Fig. 2

This figure illustrates the processes affecting DNA distribution, degradation and/or preferential preservation during the transitions from the pelagic to the benthic zones, and from the surface sediment to the deeper sediment. The approximate timescales of preservation of different fractions of the sediment record is also illustrated.
