Abstract
The Marine Biodiversity Observation Network (MBON) is a global community of practice and network that links individuals and groups in an effort to monitor and understand changes in marine biodiversity. MBON functions within the larger framework of the Group on Earth Observations Biodiversity Observation Networks (GEO BON). These networks support mobilization of data to help nations to achieve the Sustainable Development Goals (SDGs) adopted by the United Nations (UN) in 2015 and to address their own internal, local management needs. Marine biodiversity data are important for allowing countries and local communities to monitor changes that result from local human pressures and climate change. Such data enable informed planning and management of coastal areas and resources.
