SubCAS: A Portable, Submersible Hyperbaric Chamber to Collect Living Mesophotic Fishes

Accompanying the recent technological innovations in remotely operated vehicles, submersibles, technical SCUBA, and closed-circuit rebreather diving gear, new discoveries are being made on mesophotic coral ecosystems around the world. However, collecting live fishes from mesophotic depths (60-150m) is challenging, given the difficulty of accessing the habitat, catching the fishes, and the barotrauma that can result from rapid decompression...
