ROVs - Remotely Operated Vehicles

Definition

Remotely Operated Vehicles (ROVs) are uncrewed, underwater robots that are controlled from a surface vessel, allowing for the exploration and monitoring of deep-sea environments. These vehicles are equipped with various tools and sensors that enable scientists to collect data, conduct surveys, and interact with the unique ecosystems found in places like hydrothermal vents. By using ROVs, researchers can access areas that are otherwise unreachable and gather valuable insights into the complex dynamics of deep-sea ecosystems.
