Production of dissolved organic matter by phytoplankton and its uptake by heterotrophic prokaryotes in large tropical lakes
Production of dissolved organic matter by phytoplankton heterotrophic prokaryotes large tropical lakes
2014/7/10
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...

New insights mineralization dissolved organic matter central, intermediate deep water masses northeast North Atlantic
2014/4/2
An optimum multiparameter (OMP) analysis was applied to samples collected during a cruise in the northeast North Atlantic with the aim of objectively defining water mass realms and calculating water m...
Fluxes of dissolved aluminum and manganese to the Weddell Sea and indications for manganese co-limitation
Fluxes dissolved aluminum manganese to the Weddell Sea indications manganese co-limitation
2014/4/2
The trace metals aluminum (Al) and manganese (Mn) were studied in the Weddell Sea in March 2008.Concentrations of dissolved Al ([Al]) were slightly elevated (0.23–0.35 nmol L21) in the surface layer c...
Removal of dissolved inorganic carbon in the Yellow River Estuary
dissolved inorganic carbon Yellow River Estuary
2014/4/2
The Yellow River of China runs mainly through an arid and semiarid midlatitude region that has experienced
substantial anthropogenic and climatic change. This area includes the carbonate-rich Loess P...
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...

Metaproteomic characterization of dissolved organic matter in the water column of the South China Sea
Metaproteomic characterization dissolved organic matter water column South China Sea
2014/4/4
We characterized dissolved organic matter (DOM; < 0.7 μm in size) collected from the surface (10-m and 75-m) and bathypelagic (3000-m) layers in the South China Sea using the shotgun proteomic approac...
ntarctic krill as a source of dissolved organic carbon to the Antarctic ecosystem
ntarctic kril dissolved organic carbon Antarctic ecosystem
2014/4/4
The role of krill as a source of dissolved organic matter in the Southern Ocean was tested through a series of
experiments performed around the Antarctic Peninsula. These experiments revealed high bu...
