Visit Expedition 14

From November 28 to December 9, 2011, scientists explored super-salty, dense pools of water more than two miles deep in the Mediterranean Sea called brine lakes. What life forms live in this toxic, hyper-saline, lightless environment that lacks oxygen? From the research vessel Atlantis, researchers used the remotely operated vehicle Jason and a new deep-sea robotic micro-laboratory to study the chemistry of the brine lakes and the organisms that live there.

What are DHABs?

Deep Hypersaline Anoxic Basins, or DHABs, are some of the most extreme environments on Earth—and yet, life thrives there. DHABs are also very new to science.
