Abstract :
Nitrate and H2S concentrations were measured in 31 water samples from 4 CTD Stations in the North Atlantic and 234 water samples from all basins of the Baltic Sea, using standard wet chemical laboratory methods in parallel with a commercial in situ absorption spectrometer. The parameters for fitting the absorption spectra to sets of calibration spectra were optimized as a preparation to use the commercial instrument in situ.
