The conversation unpacks why most coastlines experience two tides a day, why tidal behaviour varies so dramatically around the world, and what tide charts are actually measuring. Along the way, they examine spring and king tides, the influence of geography and ocean shape, and how tidal forces affect not just the oceans, but the Earth and Moon over deep time including the possibility that tides played a role in the origins of life.
