Figure 2.

Simplified graphical representation of endmembers of the two remobilization models: (a) translational slide and (b) surficial sediment remobilization. For (a), the bulk OC ¹⁴C ages of event deposits are much older, because a higher amount of old carbon is remobilized. Note that, due to the exponential decay of ¹⁴C, the model is most sensitive when remobilizing young carbon, and less sensitive when remobilizing old or even blank carbon. In (b), the age shifts are expected to be small, due to remobilization of young surface sediment.
