Brine Pool: An Underwater Lake
Earlier mapping surveys indicated a large crater the team nicknamed "The Pit of Despair" and suspected could be a brine pool. What is a brine pool? It's an underwater lake, with its own surface and shoreline. Water with such a high salinity from salts leaching out of the seafloor creates a barrier to the water around it, essentially a lake...underwater.
