Since 1971, Earthwatch Expeditions has driven scientific discovery and conservation around the globe with a model that defines what hands-on field research can accomplish. Scientists lead the projects. Curious, committed people join them—collecting data, making observations and extending the reach, continuity and depth of each study. Together, they unlock insights at a scale beyond what any single small team could achieve on its own.

From oceans to forests, savannas to tundra, research supported by Earthwatch Expeditions has led to the discovery of new species, built critical long-term datasets, and shaped conservation strategies that protect wildlife and ecosystems. This work has helped create marine protected areas, support species recovery and advance global climate research, informing international policy and conservation at the highest levels.

At a time when environmental change is accelerating, the need for sustained, field-based science has never been greater. Earthwatch Expeditions turns participation into discovery and discovery into measurable impact.
