Bounding cross-shelf transport time and degradation in Siberian-Arctic land-ocean carbon transfer

The fate of terrestrial organic carbon in marine sediments is debated due to large uncertainties in its degradation during transport. Here, using compound-specific radiocarbon dating of terrestrial biomarkers, the authors show that transport across the East Siberian Arctic shelf takes 3600 ± 300 yea...

Description
Summary:The fate of terrestrial organic carbon in marine sediments is debated due to large uncertainties in its degradation during transport. Here, using compound-specific radiocarbon dating of terrestrial biomarkers, the authors show that transport across the East Siberian Arctic shelf takes 3600 ± 300 years.
