Scientists at the California Academy of Sciences have created a new device that can capture and transport deep-sea creatures to the ocean‘s surface without harming them, allowing scientists to better study the deep sea and potentially discover new species. The Submersible Chamber for Ascending Specimens, or SubCAS, works by first capturing wildlife within a small collecting jar. Once the SubCAS and its diver have ascended to approximately 200 feet below the surface, the jar is then moved into a larger chamber, which is sealed after an air bubble is also inserted. This air bubble expands as the pressure drops, which keeps the pressure within the jar at a constant level consistent with that experienced in the deep-sea creatures’ habitats.
