    Abstract: The glider has proven to be a fantastic asset for Passive Acoustic Monitoring (PAM) and Rapid Environmental Assessment (REA). With its long endurance, mobility and its navigation capabilities it allows easy data acquisition up to 1000m deep. The silent propulsion (no propellers) of the vehicle is especially suitable for PAM application.\nWe aim to present results from real world experiments at sea conducted in 2022/2023 from the point of view of the global system: it involves the glider itself (or a fleet of gliders), the communication with shore, the supervision system and a hybrid real time processing architecture (embedded at sea and deported on land). Two applications are presented: 1) The glider carries an acoustic array + a CTD, performs a pure REA mission contributing to rapidly assessing and analyzing the acoustic propagation context of an area of interest. 2) A fleet of gliders patrolling and monitoring marine mammal activities as part of the European life project PIAQUO. The latter is able to detect two species of marine mammals present in the Mediterranean Sea and to localize them using an array of hydrophones or time of arrivals on different vehicles. For both applications the presentation focuses on the complete system from the data collection at sea to the generation of processed and intelligible information such as mammals position or propagation modelling.\nDiscussion is extended to the next generation of smart gliders, enabling the users to integrate, by themselves, intelligence and adaptive behaviours onboard the platform through the integration of a user-friendly acoustic processor and backseat driver.
