Abstract:
This data set was collected during Polarstern cruise ARKXXII/2 in 2007. It contains data on dissolved organic carbon concentrations, lignin phenol concentration and optical properties measured as absorbance and fluorescence from insitu sensors (Haardt fluorometer) and laboratory measurements on discrete water samples (absorbance scans and fluorescence scans-EEMs).
Keyword(s):
