What is a challenge?

A challenge in Ocean Hackathon® is either a simple idea or an idea that fulfils a need of the maritime community or a more mature project that needs a boost or special expertise. The owners of the challenge can be legal entities or individual people. 

To be taken into consideration, the challenge must:

• be linked with the ocean and seas, their sustainable development and/or their preservation
• lead to new ideas and/or innovative solutions
• be based on the use of data
• require the development of a prototype during the event

Check out the evaluation criteria to win your local edition and to participate to the Grand Finale in Brest.
