Organizations & Partners

Marine Global Earth Observatory (MarineGEO) is a growing global partnership between the Smithsonian and diverse collaborators. The Smithsonian Tennenbaum Marine Observatories Network (TMON) directs and coordinates the research efforts of the growing network of MarineGEO sites. TMON has a director, technical and support staff, and several advisory committees. 

The Smithsonian's existing marine stations serve as TMON’s initial core research sites:

Why Smithsonian

  • The Smithsonian conducts innovative, long-term research designed to understand change in both terrestrial and coastal communities.
  • We have active marine laboratories and field research facilities in coastal ecosystems.
  • We have a global reach of current research programs, partnerships, and relationships.
  • We are leaders in museum and data management and have the expertise to curate collections, data, and archives for long-term applications by current and future generations.

Program Overview

The ocean’s diverse marine life provides us with food, livelihoods, recreation, and inspiration. But our seas are changing rapidly, and we don’t fully understand the consequences.

MarineGEO is the first and only network of worldwide coastal observation and research sites to focus on understanding changes at the land-sea interface, where marine life is most abundant and human effects and demands on that life are highest. TMON directs and coordinates the research efforts of these sites and is also responsible for establishing new partner sites around the world.
