File:ROV Hercules Explores Below the Surface of Brine Pool Nautilus Live-0

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.
