Jordon Beckler, Ph.D.

Assistant Research Professor




Dr. Jordon Beckler directs the Geochemistry and Geochemical Sensing Lab at FAU Harbor Branch Oceanographic Institute and is also an I-SENSE faculty fellow.

Dr. Beckler’s primary research interests include developing and applying autonomous biogeochemical sensing technologies to constrain fundamental elemental cycling mechanisms and rates in redox environments. These findings can be applied to inform hydrologic or climate models, environmental restoration efforts, or resource management decisions.  For example, he is currently developing in situ electrochemical techniques to measure concentrations, transformations, and fluxes of trace metals, carbon, nutrients, and sulfides between sediments and the water column of marine and estuarine environments such as the locally environmentally stressed Indian River Lagoon.  In addition, he is adapting chromatographic and spectrophotometric analytical techniques for employment by autonomous surface and underwater vehicles, for example, to monitor of the inherent optical properties of terrestrial and marine waters. He has participated extensively in oceanographic expeditions and has used Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs), and Deep Submersible Vehicles (DSVs), in the Atlantic (Carolina slope, Congo River fan), Gulf of Mexico (Louisiana slope), and Pacific Oceans (East Pacific Rise hydrothermal fields, Eastern Tropical North Pacific oxygen-minimum zone). Dr. Beckler is also strongly committed to STEM outreach for high school and undergraduate students and employs low-cost sensors and embedded microcontrollers to engage students on topics relating to ocean observing and environmental stewardship. Dr. Beckler is currently a Gulf Research Program Early Career Fellow with the National Academies of Science, Engineering, and Medicine. He is a former Staff Scientist and Program Manager of the Ocean Technology Research Program at Mote Marine Laboratory in Sarasota, Florida and courtesy faculty member at the University of South Florida Sarasota-Manatee. He holds a Ph.D. in Chemical Oceanography and a minor in Inorganic Chemistry from the Georgia Institute of Technology (2014).
