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.
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.
