the shorter version


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!

I can see my house from here!

Specimens coming aboard

The Prof managed to have some downtime with the family in Antarctica and has some great stories to tell, he’s a chopper guy now. He’s over subs and only into helicopters now… the subs of the sky. 

 

Thomas Desvignes, Assistant Professor in the Department of Biology at the University of Alabama at Birmingham

We talk to Antarctic fishes expert Thomas Desvignes about the fishes that are only found there and their amazing adaptations. Blood without haemoglobin, antifreeze from junk DNA, all that good adaptation stuff! Be sure to check out Thomas’ comics in the links below.

Of course, we also had a remote coffee with Andrew, who has a shopping list of things he wants Thom to bring back.
