A substantial export flux of particulate organic carbon linked to sinking dead copepods during winter 2007–2008 in the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean)
A substantial export flux particulate organic carbon linked sinking dead copepods during 2007–2008 the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean)
2014/4/2
In the Arctic Ocean, vertical fluxes of particulate organic carbon (POC) remain low during the dark winter period because POC fluxes are derived from photosynthetic production. Passively sinking dead ...
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...
Contribution of mycosporine-like amino acids and colored dissolved and particulate matter to sea ice optical properties and ultraviolet attenuation
amino acids colored dissolved
2014/4/16
In the Baltic Sea ice, the spectral absorption coefficients for particulate matter (PM) were about two times
higher at ultraviolet wavelengths than at photosynthetically available radiation (PAR) wav...
The role of effective discharge in the ocean delivery of particulate organic carbon by small, mountainous river systems
The role of effective discharge in the ocean delivery particulate organic carbon by small mountainous river systems
2014/4/16
Recent research has shown that small, mountainous river systems (SMRS) account for a significant fraction of the global flux of sediment and particulate organic carbon (POC) to the ocean. The enormous...
Seasonally varying nitrogen isotope biogeochemistry of particulate organic matter in Lake Kinneret, Israel
Seasonally varying nitrogen isotope particulate organic matter
2014/4/17
Large temporal variations in the nitrogen isotopic composition (d15N) of particulate organic matter (POM)
and dissolved inorganic nitrogen (DIN) species in Lake Kinneret occurred in response to seaso...
Evidence of prokaryotic metabolism on suspended particulate organic matter in the dark waters of the subtropical North Atlantic
prokaryotic metabolism particulate organic matter
2014/4/17
The distribution of prokaryotic abundance (PA), respiratory activity (ETS), heterotrophic production (PHP),
and suspended particulate (POM) and dissolved (DOM) organic matter was determined in the me...
