A recently commercialized sensor, the In Situ Ultraviolet Spectrophotometer (ISUS), can determine seawater nitrate concentrations rapidly. Procedures for incorporating ISUS data within routine conductivity, temperature, and depth (CTD) profiling studies have not been described. Using a CTD system with an ISUS, vertical hydrographic profiles with nutrient concentrations were determined at 42 sites across the shelf break on the Beaufort Sea, Alaska. Key data processing steps included elimination… CONTINUE READING
