There are more historic artefacts on our ocean floor than there are in every museum in the world put together. Over thousands of years ships carrying every conceivable cargo have sunk in the rivers and oceans of the world. Protecting them is an enormous challenge. Thankfully there are heroes out there who are taking on that challenge. In this episode I was lucky enough to talk to maritime archeologist Jessica Berry, CEO of MAST (Maritime Archaeological Sea Trust) and her colleague Nick Wise. Nick is CEO of OceanMind. OceanMind is a not for profit which specialises in using the latest technology, unleashing the full potential of the latest AI from Microsoft. Together their two organisations have now set up the Maritime Observatory. This will protect underwater heritage from illegal looting - people going down, and ripping off bits of wrecks. So what Microsoft AI, and OceanMind's technology, allows MAST to keep an eye on ships behaving suspiciously on the surface in areas of important maritime wreck and heritage sites. All this means that wrecks can be looked after, war graves can be respected, in just the same way we should be looking after our vital fisheries and our maritime protected areas.
