Biographical Summary

Currently Dr. Long is the Deputy Lead, Sustainable Systems Science Focus Area at LBNL.

Dr. Long has served for the last several years both at PNNL and LBNL  as the Principal Investigator for the Integrated Field Research  Challenge Site (IFRC) at Rifle, Colorado. The IFRC Project was awarded  in September 2006 to a multidisciplinary team investigating the  relationship between protein expression and geochemical changes during  biostimulation for in situ treatment of uranium contamination. This  5-year field research project is part of the Department of Energy’s  Subsurface Biogeochemistry Program. Funding is $1.7M for 2007 and $3M  per year in 2008-2011. Dr. Long pioneered the use of IR imaging to  assess gas hydrate abundance in marine sediment cores, most recently  applying this technology during a gas hydrate drilling expedition in the  Indian Ocean on the Joint Oceanography Institutes Deep Earth Sampling  (JOIDES) “Resolution” drill ship sponsored by the Indian Government. Dr.  Long has been part of two earlier methane hydrate research expeditions  sponsored by the National Science Foundation, Leg 204 (offshore Oregon)  and Expedition 311 (off shore Vancouver Island). Dr. Long’s  participation in this work was  funded initially by the National Science  Foundation and subsequently by DOE’s Office of Fossil Energy.

Research Interests

Dr. Long has extensive research experience in geology and hydrology  ranging from studies of gas hydrates in marine sediments to fracture  characteristics, cooling histories, and the hydrology of flood basalts.  For the last several years, his research has focused on the  geohydrologic and geochemical controls on biostimulation of subsurface  microorganisms for in situ bioremediation of metals and radionuclides  and on the abundance, and texture of methane hydrate in marine sediments  using IR imaging cameras and other advanced technologies.
