The 12^th edition of Sea Tech Week^® will indeed take place from 12 to 16 October 2020, in what will be a unique format. Within the current health context, this international event, which every two years gathers together over a thousand participants – companies, research centres and laboratories, as well as students… - has reinvented itself in a virtual format embodying the theme “Marine observation: from seabed to space”. A local event involving protagonists from the Campus mondial de la mer community is due to be hosted in Brest in the run-up to the event.
