Deep Hypersaline Anoxic Basins

Deep Hypersaline Anoxic Basins, or DHABs, are lakes of ultra-salty, no-oxygen water more than a mile below the surface of the ocean. They are some of the most extreme environments on Earth—and yet, life thrives there. DHABs are home to complex communities of microbes that have adapted to their hostile habitat and contribute to the global cycles of carbon, nitrogen, and other key elements.
