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 on the mineralization of dissolved organic matter in central, intermediate, and deep water masses of the northeast North Atlantic
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...
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...
Biogeneration of chromophoric dissolved organic matter by bacteria and krill in the Southern Ocean
chromophoric dissolved organic matter bacteria krill the Southern Ocean
2014/4/17
Chromophoric dissolved organic matter (CDOM), the optically active fraction of dissolved organic matter, is primarily generated by pelagic organisms in the open ocean. In this study,we experimentally ...

2014/4/16
Incubation experiments with axenic cultures of four common phytoplankton species of the generaChaetoceros,Skeletonema, Prorocentrum, and Micromonaswere performed to test for the production of fluoresc...
Dissolved organic matter and bacterial production and respiration in the sea-surface microlayer of the open Atlantic and the western Mediterranean Sea
Dissolved organic matter bacterial production respiration the sea-surface microlayer Atlantic the western Mediterranean Sea
2014/4/21
The sea-surface microlayer (SML) is the boundary layer between the ocean and the atmosphere. We measured bacterial production and respiration along with dissolved organic carbon (DOC), nitrogen (DON),...
The influence of dissolved organic carbon on bacterial phosphorus uptake and bacteria-phytoplankton dynamics in two Minnesota lakes
dissolved organic carbon bacterial phosphorus uptake bacteria-phytoplankton dynamics two Minnesota lakes
2014/4/21
The balance of production in any ecosystem is dependent on the flow of limiting nutrients into either the autotrophic or heterotrophic components of the food web. To understand one of the important co...
