• Autonomous Underwater Vehicles (AUVs) navigate independently underwater carry out pre-programmed missions collect data using various sensors (chemical, biological, acoustic)
• Underwater Gliders use buoyancy-driven propulsion for energy-efficient long-duration missions (months at a time) gather data on ocean temperature, salinity, and currents
• High-Resolution Mapping Systems employ multibeam echo sounders, side-scan sonar, and LiDAR create detailed 3D maps of seafloor topography and habitat structures
• Remotely Operated Vehicles (ROVs) tethered to surface vessels allow real-time control and data transmission use manipulator arms for sampling and intervention in deep-sea environments
• Deep-sea Submersibles like human-occupied vehicles (HOVs) feature pressure-resistant hulls and advanced life support systems enable direct observation of deep-sea ecosystems (Alvin, Nautile)

Impact of technologies on ocean understanding

• Deep-sea exploration of abyssal plains and hadal zones reveals unique adaptations of life in extreme pressure environments (giant isopods, dumbo octopus)
• Under-ice investigations in polar regions and ice shelf cavities provide insights into climate change impacts and unique polar ecosystems
• Seamount and canyon surveys uncover complex topography and biodiversity hotspots critical for understanding marine ecosystem dynamics
