map the ocean floor at depths of six thousand meters. The vehicle is shaped to minimize water resistance during dives, and utilized acoustic communications systems to report the vehicles status while operating. Unmanned underwater vehicles are capable of recording conditions and terrain below sea ice, as the risk of sending an unmanned vehicle into unstable ice formations is much lower than that of a manned vessel. Glider type unmanned vehicles are often used to measure ocean temperatures and current strengths at various depths. Their simplicity and reduced operating costs allow more UUVs to be deployed with greater frequency, increasing the accuracy and detail of ocean weather reporting. Many UUVs designed with the purpose of collecting seafloor samples or images are of the towed type, being pulled by a ship's cable along either the seafloor or above. Towed vehicles may be selected for tasks which require large amounts of power and data transmission, such as sample testing and high definition imaging, as their tow cable serve as the method of communication between controller and craft. In 2021, scientists demonstrated a bioinspired self-powered soft robot for deep-sea operation that can withstand the pressure at the deepest part of the ocean at the Mariana Trench. The robot features artificial muscles and wings out of pliable materials and electronics distributed within its silicone body and could be used for exploration and environmental monitoring. Science Direct claims the use of Unmanned Underwater Vehicles has risen consistently since they were introduced in the 1960s, and find their most frequent use in scientific research and data collection. Oceanservice describes Remote Operated Vehicles (ROVs) and Autonomous underwater vehicle (AUVs) as two variations of UUVs, each able to accomplish the same tasks, provided the craft is properly designed. Ecosystem rehabilitation Companies like Duro AUS offer UUVs that can remotely collect and transmit water data for local governments. Duro helps the New York City government collect data around Randall's Island Park Alliance to monitor water quality and wetland health in the East and Harlem Rivers. Another project that Duro is undertaking is in conjunction with the Bronx River Alliance to help rejuvenate the river's wildlife. Using this data, state and local governments have made key decisions regarding the policies under the New York Ocean Action Plan for adjacent oceans, rivers, and estuaries. Concerns A major concern with unmanned underwater vehicles is communication. Communication between the pilot and unmanned vehicle is
