Underwater gliders equipped with novel optical and acoustic imaging sensors have a significant potential to collect and deliver ecosystem data, in particular in extreme environments like the Arctic ocean. Most of the technological building blocks to meet this challenge are available: extremely low power sensors, gliders and software for control and analyses, such as artificial intelligence (AI) algorithms, have been integrated and operated in coordination with other observing platforms, and open new perspectives for comprehensive observations in coastal and deep seas. BIOGLIDER addresses this scientific and technological challenge with an innovative and unique 'bio glider' integrated solution. Three smart devices, a vision profiler, a scientific echosounder and an acoustic modem will be integrated on commerciallyavailable gliders to provide a ‘smart’ service for zooplankton and fish ecology applications. It will be tested in Nordic seas and the Arctic ocean, meeting the needs of a wide range of customers, from research to the energy and fishery sectors.
