Today is a very special birthday. Our favorite and the most elusive colossal squid, Mesonychoteuthis hamiltoni, has been described for 100 years!

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. 

We’re talking hydrothermal vents and the specialised species that exist there.

We learn about life at the bottom of deep river ecosystems, and what parallels they share with the deep-sea.

We hear from the often overlooked figure in marine science, the ship’s captain.

We talk to Kat Bolstad about the deepest human milk, how she made a liar of David Attenborough and her experiences working in the field of deep-sea cephalopods.

The deep sea has more in common with cave ecosystems than you might think.

We discuss all things vision, the intricacies and oddities of vision in the deep sea.

While it may seem alien to us, bioluminescence is likely the most common form of communication on the planet.

The deep sea is not just the bottom! Most of the deep sea, in fact most of the habitat of this planet, is the huge 3D environment of open water

Are we able to keep deep-sea animals in the aquarium? We talk to the Monterey Bay Aquarium about their new Into the Deep exhibition which does just that.

One of the most exciting parts of our job is going to places that no one has ever been before and seeing things that no one has ever seen. It turns out, we were making that far harder than it needs to be, we can do all this from home!

It's very difficult to 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? We talk with Kakani Katija about ways of sharing data and automating its processing through Artificial Intelligence (AI).

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.

We call the ‘squid-phone’ – a special line used by scientists globally when they see something strange and squiddy. On the other end of that line is Mike Vecchione, the expert on cephalopods.
