"Protection of offshore activities within EEZ"
The SEAEXPLORER underwater glider is an autonomous sensing platform with very high endurance for both
coastal and offshore marine environments: the glider is driven by buoyancy changes (no propeller) for low
energy consumption and weeks to months of autonomous missions without the need for a surface vessel. The
SEAEXPLORER is an effective profiling tool for water column observation. Along the saw-tooth like navigation
profile the glider collects different physical and biochemical parameters through its attached sensors.
The French EEZ is the largest in world with 11Million Km² and on 24th September French Chief of Navy
Admiral Prazuck announced intention to deploy 200 underwater gliders for EEZ survey and protection (Cf.
news Mer et Marine).
