There's a Lake at the Bottom of the Ocean

A lake with a shoreline—but no sky above it. How can a lake exist at the bottom of the ocean? Explore the Gulf of Mexico’s brine pools: dense salty water, ancient buried salt, unusual shorelines, and the living communities found near some deep-sea seeps. Real expedition footage and original explanatory animations reveal the science behind a place that looks almost impossible.
