035 - Shipwrecks with Leighton Rolley and Lori Johnston

The Deep-Sea Podcast

To finish up our run of episodes on deep-sea habitats, we’re really excited to bring you this month’s episode on… shipwrecks! But we’re not going to talk about what you expect. We all know what shipwrecks are but do you know how to find them? We talk with Leighton Rolley, an expert in researching, discovering and documenting shipwrecks. And we don’t stop there. Our second guest, Lori Johnston is a microbiologist whose research has focused on the fascinating structures of rusticles: the rusty icicles that hang from shipwrecks like the Titanic.

We’re also very happy to hear from Don in this month’s episode with his tale of sailing on the infamous ghost ship, Glub Glub Orlova. Plus, we learn why Alan shares Darwin's opinion in hating Goose barnacles, or more accurately, one barnacle individually.

We’re really trying to make this project self-sustaining so we have started looking for ways to support the podcast. Here’s a link to our page on how to support us, from the free options to becoming a patron of the show. We want to say a huge thank you to those patrons who have already pledged to support us:
