Mission 8

We’re protecting dolphins from mass tourism


Dolphins are some of the most intelligent creatures on earth. They use complex sounds to communicate in ways we’re only beginning to understand, but noise pollution from tourist boats is destroying their acoustic habitat. An explosion of unregulated dolphin watching boats are forcing dolphins to yell underwater, making it hard for them to communicate and pushing them further away from the shore to areas less suitable to raise their young. For mission 8 we teamed up with AIMM Portugal, an organization studying and protecting dolphins in the region.

The Mission

In some parts of the Algarve coast, up to 150 boats head out to chase dolphins multiple times a day. All that noise and disruption is starting to impact the dolphin’s migratory patterns. To enact change, researchers need to know what’s happening underwater.

With the support of the Planet WIld community we were able to fund two hydrophones that can record underwater dolphin communication for acoustic analysis. This kind of evidence-based data is crucial to advocate for marine protection in Portugal.
