The Thunder Bay Marine Sanctuary presents a series of short films, in addition to the featured film: All Too Clear . This 90 min film uses cutting-edge underwater drones to explore how quadrillions of tiny invasive mussels, known as quaggas, are re-engineering the ecosystem of the Great Lakes at a scale not seen since the glaciers. To capture this epic change, the husband-and-wife filmmaking team of Zach Melnick and Yvonne Drebert spent more than 150 days filming underwater, making it the most ambitious underwater film ever made about the Great Lakes. Part scientific exploration, part natural history adventure – the film showcases freshwater wildlife and environments like never before.
