Abstract	The ocean regulates climate, supports biological diversity, supplies food and livelihoods, transports heat, stores carbon, and provides essential ecological and economic services. Effective ocean management requires observations that are spatially extensive, temporally continuous, scientifically reliable, and responsive to changing environmental conditions. Conventional monitoring based on research vessels, fixed stations, satellites, and manual sampling remains indispensable but is limited by cost, weather, access, observation frequency, and the physical risks associated with deep or hazardous marine environments. Autonomous underwater vehicles, ocean gliders, robotic surface vessels, sensor networks, and artificial intelligence offer a complementary approach in which mobile platforms can collect and process information closer to the observed environment. This paper examines the integration of underwater robotics, environmental sensors, artificial intelligence, adaptive mission planning, and multi-platform coordination in autonomous ocean monitoring. A structured conceptual review is combined with a transparent simulation of an illustrative mission-energy budget. The numerical values are not field measurements and are used only to examine system-level design priorities. The analysis identifies propulsion as the largest conceptual energy requirement, followed by scientific sensing, onboard artificial-intelligence processing, navigation and control, and communication. The distribution illustrates why endurance cannot be improved through battery expansion alone; hydrodynamic design, adaptive sampling, low-power sensors, efficient onboard inference, and energy-aware navigation must be optimized together. The study finds that onboard artificial intelligence can reduce communication demands by identifying, compressing, prioritizing, or summarizing scientifically relevant observations before transmission. However, autonomous classification introduces risks involving model bias, domain shift, missed events, uncertain navigation, sensor drift, cybersecurity, and limited explainability. Ocean robots must therefore retain raw or minimally processed information when feasible, communicate confidence levels, and support human scientific review. The paper concludes that autonomous monitoring should be developed as a distributed human–robot observing system rather than as a replacement for ships, satellites, laboratories, and marine scientists. Scientific value depends on calibration, traceability, interoperable data standards, ecological safeguards, robust recovery plans, and explicit reporting of uncertainty.
