“Exploration is about the place, adventurism is about the person, science is about the question”

Professor Alan Jamieson

 

In an episode recorded earlier than usual, which is to say not recorded late, and so perhaps recorded right on time?... we are talking about environmental DNA or eDNA. 

Thom is headed off to Norfolk Island, north of New Zealand, to characterize t...

We are still talking about Antarctica, the continent that keeps on giving!

Alan and Thom discuss trying to stop working momentarily, constructing a treehouse, and acquiring a shark.

In the news, we rattle off a list of newly discovered species with some very cool (but hard to pronounce) names. There has been a lot of squiddy news. Footage of divers swimming with a giant squid has resurfaced; in an exclusive for the podcast, Alan ha...

It’s the last in our run of episodes about Antarctica. We are all back home, and we promise to stop bothering the poor continent.

 

Thom couldn’t talk about it until after the press release, but the Schmidt Ocean Institute cruise he was on had to look at the seabed under a 150-meter-thick ice shelf right as it moved out of the way. We talked to the science leads on that cruise, Patricia Esquete and Sasha Montelli. We learned about ...

Alan and Thom discuss returning to an inbox of horrors and readjusting to time away.

More cable cutting in our news updates, blobfish being voted fish of the year, and the tongue-eating louse potentially being invertebrate of the year. We don’t want to say we influence the news, but it seems a little spo...

Coming to you from an Airbnb, above a ski hire shop, next to a construction site in Ushuia, Argentina… It’s a very special episode as we continue to pester Antarctica.

We are here for today is a very special birthday. Our favorite and most elusive colossal squid, Mesonychoteuthis hamiltoni, has been described for 100 years but never seen in its natural environment! We are having a birthday bash for the big girl.

The gang has swapped places, Alan is back in Perth and now it’s Thom’s turn to hit Antarctica. He’s out with the Schmidt Ocean Institute on the Antarctic Climate Connections expedition to the Bellinghousen Sea, to the west of the Antarctic Peninsula. 

He will record, edit and upload a podcast from there… somehow. This episode may sound a little rougher as a result, but the content is gold as ever… Underrated belter alert.

It’s a big one! With The Professor down in Antarctica and Dr Thom not too far behind him, we’ve got an update live from the field. We’re talking about Antarctic submarine dives, below-freezing trenches, unexpected uses of glacial ice and, of course, the importance of growing a beard…

With Dr Thom and The Professor busy prepping for their upcoming expeditions offshore, we had time to squeeze out one more episode before they set sail.

We caught up with the legendary Di Tracey from NIWA to talk all things deep-water corals. How they live, what makes them different from their shallow water relatives, and how they are adapted to life in the deep dark ocean. Di's long career in deep-sea ecology is also intertwined w...

With the professor momentarily pinned down in Perth, we thought it would be the ideal moment for him to talk to us all about his local waters, the great Australian deep sea.

Did you know that 70% of Australian waters are deeper than 1000m? Now that’s a lot of deep sea! We hear from the Minderoo-UWA Deep Sea Research Centre’s deputy director, Dr Todd Bond about the huge array of marine geographical features and biodiversity in Austr...

We made it to episode 50 and managed to pin down the professor to tell us all about his adventures offshore in the world’s second deepest point: the Tonga trench.

Expect to hear all about how the colossal deep-sea expedition is going, including the time Alan piloted a submarine to 2000m, stumbled upon a rarely seen deep-sea squid, and made poor Steve’s life difficult (the onboard media guy). Life on land is also just as...

As it turns out, returning to life on land after a mega deep-sea expedition takes a lot of work! So, whilst we aren't quite ready to share with you our Tonga Trench special, here is a mini-episode to keep you busy until we get back to you with episode 50.

We're talking all about SQUIDTEMBER with long-time friend of the show, Kat Bolstad from the AUT Squid Squad. Which squid will reign supreme come the end of the month? It's up to y...
