Bio

Dr. Dunne is head of GFDL's  Biogeochemistry, Ecosystems, and Climate Group.  He is an expert in ocean biogeochemistry, climate and earth system modeling with over 20 years of experience developing instruments, collecting field observations, and performing analysis and modeling studies.  He leads GFDL's ocean carbon modeling activities, and co-led GFDL's Earth System Model Development Team adapting GFDL's models for coupled carbon-climate studies and participating in the fifth Coupled Model Inter-comparison Project which received a Department of Commerce Silver Medal in 2013.  He has published over 70 peer-reviewed journal articles on topics relating to ocean ecosystem functioning and biogeochemistry, earth system modeling, climate change and its potential for marine biogeochemical and ecosystem impacts including ocean acidification.   He is well recognized in the community - as evidenced by his success in obtaining and managing grants - and contributed to the training of numerous undergraduates, graduates and post-docs.  In addition to his research activities, Dr. Dunne also serves on various international and national committees including the International MAREMIP steering committee, US CLIVAR ocean carbon uptake working group, OCB ocean time series advisory committee and as GFDL's science contact for NOAA's efforts in ecological prediction, ocean fertilization, marine microbes, and ocean acidification.

Research Interests

Dr. Dunne's spans a range of scientific research topics from the global (such as climate and earth system modeling and the effects of climate varaibility and change on marine ecosystems and biogeochemical cycles) to the local (such as biogeochemical processes and impacts of eutrophication on coastal ecosystems).  He combines chemical fingerprinting tools with mathematical models of physical and biogeochemical processes to elucidate controls on climate variability and change, biogeochemical cycling, and marine ecological functioning.  He also collaborate on a variety of projects assessing climate change impacts.

Ocean Biogeochemical Model development - For the last decade, he has been working to develop models of global ocean biogeochemical cycling to be incorporated into GFDL's global models for earth system reanalysis and projection.
