We’ve been off-piste for a while now so we thought we’d jump straight back into the deep sea with a series of episodes on deep-sea habitats. We’re starting off strong with a huge episode on seamounts! We speak to a friend of the show, Ashley Rowden who’s an expert in all-things benthic and we find out why seamounts are just so cool. We also get a little distracted and reminisce about the ultimate offshore championship: sausage-fest.

We also get a little distracted and reminisce about the ultimate offshore championship: sausage-fest.
We get to hear from the scientists on board the RRS Discovery who are currently on an expedition to discover the life that exists on the seamounts surrounding St Helena and the Ascension Islands. A couple of our friends on board also recall their ‘crossing the line’ experience, and how they’re finding working on board a research vessel.
We have huge news! You’ll be very excited to hear that we have released a new design for our merch, featuring our favourite parasite - the tongue-eating isopod, Cymothoa exigua! A perfect gift this holiday season for the whole family.
Check out our podcast merch here! Which now includes Alan’s beloved apron and a much anticipated new design...
