Jeffrey Beeson

Jeffrey Beeson is an Assistant Professor at Oregon State University's College of Earth, Ocean, and Atmospheric Sciences. His research focuses on seafloor and subseafloor imaging to explore plate boundary tectonics, methane seepage, and submarine volcanism. He is actively involved in deep-sea exploration using advanced geophysical techniques, including multibeam sonar, AUV surveys, and seismic imaging. Beeson's work emphasizes understanding the dynamic processes at mid-ocean ridges, subduction zones, and hydrothermal systems. He has led and contributed to numerous expeditions, including studies of the Mid-Atlantic Ridge and Cascadia Margin. His recent projects investigate Axial Seamount's eruptive cycles, methane seep distributions, and the structural evolution of active margins. Beeson collaborates with international teams to integrate geodetic, geochemical, and geophysical data for comprehensive Earth system analysis.

Research interests include:

• Volcanism and magma dynamics at mid-ocean ridges
• Fluid flow and methane seepage in subduction zones
• Seafloor geodetic monitoring and deformation analysis
• Hydrothermal vent geochemistry and mineralization

His articles highlight advancements in seafloor mapping, eruption forecasting, and tectonic process modeling. Beeson's contributions to the CASIE21 seismic imaging project have improved understanding of Cascadia subduction zone structure. He is also involved in public outreach through ocean exploration initiatives like the R/V Elakha.
