The Marine Global Earth Observatory (MarineGEO), directed by the Smithsonian’s Tennenbaum Marine Observatories Network (TMON), is a global network of partners focused on understanding how coastal marine ecosystems work—and how to keep them working.

We focus on biodiversity as the heart of healthy, productive ecosystems and coastal regions, where marine life and people are concentrated and interact most. MarineGEO marshals the Smithsonian’s leadership in discovery and convening power to advance frontiers in knowledge and provide it to policymakers to support innovative management and protection of our oceans.
