The Sentinel Mission is a proof-of-concept challenge designed to revolutionize oceanographic research and promote scientific curiosity. Equipped with Teledyne Webb’s advanced glider technology, the Sentinel autonomous underwater vehicle (AUV) will set sail on the first ever circumnavigation journey by a robot under the sea. Our vision is to build global unity and contribute to scientific discoveries which fortify scientific knowledge, improve community resilience, and inspire a more sustainable relationship with our world’s oceans.
