Picocyanobacteria and deep-ocean fluorescent dissolved organic matter share similar optical properties [PDF]
Nature Communications, 2017 The sources of marine chromophoric dissolved organic matter and associated fluorescent DOM (FDOM) remain unclear. Here, the authors demonstrate that picocyanobacteria release FDOM similar to typical fluorescent signals found in the ocean, and are likely ...

Estimating submarine groundwater discharge in Jeju volcanic island (Korea) during a typhoon (Kong-rey) using humic-fluorescent dissolved organic matter-Si mass balance [PDF]
Scientific Reports, 2021 We examined the residence time, seepage rate, and submarine groundwater discharge (SGD)-driven dissolved nutrients and organic matter in Hwasun Bay, Jeju Island, Korea during the occurrence of a typhoon, Kong-rey, using a humic fluorescent dissolved ...

Linkages among fluorescent dissolved organic matter, dissolved amino acids and lignin-derived phenols in a river-influenced ocean margin [PDF]
Frontiers in Marine Science, 2015 Excitation emission matrix (EEM) fluorescence spectroscopy coupled with parallel factor analysis (PARAFAC) is commonly used to investigate the dynamics of dissolved organic matter (DOM). However, a lack of direct comparisons with known biomolecules makes

Sedimentary supply of humic-like fluorescent dissolved organic matter and its implication for chemoautotrophic microbial activity in the Izu-Ogasawara Trench [PDF]
Scientific Reports, 2021 Microbial community structure in the hadal water is reported to be different from that in the upper abyssal water. However, the mechanism governing the difference has not been fully understood.
