Fluorescent dissolved organic matter (FDOM) intensity (Parafac components and FDOM indices) in the surface water of the Mackenzie Delta Region during 4 expeditions from spring to fall in 2019 ...

Fluorescent dissolved organic matter intensity was measured with an Aqualog®. Measurements were corrected for inner-filter effects and for the Raman and Rayleigh scattering (Murphy et al., 2013; doi:10.1039/C3AY41160E). The different fluorescent components of DOM were isolated from combined signal b...

Description
Summary:Fluorescent dissolved organic matter intensity was measured with an Aqualog®. Measurements were corrected for inner-filter effects and for the Raman and Rayleigh scattering (Murphy et al., 2013; doi:10.1039/C3AY41160E). The different fluorescent components of DOM were isolated from combined signal by PARAFAC modeling using the “drEEM Toolbox” and following the recommendation of Murphy et al. (2013; doi:10.1039/C3AY41160E). The DOM components derived from PARAFAC modeling were compared with PARAFAC components from other studies through the OpenFluor database (Murphy et al., 2014; doi:10.1039/C3AY41935E). The coble-peaks indicate major fluorescent components (Coble 1996; doi:10.1016/0304-4203(95)00062-3) in marine FDOM EEMs (Excitation-Emission-Matrix). Peaks T represents protein-like compounds (tyrosine and tryptophane), peaks A and C are indicators of humic-like components whereas peak M was associated to marine humic-like fluorescence. The fluorescence index (FI) is calculated as the ratio of fluorescence ... : Empty cells = NA ...
