MarineGEO research addresses how and why biodiversity is changing, how that influences ecosystem processes important to people, and how to use this knowledge to better inform management for resilient marine ecosystems. The research complements existing ocean observing programs but fills a critical void with its unique focus on biodiversity, seafloor (benthic) communities, nearshore areas where biodiversity and people are concentrated and interact most, and standardized methods that facilitate rigorous global comparative analysis. MarineGEO is also unique in its focus on collaborative partnerships and on coordinated experiments as a powerful means for identifying the causes and consequences of environmental and biodiversity change. MarineGEO focuses on sediment, marine vegetation, and reef (coral, rock, oyster) as the key habitats comparable across geographic regions. The MarineGEO core research plan consists of a set of standardized measurements of status, trends, and control of nearshore biodiversity, conducted regularly (generally annually) across partner sites, providing a powerful network for studying local and global change. SERC is home to MarineGEO's Chesapeake Bay study site. For more information contact site Principal Investigator Dr. Matthew Ogburn.
