Herein we present the results of a series of laboratory experiments conducted to delineate the relationship between dissolved organic phosphorus (DOP) utilization and organic matter production by the ...
Characterization of particulate organic matter in the water column of the South China Sea using a shotgun proteomic approach
Characterization of particulate organic matter water column of the South China Sea shotgun proteomic approach
2014/4/17
We characterized particulate organic matter (POM) collected from both the surface (41 m and 200 m) and mesopelagic layers (500 m and 1000 m) in the western South China Sea. By using a shotgun proteomi...
Illuminated darkness: Molecular signatures of Congo River dissolved organic matter and its photochemical alteration as revealed by ultrahigh precision mass spectrometry
Illuminated darkness Molecular signatures of Congo River organic matter its photochemical alteration ultrahigh precision mass spectrometry
2014/4/17
Congo River water was filtered and then irradiated for 57 d in a solar simulator, resulting in extensive photodegradation of dissolved organic matter (DOM). Whole-water (i.e., unfractionated) DOM was ...

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 ...
Terrestrial organic matter and light penetration: Effects on bacterial and primary production in lakes
Terrestrial organic matter light penetration on bacterial primary production in lakes
2014/4/17
We investigated productivity at the basal trophic level in 15 unproductive lakes in a gradient ranging from clear-water to brown-water (humic) lakes in northern Sweden. Primary production and bacteria...
