| Outline of Final Research Achievements |
Chemical oceanographic observation on ocean acidification and monitoring of atmospheric nitrogen deposition were conducted in coastal marine ecosystems of the Philippines at various spatial scales to clarify multiple influence of environmental alterations at the global (elevation of atmospheric CO2), regional (transboundary nitrogen pollution), and local (terrestrial freshwater loading, submerged groundwater discharge, and aquaculture activities) scales. In addition, to evaluate global and local environmental stresses on indigenous reef coral species, an outdoor manipulation experimental system was set up at Bolinao Marine Laboratory (northern Luzon) and carried out some model experiments to monitor ecophysiological and developmental responses of corals to ocean acidification.
