Research Interests

Dr. Oechel’s research focuses on developing and understanding the predictive capability of the interconnections of terrestrial, atmospheric, and marine systems on global change. He focuses primarily in the Arctic (Alaska, Russia), the Pacific Basin (Baja California Sur, Mexico, Indonesia), and the semi-arid ecosystems of Italy and San Diego. He incorporates a small research aircraft, eddy covariance towers, soil measurements, remote sensing, and modeling in his research programs. He leads a highly active research group with funding averaging $1.4 million/year, and he advises 2 Ph.D. students and several Master’s and undergraduate students.
