Earthwatch propose des missions à travers le monde (majoritairement dans un environnement anglo-saxon) axées sur 4 principaux thèmes :

- vie sauvage et écosystèmes

- changement climatique

- santé des océans

- culture  et archéologie

Earthwatch engages people worldwide in scientific field research and education to promote the understanding and action necessary for a sustainable environment.

We work from several offices, located in the United States, United Kingdom, India, Hong Kong, Japan, Australia, and Brazil. We work with the general public, scientists, communities, educators, students, and corporate fellows. Our projects take place in more than forty countries around the globe.

Together with leading scientists, we create impactful field research experiences that facilitate and disseminate world-class scientific research. We measure our success through outcomes such as peer-reviewed publications produced by our researchers and our outreach events that engage wider audiences with our work.
