Plankton Trail

The plankton trail is the new tool of the participative objective plankton program.

océanopolis proposes a playful scientific walk to discover plankton in augmented reality. These "virtual fishermen" equipped with their smartphones and thanks to the mobile application "Street science" will be able to collect plankton and discover the richness of the roadstead of Brest.

To play, the walkers go on the mobile application and choose "objective plankton in the roadstead of Brest", they are then invited to scan 10 signs positioned from the statue "memory" to the beach of Moulin Blanc.

The planktonic organisms will reveal themselves to the eyes of the participants in augmented reality. Among all the species present is an intruder, can you guess which one ?


The summer season is just around the corner and the desire to take to the open sea and to fully enjoy one's passion is becoming more and more pronounced! Before rushing to embark, it is necessary to prepare your boat well, because even after wintering, it needs some verifications.

Here are 6 points to check before launching:

  • Hull inspection: a simple visual check is sufficient to detect any possible problems with the hull.
  • Mooring installation, ropes and fenders: it is important to check the condition of the anchor, the chain and the different shackles. Also, the mooring lines and fenders must not be damaged.
  • Check the bilge pump: test its proper activation
  • Check the various equipment: a short inspection of all the equipment present on the boat is necessary.
  • Make sure the safety equipment is working: it's all a question of checking the expiration date.
  • Test the electronics: just turn them on and check that they are working properly.

The whole technical team is there, on site to take the boats out of the water and install them on the careening area.

Passionate people at your service!
