The importance of sharing your experience with photos on Sargassum monitoring:

First, the photos of sargassum seaweed will help you and the community to chose your best vacation destination !
Your photos are also so useful for the people dealing with this matter:

  • Because they allow us to identify which of the 60+ models in the sargassum family, are these sargassum.
  • It makes it clear where the affected areas are.
  • We can estimate the quantity of sargassum that has washed ashore.
  • We are able to calculate the direction and time it takes them to move.
  • It helps to define the recurrence of arrivals, etc…
  • It makes it easier to assess the damage caused to marine flora and fauna.
  • It shows the effectiveness of the resources deployed.

Whether there are few or a lot of algae, take photos/videos of the sargassum on the beach and share them on our social media.
