Dr. John Marra is the NOAA NESDIS NCEI Regional Climate Services Director for the Pacific Region.  He started working in this capacity in July 2010.  His primary office is located at the NOAA Inouye Regional Center (IRC) on Ford Island in Honolulu, HI. He is also an Adjunct Senior Fellow at the East-West Center, having served in this capacity since 2006. For nearly 30 years Dr. Marra has been working to connect science providers with science users, bridging the gap between data and information products to address issues related to natural hazards risk reduction and climate adaptation planning.  Dr. Marra worked for the NOAA Integrated Data and Environmental Applications (IDEA) Center in Honolulu, Hawaii starting in August 2006, where he spearheaded a project on extreme storms – strong winds, heavy rains, and high seas – in the Pacific. For the four years prior to that he worked at the NOAA Pacific Services Center providing technical assistance to Pacific Island jurisdictions and supporting the integration of multi-disciplinary research and observations to address issues associated with coastal natural hazards and community resilience. Before arriving to Hawaii and to joining NOAA in 2002, he worked independently for almost 10 years in Newport, Oregon as a consulting geologist for a broad range of private and public sector clients. Prior to that, he was the North Coast Field Representative for the State of Oregon’s Department of Land Conservation and Development.
