040 - Submarine canyons with Teresa Amaro

The Deep-Sea Podcast

So everyone has been pretty busy but we finally got round to finishing off our deep sea habitats series with this episode on submarine canyons. We talk with Dr Teresa Amaro, from the University of Aveiro in Portugal about these hugely important habitats in the deep sea and how they influence the fauna of the continental shelf. Plus, we get to hear the infamous story of when The Professor and Teresa docked in Lisbon during a cruise and Teresa was able to clear out a bar for the whole of the crew.

Plus, the deep sea has been all over the news this month with lots of new papers being released. Magnetic bacteria have been found by the (phenomenally named) HYPER-DOLHPIN ROV, mysterious markings on the seafloor turn out to be face-planting fish, and scientists have been training jellyfish to navigate through assault courses (kinda).

The Professor’s deep sea research lab have also been busy recently with lots of exciting videos coming out from their landers. Plus, one mystery creature has the whole team stumped. Is it a nudibranch? Or is it something else entirely?

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:

GLOSSARY

Canyon - Narrow steep-sided valleys that cut into continental slopes and continental rises of the oceans.

Holothurian - A sea cucumber. They feed by ingesting sediment to obtain the nutrients.

Lander - A piece of deep sea equipment which free-falls to the seafloor and collects data via cameras, collection equipment etc.

ROV - Remotely operated vehicle. These are robots, tethered to the surface vessel which are used to explore an area in the deep sea, whilst being operated from the surface.
