Aquanaut – Episode 11: Brass, greed and the bends, as The Runnel Stone beckons the dive team back into its maw.

Discovering a gun in the forest of kelp, which turns out to be the wreck of the Moorview, from which we salvage brass that had been destined to make artillery shell casings in WW1. A strange experience of being covered in peculiar parasitic worms, and another close call, getting the bends after the lust for treasure gets the better of me.
