About
Deniz Bombar is a marine microbial ecologist whose research centers on nitrogen fixation in the world’s oceans, with a particular focus on the oligotrophic North Pacific Subtropical Gyre. His pioneering work has advanced our understanding of how nitrogen-fixing microorganisms (diazotrophs) control marine productivity and nutrient cycles. Bombar’s most cited study (79 citations) introduced an “ecogenomic sensor” approach that revealed critical environmental controls on these keystone species, demonstrating how they reduce atmospheric dinitrogen to support new production in nutrient-poor waters. He also developed a free-drifting submersible incubation device to measure nitrogen fixation rates with unprecedented spatial resolution, addressing a major methodological challenge in field-based marine microbial ecology (24 citations). These innovations have provided researchers with powerful tools to study biogeochemical processes at finer scales. Bombar’s work is notable for bridging molecular techniques with in situ measurements, offering a more complete picture of how diazotrophs sustain ocean fertility. His contributions are essential for predicting how marine ecosystems will respond to climate-driven changes in nutrient availability.
