The dataset spans 2006 to ongoing. These isotope ratios, nitrogen-15 and oxygen-18 relative to standard references, are used to trace the origin and cycling of nitrate in seawater. This dataset supports study of nitrogen cycling and nutrient sources in the California Current, for researchers studying ocean biogeochemistry.",
