Transformation fate of microphytobenthos carbon subtropical shallow subtidal sands A 13C-labeling study
2014/4/2
Microphytobenthos (MPB) in photic sediments are highly productive but the fate of this production remains uncertain. Over 33 d, tracing of 13C from added bicarbonate in subtropical shallow subtidal sa...
Carbon cycling hysteresis in permeable carbonate sands over a diel cycle: Implications for ocean acidification
Carbon cycling hysteresis permeable carbonate sands over a diel cycle ocean acidification

The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
2014/4/4
Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...
