Raymond Najjar

I am Raymond Najjar, Professor of Oceanography in the Department of Meteorology and Atmospheric Science with a joint appointment in the Department of Geosciences. I teach about and conduct research on a variety of topics in oceanography and related sciences. My early research focused on large-scale, open-ocean biogeochemistry, particularly the cycling of nutrients (nitrogen, phosphorus, and silicon), oxygen, and carbon. A few years after arriving at Penn State in 1993, I became interested in coastal issues, such as eutrophication, hypoxia, and sea-level rise. I worked on numerous regional climate impact assessments, including one that was part of the first National Climate Assessment. I am mainly a data analyst, but I also use numerical models and remote sensing. Occasionally, I am lucky enough to go to sea, and have conducted studies in the Sargasso Sea and coastal waters of Antarctica and the Eastern United States.
