The Atlantis Research Submersible Explorer is designed to complement scientific research conducted at the Atlantis 1 underwater research facility. With a range of more than five miles and a depth range of 200 m, the vehicle is ideal for exploration in and around the Blue Hole. The standard operating time of twelve hours allows up to two researchers to engage in extended scientific studies.
