A couple of deep-sea scientists talk everything deep sea! Interesting facts, recent news, myth-busting and interviews with the most interesting people we know.

    Christmas Special 2 – We interview each other

    We like to let our hair down a little for the Christmas episode and do something a little different. Me and Alan crack out some mulled wine and decide to interview each other for this episode. Things get a little off the topic of deep sea but it’s all in good fun (if a little dark at times).

    018 – Sound in the deep ocean with David Barclay

    018 – Sound in the deep ocean with David Barclay

    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.

    017 – Going to sea with Larkin

    We love going to sea, it is probably the best part of the job. That’s where most of our adventures happen, that’s where most of the exciting discoveries and firsts happen and it’s where we meet some of the most interesting people. We want you to have a great time at sea too and not be put off by a bad first experience. We have put together some advice to help you out on your first trip.

    016 – Biodiscovery/Bioprospecting with Marcel Jaspars

    We are in desperate need for new bioactive compounds. Superbugs are on the rise as evolution finds a way of thwarting our antibiotics. 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?

    015 - Space pt2 - Design and management of extreme tech with Evan Hilgemann

    https://www.armatusoceanic.com/podcast/015-space-pt2


    We hunker down behind the blast doors and quickly record part 2 of our space episode before 426 manages to get through. That’ll make more sense once you hear the episode, or maybe it won’t! I may have gotten carried away on the sound design on this one.


    We are still exploring the parallels between space and deep-ocean exploration. 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 an incredible piece of tech grants us access to an exciting new frontier, it can be hard to manage all the different things we would like to do. Alan relays how, on his expeditions, data is first shared with the host nations and then access is requested.


    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! It turns out fleets of distributed intelligence rovers on the moon or a steam-punk rover on Venus aren’t all that farfetched. These are exciting times.

    014 - Space pt1 - The deep sea of other worlds with Kevin Hand and Casey Machado

    It turns out there is deep sea outside of earth in our solar system in the ice-covered moons of the gas giants. How likely are they to contain deep-sea life completely independent from the life that originated on earth?
