File:ROV Hercules Explores Below the Surface of Brine Pool Nautilus Live

Description
Brine pools are underwater lakes on the ocean floor formed by dense salty brine which refuses to mix with the seawater above. In this video, ROV Hercules takes a dip in one such pool, pushing hard with its thrusters against the especially high buoyancy of the pool to bring its cameras below the surface.

E/V Nautilus is exploring the ocean studying biology, geology, archeology, and more. Watch http://www.nautiluslive.org for live video from the ocean floor.
