Deep-water corals with Di Tracey

The Deep-Sea Podcast

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 with her extensive work in making the marine sciences a better place for women to work. She talks us through what it was like to begin her career offshore, often being the only woman on board, and how she helped change the industry for the better.

In the news this week we have a few exciting new updates. We can indeed confirm that as of our last episode where we spoke about the vulnerability of subsea cables, there were multiple apparent attacks and cables were cut. We can only assume that hostile nations do indeed listen to the deep-sea podcast (thanks for subscribing!).

Andrew is back from his stint offshore and he is chock-full of stories for us. Brand new dragonfish species, near-misses with box jellyfish and also some cookie-cutter sharks. It's all happening!

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:
