Episode one in a two part series is 'Salty Love'. Nothing it seems stimulates reproductive urges like the ongoing threat of annihilation. Sea water is one vast womb, with the seeds of conception carried on every tide. Marine creatures have abandoned all constraints and spawn like there's no tomorrow. 'Salty Love' focuses on these under sea relationships. Episode two is 'The Living Graveyard'. Shipwrecks lace the floor of seabeds around the world. They lie in their watery tombs, but some are beacons of life donated by man to create an artificial reef at the bottom of the sea floor. 'The Living Graveyard' explores the wrecks of The President Coolidge (off the coast of Vanuatu) The Batavia (amongst the Abrohlos Islands), and The Yongala (off the east coast of Australia).
