images of creatures from shrimp to great whites, algae to sharks. So here are a few of my favourites with the links to the actual research papers that they're based on: If you want to feed the fascination of your little ones with the ocean, the Octonauts adventures are great - they firmly feature real science.
