#RiverDeltas are hot spots of #BiogeochemicalCycling. Understanding sources and driving factors of #DissolvedOrganicMatter (DOM) in river deltas is important for evaluating the role of river deltas in regulating #GlobalCarbonFlux. Yuan Cui et al. analyzed the #SpectroscopicProperties of soil DOM in both freshwater and tidal areas of the #YellowRiverDelta.

#Krill help support a #diversity of #MarineLife, but they also play a major role in #BiogeochemicalCycling by trapping #carbon in the #DeepSea — something that benefits even those of us that live far from its frigid waters.

While krill have been spotted thousands of feet deep on the #seafloor, they also come up to the surface of the water to feed on #algae that absorb #CarbonDioxide.
