Abstract : The goal of this research was to increase our understanding of the behavior of biogenic organic nitrogen compounds in the marine environment. Nitrogen is essential to the photosynthetic formation of life in natural waters and is one of the nutrients which can limit biological productivity. Thus, the regeneration of nutrient N from organic nitrogen compounds is extremely important in the estuarine, marine coastal, and upwelling systems which play such a major role in world biological production. This research placed particular importance on investigating the processes controlling the production, transition behavior, and ultimate fate of biogenic organic nitrogen compounds in the sea. Specifically, this work sought to measure the fate of organic nitrogen compounds dissolved in seawater and in large and small particles; to investigate cell-surface enzymatic oxidation of amino acids in seawater; to investigate the production of methane from methylated amines and other methylated compounds as a source of methane supersaturation in oxic surface ocean waters; and to compare intrinsic rates of heterotrophic uptake of organic compounds in oxic and anoxic water.
