The Deep-Sea Podcast

Our short and to the point PRESSURISED version of episode 46. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be! Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/046-rays   This month we're talking about the flattest of the elasmobranchs: the bottom-dwelling batoids - the deep sea rays and skates! We’re kicking off our cartilaginous fishes (Chondrichthyes) mini-series with the batoids - the rays and skates! Sharks are often associated with the deep sea, but did you know that batoids have been observed as deep as 3000m? We speak with Will White who researches elasmobranchs across the world and who has described 50 species! He talks us through the differences between sharks rays and skates, and how these species utilise the deep sea. We hear about their fascinating (and hugely varied) reproductive strategies like those that are viviparous (will keep the eggs in their uterus) and others that are oviparous (will lay the eggs).   We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

It wouldn’t be a Coffee with Andrew segment without a memorable insight into the world of a fish curator - and this month’s segment is no different! This time, Dr Thom asks Andrew about an unexpected factoid in one of Andrew’s publications: ‘Yolk smells and tastes like sweetened condensed milk’. We find out exactly how Andrew knows this.   We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

Our short and to the point PRESSURISED version of episode 21. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be! Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/021-ai   We have often talked about how difficult it is the get data from the deep sea… but would you believe that the bottleneck to our understanding of the deep ocean, at least as far as visual data, is processing those images? Turning a picture of the deep sea into a list of species, habitat type, sediment type etc. is a time-consuming process that requires a wide range of skilled people. Due to time/funding constrains a lot of valuable information is lost. A team looking at a specific question will have lots of information in their data that other teams could use. A picture is worth a thousand data points. We chat with Dr Kakani Katija, the co-founder of FathomNet, an open-source repository for labelled deep-sea imaging data. The platform is still in beta but it is hoped that it will allow scientists to easily and usefully share their amassed data in a single and easily searchable place. But what about that processing bottleneck? The tech-savvy listener may have noticed that a massive collection of labelled image data is exactly the sort of thing you need to train a Machine Learning or Deep Learning algorithm. Can we automate a lot of the time-consuming image processing and let the experts focus on the new and unusual stuff? It’s at this cutting edge that things get exciting and we may be at the cusp of a marine science renaissance.   We also launch our podcast merch! Please do send in any pics of you wearing the merch. We find the idea of real people in the actual world wearing this so surreal!   Feel free to get in touch with us with questions or you own tales from the high seas on: podcast@armatusoceanic.com   We are also on Twitter: @ArmatusO   Facebook: ArmatusOceanic   Instagram: @armatusoceanic   Read the show notes and find out more about us at: www.armatusoceanic.com   Glossary Artificial Intelligence (AI) – A science dedicated to making machines think in an intelligent way, mirroring a biological brain.

Dr Thom is back from his stint offshore, and The Professor pretty much now lives in a submarine, but that hasn’t stopped them from finally reuniting to make this special episode all about hagfish. We’ve talked about them a lot on the show, and decided it’s time to pass them the mic. So expect lots of slimy stories, toothy tales and a whole load of hagfish trivia you never knew you needed.   There’s lots of updates after so many recent deep sea expeditions, with Thom’s latest cruise discovering many new species and Alan sharing live updates from the sub. Keep up with their latest goings-on via twitter!   We speak to the king of the hagfish, Professor Doug Fudge, who has been studying these critters and their (in)famous slime for decades. We ask all the interesting questions like: how do they make so much slime, do they have any predators and why do they look like that?   We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast.

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/020-love   It’s February, the month of love and there’s love in the deep ocean too. We talk reproductive strategies in the deep sea with Professor Craig Young, Dr Autun Purser and Dr Mike Vecchione. How do you find a mate in the sparsely populated deep ocean? How can egg and sperm meet when you are fixed growing on a rock? How can your babies disperse and find a suitable habitat, especially if you live in a rare habitat like a hydrothermal vent?

With Dr Thom in the Bounty Trough and the Professor somewhere in the Pacific, this episode is quite the wild card. Whilst Thom has been busy crocheting fishing nets (that’s science folks), Alan was left to take the reins and he decided to go a little off-piste. We bring it back to the good old days with one of Alan’s (in)famous rants. This one is titled: When does the sea become the deep sea, and why it needs to be changed. Expect to hear about the history of why we decided what makes the deep-sea ‘deep’, and why it might not make sense anymore in our modern world. We’d love to hear your thoughts on this and whether you agree with Alan.    Finally, we check in with a key individual in the online deep-sea community space: Jeff Day. Jeff’s been on our radar for years with his immense knowledge of deep-sea cephalopods and we thought we’d finally hand him the mic. He talks to us all about his love of deep sea creatures and how he contributes to the field in unconventional ways.

Are you looking for a podcast episode that contains the return of the blobfish, golden crochet hooks and rare deep-sea squid? Well, look no further than this episode of The Deep-Sea Podcast!  It finally happened… we brought you an episode which was recorded almost completely offshore. With Dr Thom in the Bounty Trough and the Professor somewhere in the Pacific, this episode is quite the wild card.

Expect to hear about the history of why we decided what makes the deep-sea ‘deep’, and why it might not make sense anymore in our modern world. We’d love to hear your thoughts on this and whether you agree with Alan.  Dr Thom does make an appearance in this episode, giving us a run-down of how the research cruise is going (SPOILER: The blobfish is back). Plus, we hear about the original blobfish and how exactly it came to be an internet sensation, from the man who was there: new fan favourite, Andrew Stewart.

On the other end of that line is Mike Vecchione, the expert on cephalopods. We talk giant and colossal squid (to audible groans from Mike); the bigfin squid (Magnapinna), most famous for being the squid with the long trailing arms that’s often used as an example of terrifying deep-sea creatures, but also a species, genus and Family that Mike described and would love more sightings of.   We are also on: Twitter: @DeepSeaPod Facebook: @DeepSeaPodcast Instagram: @deepsea_podcast   Read the show notes and find out more about us at: www.armatusoceanic.com   Credits Theme – Hadal Zone Express by Märvel Edited by - Georgia Wells   #deepsea #marinebiologist #marinebiology #podcast #marianatrench #science #magnapinna #colossalsquid #giantsquid #gigantism #scicomm #deepseafish #deepseacreatures
