The spectral slope coefficient of chromophoric dissolved organic matter (S275–295) as a tracer of terrigenous dissolved organic carbon in river-influenced ocean margins
The spectral slope coefficient chromophoric dissolved organic matter S275–295 tracer of terrigenous dissolved organic carbon river-influenced ocean margins
2014/4/4
The present study demonstrates that the spectral slope coefficient of chromophoric dissolved organic matter (CDOM) between 275 nm and 295 nm (S275–295) can be used as a tracer of the percent terrigeno...

2014/4/4
Comparisons of the concentrations and compositions of dissolved organic matter (DOM) between the lower Mississippi River (MR) and its distributary, the Atchafalaya River (AR), indicated a strong influ...
High concentrations of mycosporine-like amino acids and colored dissolved organic matter in the sea surface microlayer off the Iberian Peninsula
High concentrations of mycosporine-like amino acids colored dissolved organic matter the sea surface microlayer off Iberian Peninsula
2014/4/16
Mycosporine-like amino acids (MAAs), phytoplankton pigments, and inherent optical properties were analyzed in sea surface microlayer (SSM), near-surface (0–2 m), and subsurface (0–110 m) samples from ...
Dissolved Organic Matter in the Ocean: A Controversy Stimulates New Insights
Carbon emissions atmosphere ocean dissolved organic matter carbon sequestration Marine geochemistry
2015/7/6
Containing as much carbon as the atmosphere, marine dissolved organic matter is one of Earth's major carbon reservoirs. With invigoration of scientific inquiries into the global carbon cycle, our igno...
