A comprehensive system for detecting and mapping Submarine Groundwater Discharge (SGD) using AI, ML, and deep learning techniques. The system employs satellite imagery analysis, targeted sampling via drones, and detailed data collection with unmanned surface vehicles (USVs). The integration of advanced algorithms and multi-sensor suites ensures precise identification and mapping of SGD, enhancing the management of freshwater resources and minimizing environmental damage. Description: The present invention addresses the limitations of current SGD detection methods by providing a three-step solution that integrates satellite imagery analysis, drone sampling, and USV testing. The system utilizes AI, ML, and deep learning algorithms to process data at each stage, enabling accurate identification of potential SGD locations, confirmation of fresh water presence, and detailed mapping of fresh water sources. It comprises three main modules: a satellite imagery analysis module, a drone samplin
