Continental margins are the Earth's principal loci for producing hydrocarbon and metal resources, for earthquake, landslide, volcanic and climatic hazards, and for the greatest population density. Despite the societal and economic importance of margins, many of the mechanical, fluid, chemical and biological processes that shape them are poorly understood. The MARGINS Program, supported by the National Science Foundation, focused on the coordinated, interdisciplinary investigation of the continental margins through four initiatives: the Seismogenic Zone Experiment (SEIZE), the Subduction Factory (SubFac), Rupturing Continental Lithosphere (RCL), and Sediment Dynamics and Strata Formation: Source to Sink (S2S). Each initiative was associated with focus sites to address the complete range of field, experimental and theoretical studies, over the full range of spatial and temporal scales needed to address fundamental questions associated with each initiative. In 2010, the MARGINS Program was replaced by GeoPRISMS.
