Millennial scale persistence of organic carbon bound to iron in Arctic marine sediments

Burial of organic material in marine sediments can sequester massive amounts of carbon, but the dynamics of this carbon sink are poorly understood. Here the authors investigate the so-called rusty carbon sink in Arctic shelf sediments, finding that organic carbon-iron associations are stable for 100...

Description
Summary:Burial of organic material in marine sediments can sequester massive amounts of carbon, but the dynamics of this carbon sink are poorly understood. Here the authors investigate the so-called rusty carbon sink in Arctic shelf sediments, finding that organic carbon-iron associations are stable for 1000 s of years.
