PRESSURISED: 037 - Deep digging with Andrew McCaig
Description
Our short and to the point PRESSURISED version of episode 37. If you don't have time for the full episode and want to get right to the science without any of our waffle, this is the place to be!

Alan is somewhere in the middle of the Pacific Ocean and Thom has been dissecting fish left right and centre at Te Papa. What better time to talk about deep-sea digging?
After the exciting news last month about the geological cruise that drilled through the Moho (the area where the Earth’s crust meets the mantle), we thought it would be interesting to talk with Andrew McCaig, the co-chief scientist for that expedition. Andrew talks us through the expedition's goals, achievements and the drilling process itself. Why were geologists interested in reaching this area and what exactly is serpentinisation?
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. And we want to thank our most recent patrons:
Tammy Frank | Martin Pollizotto | Ray M | Nicole Vite-Liebl | Anna P | Eric
Thanks again for tuning in, we’ll deep-see you next time!
Check out our podcast merch here! Which now includes Alan’s beloved apron and a much anticipated new design...
