Although the flux of dissolved organic carbon (DOC) through freshwaters is nearly
equivalent to the net carbon uptake of all terrestrial ecosystems, uncertainty remains about …

We performed a meta-data analysis to investigate the importance of event based fluxes to
DOC export from forested watersheds. A total of 30 small eastern United States forested …

Wildfires and incomplete combustion of fossil fuel produce large amounts of black carbon.
Black carbon production and transport are essential components of the carbon cycle …

Nine cruises were conducted on a seasonal basis from 2013 to 2015 to investigate the
spatial distribution and seasonal variability of δ13C and δ15N in particulate organic matter …

Small rivers draining mountain islands are important in the transfer of terrestrial particulate
organic carbon (POC) to the oceans. This input has implications for the geochemical …

We investigated the export of particulate organic matter (POM) to the ocean by two
contrasting small, mountainous rivers, the Umpqua and Eel Rivers, by collecting suspended …

Burial of biogenic silica (bSitotal) in high sedimentation rate continental margins remains
highly uncertain. Cosmogenic 32Si (t1/2~ 140 years) can be used to trace the fates of …

Abstract The Magdalena River has the greatest length (1612 km) and drainage area
(257400 km 2) of any river system in Colombia, and its watershed occupies 24% of the …

Ocean color imagery from MODIS (Moderate Resolution Imaging Spectroradiometer)
onboard the Aqua platform is used to characterize the interannual variability of turbid river …

Watershed classification has long been a key tool in the hydrological sciences, but few
studies have been extended to biogeochemistry. We developed a combined hydro …
