At the bottom of the ocean, there are places where underwater “rivers” flow — complete with currents, banks, channels, and even waterfalls — but they’re not made of normal seawater. These strange formations occur when super-dense brine rich in salt or methane seeps out of the seafloor and settles into low-lying areas, creating a separate, heavier “liquid layer” that moves like a river inside the ocean. The most famous examples, such as the Black Sea undersea channel and brine pools in the Gulf o
