AbstractA submersible chemical analyser (Scanner) was used to measure nitrate concentrations in situ to depths of nearly 2000 m. Nitrate anomalies with a vertical span of 5 m can be detected at lowering rates up to 40 m min-1. The nitrate concentrations measured in situ are in good agreement with hydrographic data collected by conventional means at the same location. The relative standard deviation of the analyses performed in situ is ±0.79%. The method can be easily extended to most other colorimetric analyses.
