Joel Johnson is a Professor in the Department of Earth Sciences at the University of New Hampshire. He teaches courses in Earth History, Structural Geology, Sedimentology, Geotectonics, Geological Oceanography, and research-focused classes. With a Ph.D. in Geological Oceanography from Oregon State University and an M.S. in Structural Geology & Tectonics from the University of Illinois at Urbana-Champaign, his research spans gas hydrate systems, sedimentology, and methane cycling in marine environments. Ph.D., Geological Oceanography, Oregon State University M.S., Structural Geology & Tectonics, University of Illinois at Urbana-Champaign B.S., Geology, University of Minnesota Duluth His work examines gas hydrate dynamics in settings like Hydrate Ridge (Cascadia margin) and Svyatogor Ridge (Fram Strait), focusing on crustal processes , fluid flow mechanisms , and authigenic carbonate formation . Studies in the Gulf of Mexico and Indian continental margins analyze hydrate accumulation controls, while Arctic lake research explores methane emission temperature sensitivity and microbial influences . Collaborative projects include 3D seismic analysis , tectonic stress modeling , and monsoon-driven sedimentation in the Bay of Bengal and Andaman Sea. Recent publications highlight earthquake-enhanced carbon cycling in deep sediments (2023), primary deposition controls on gas hydrate reservoirs (2022), and crustal-scale methane systems in Arctic regions (2022). His 15 most recent articles span 2023-2014, emphasizing gas hydrate systems , methane seepage , sedimentary diagenesis , and tectonic influences on fluid flow. Subfields include authigenic carbonate formation , 3D seismic imaging , isotopic geochemistry , and late Quaternary climate reconstructions . Contact: Joel.Johnson@unh.edu
