Buddemeier, R. W., P.L. Jokiel, K.M. Zimmerman, D.R. Lane, J. M. Carey, G.C. Bohling, J.A. Martinich. (in review) A modeling tool to evaluate regional coral reef responses to changes in climate and ocean chemistry.
Below: mild events in 2030, 2040, and 2080; a moderate event in 2050, and a severe event in 2070. (It looks bad, but with all of that it’s only down to 40% in 2070)
4. Future Plans
Global change and coral reefs (ocean acidification, coral bleaching)-Mesocosm Studies-Field Studies-Monitoring Network-Modeling
Ecological studies throughout the Hawaiian Archipelago(Integrated ecological studies of Main Hawaiian Islands and Northwest Hawaiian Islands).
Develop information needed for intelligent environmental management.
