Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/019-squid   As promised in the Christmas special, we call the ‘squid-phone’ – a special line used by scientists globally when they seem something strange and squiddy. 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

From being repeatedly thrown off your bed in a storm, to seeing blue whales out of your porthole, working at sea doesn’t leave you short of stories. And with Dr Thom and the Professor both heading offshore soon, they thought what better time to share some of their sea stories. From tips on how to hold your pee for 12+ hours, to tales of typhoons, this episode is jam-packed with real-life tales from decades of working offshore.

We think of the deep sea as an eerily quiet and spooky place but that isn’t completely true, animal communication, seismic activity, human noise and even the sound of rain and waves from 10 km above. We chat with undersea audio expert Dr David Barclay about the fascinating audio properties of the deep ocean.

In our third episode of The Deco-Stop we begin to tackle the immense topic of eco-anxiety.

Over the last 3 years, it’s been a privilege to have Don recount his endless stories with us. In some attempt to raise a toast to him and all that he’s done for the community, we bring you this Don Special episode.

Read the show notes and find the full episode here: https://www.armatusoceanic.com/podcast/016-biodiscovery   We are in desperate need for new bioactive compounds. Super bugs are on the rise as evolution finds a way of thwarting our antibiotics. We are also continually on the hunt for compounds that can fight disease, ease suffering or get your teeth super white. The natural world has been experimenting for millions of years and has come up with solutions far more elegant than we could come up with. The ocean, and in particular the deep ocean, may be the best place to look for new compounds but is this a threat to the ocean? It is often mentioned alongside seabed trawling, climate change and mining as a threat to the deep ocean. Should we call it bioprospecting or biodiscovery and what’s the difference? If most of the world’s ocean belongs to everyone, who owns a discovery? How do we ensure that developed nations, who are better equipped to benefit from a discovery, don’t leave developing nations out? Are companies really patenting naturally occurring compounds? If we find something exciting, what is the process for it becoming the next wonder drug? While they both agree that looking for new compounds in the deep sea sounds good, Alan and Thom are soon stumped by the complexities of actually making that happen in a fair and sustainable way. Luckily, they can call on Professor Marcel Jaspars, head of the Marine Biodiscovery Centre to help us through the practicalities of biodiscovery but also its political and ethical complexities.

Mantle – The muscular tube that makes up a squids body. Mesopelagic – Open water fish between about 200 and 1,000 metres (approximately 650 and 3,300 ft) down. SoFAR channel - sound fixing and ranging channel. The SOFAR channel acts as a waveguide for sound, and low frequency sound waves within the channel may travel thousands of miles before dissipating. Vertical migration – Every night, mesopelagic fish come shallower to feed. This is the largest migration on Earth and it happens every day. Credits Theme – Hadal Zone Express by Märvel  

A shorter, to-the-point version of The Deep-Sea Podcast episode41 - Deep diving whales with Nicola Quick

Air-breathers in the deep-sea? That’s right! Dr Nicola Quick talks us through the deepest diving whales, the elusive beaked whales.

It feels like technology and access is really accelerating in both spheres. Don calls in to teach us about the amount of water in our solar system and the potential new job title – Planetary Oceanographer.   When samples or access to a vehicle is limited, how can we ensure that resources are shared fairly? We have seen it lead to disagreements on ships. With something as singular and precious as a Mars rover, how are its objectives planned? Evan Hilgemann, mechanical engineer and Curiosity Rover driver with NASA’s Jet Propulsion Lab (JLP) joins us to share how a rover is managed. We chat about the parallels between exploring mars and exploring the deep sea, the similar issues we face, what we can learn from each other and most excitingly, where is technology heading on both fronts! These are exciting times.   Feel free to get in touch 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 Autonomous - Something which can get on with things without human control AUV - Autonomous Underwater Vehicle Distributed intelligence – a very fuzzy term but basically multiple ‘stupid’ elements working together to do complex processing or make complex decisions.

We hear about yet another deep sea habitat - the submarine canyons! How are they formed? How do they influence their surrounding habitats and what sort of critters live there?
