• Description:
  A study of two late Holocene sediment cores taken near an abandoned distributary of the Lafourche lobe in the Mississippi Delta aimed to quantify organic carbon (OC) accumulation rates and to establish their relationship with different types of deltaic deposits. Counterintuitively, we found that in several cases deposits with relatively low organic content are more efficient at burying carbon than peat. This has implications for coastal restoration by sediment diversions, showing the considerable potential of these landforms to bury carbon.
