For the MACHC Region, this map will provide a valuable product and common resource that all will benefit from using. A complete bathymetric map of the MACHC Region will be a significant contribution to the Nippon Foundation GEBCO Seabed 2030 Project and will inform and improve regional marine spatial planning, disaster response, environmental management and scientific investigation activities, as identified in the Societal Goals of the UN Decade of Ocean Science for Sustainable Development 2020-2030. Completion of this map was also identified as a priority during the UN Decade of Ocean Science Regional Workshop for the Western Tropical Atlantic hosted by the Autonomous National University of Mexico (UNAM) and co-organized by the Government of Mexico with the Intergovernmental Oceanographic Commission (IOC) in April 2020.
