(Table 3) Factors of changes in lipid concentration between the different stratigraphic layers in core ABC26

Values are calculated as such that the sample with more TOC is divided by the sample which less TOC, leading mostly to values >1. POtop, top of postsapropelic unit (core top); PObot, bottom of postsapropelic layer; OStop, top of oxidised layer (manganese marker bed); OSbot, bottom of the oxidised sapropel; VStop, top of the visible sapropel; VSbot, bottom of the visible sapropel; PRtop, top of the subsapropelic layer (presapropel); oo=infinitive due to absence of compound in the more oxidised sample; and no value due to absence of compound in both samples.
