Whales, Dolphins & Whale Sharks of Baja

Earthwatch Expeditions builds on the legacies of Earthwatch and Natural Habitat Adventures, where travel centers on purpose, contribution and connection. Watch our new video for a preview of the hands-on research, experiences and wildlife encounters that await.

What can Baja’s marine giants reveal about a changing ocean? Lenin Oviedo, Ph.D., Lead Scientist for our Whales, Dolphins & Whale Sharks of Baja adventure, takes you into the waters of Baja California Sur, where Earthwatch Expeditions travelers work alongside researchers studying marine wildlife. Discover how you'll photograph animals for identification and use hydrophones to listen beneath the surface while exploring the Sea of Cortez and Pacific coast. Plus, learn how hands-on research helps scientists understand the impacts of warming seas and growing tourism.

Sharks have ruled the oceans for more than 400 million years. But today, many species are declining due to overfishing, bycatch and the loss of critical marine habitats. In honor of Shark Awareness Day, marine biologist and Expedition Leader Eric Ramirez explores the surprising role these apex predators play in keeping entire marine ecosystems healthy. Discover the science behind shark behavior, separate myth from reality, and learn why protecting sharks is essential to the future of coral reefs, healthy fisheries and resilient oceans.

In 1971, Earthwatch set out to place everyday citizens alongside scientists in the field—a model that inspired Ben Bressler and helped shape Natural Habitat Adventures. Today, that legacy continues with Earthwatch Expeditions by Nat Hab, blending hands-on research with conservation travel. Join Ben Bressler and Earthwatch Expeditions’ Managing Director Renata Haas and Director of Research Stan Rullman to learn how you can work with scientists and contribute to conservation research in places like the Amazon, the Arctic, Africa and beyond.
