Hop aboard one of our Oceanic Society research expeditions!

Humpback Whale Monitoring and Research Expedition

Our 2019 expedition dates are:
February 16-25. (Group size is limited to 12 people max)


  • Learn alongside marine biologists as they conduct critical conservation research on the whales and dolphins in the region. See first-hand in the field how the use of drones assists in marine mammal research efforts.
  • Visit the mangrove-filled lagoon directly behind the village of Barra de Potosí, a nursery for hundreds of species of fish and birds including roseate spoonbills, boobies, white pelicans, herons, and egrets.
  • Spend one day exploring the nearby city of Zihuatanejo / Ixtapa and another visiting the Sierra highlands and a local sustainably-run coffee plantation.

Oceanic Society invites you to beautiful Barra de Potosí on Mexico’s Pacific coast to immerse yourself in this region’s rich marine and terrestrial biodiversity and to participate in the Whales of Guerrero Research Project.

As a participant on this expedition you will have the chance to help scientists better understand the important humpback whale population that inhabits the area during the winter months. For 3-4 days, visitors will work alongside American and Mexican scientists and local fishermen to spot, identify, and make scientific observations of humpback whales and any of four species of dolphins found in the area. We also frequently observe olive ridley sea turtles, manta rays, golden cow nosed and spotted eagle rays, red-billed tropic birds, frigate birds, and countless other noteworthy marine species. In addition to learning humpback whale fluke identification, the use of drones in field research, and hydro-acoustic recording techniques, you will also assist with recording other key ecosystem data. Our citizen scientists come away with a wealth of knowledge about humpback whale behavior and biology and the unique experience of being a part of a truly pioneering project.

We will also take time to explore the diverse surrounding ecosystems that include mangrove forests, salt flats, sea turtle nesting beaches, and sierra highlands, and we’ll explore quaint local towns, sustainable farms, and more.

Space is extremely limited and these expeditions fill up!
