The Smithsonian Institution Marine Global Earth Observatories, or MarineGEO, is the first truly global-scale network of ecological observatories dedicated to understanding changes in the structure and function of marine ecosystems. This network is unique in its commitment to standardized, long-term measurements and innovative experiments across traditional disciplinary boundaries, occurring at unprecedented spatial and temporal scales. It is only this approach that can lead to fundamental understanding and sustainability of our oceans.

MarineGEO will provide a critical framework that combines the strengths of the Smithsonian with those of other partner organizations and institutions throughout the world to:

1. transform our understanding of biological/ecological processes in marine ecosystems, including forces of change and their consequences.
2. provide the science needed to improve ocean health (e.g. resilience and sustainability).

Our vision of MarineGEO is a global-scale network of sites which spans latitudes and ocean basins and engages a diverse consortium of partner institutions and collaborators. This network provides the platform for integrative, multi-disciplinary research to answer a diverse range of fundamental questions about marine ecosystems, their function, and sustainability.  MarineGEO will also provide a vibrant and dynamic platform for education and outreach activities for students, citizen-scientists, resource managers, and policy-makers.
