Introduction
16
This data set contains all geochemical data used in this study, listed per sample
17
(ts01.docx). Bold data are generated in this study, other data is compiled from
18
previous publications (Table 2). In fs01.pdf all measured redox sensitive elements are
19
plotted for the studied sites.
20
1. ts01.docx all geochemical data used in study.
21
1.1 Column “Leg”, the number of the leg of the Deep Sea Drilling Project (DSDP) or
22
Ocean Drilling Program (ODP) of which the drilled site is part of.
23
1.2 Column “Site”, the DSDP or ODP site the studied samples originate from.
24
1.3 Column “Hole”, sometimes multiple holes are drilled per DSDP or ODP site, this
25
indicates from which hole the studied samples originate from.
26
1.4 Column “Core”, the core from which the studied sample originates.
27
1.5 Column “Section”, the section of the core from which the studied sample
28
originates.
29
1.6 Column “top depth (cm)”, the upper limit of the sampled interval.
30
1.7 Column “base depth (cm)”, the lower limit of the sampled interval.
31
1.8 Column “Sample depth (mbsf)”, the average sample depth, i.e. the average of the
32
top depth and base depth, in meters below seafloor (mbsf).
33
1.9 Column “TOC (%)”, the total organic carbon content (TOC).
34
1.10 Column “δ13Corg/TOC (‰ VPDB)”, the stable isotopic composition of carbon in
35
organic matter or total organic carbon content, measured versus the international
36
standard, the Vienna Peedee Belemnite (VPDB).
37
1.11 Column “Corg/Ptot (mol/mol)”, the molar ratio of organic carbon and phosphorus.
38
1.12 Column “P (ppm)”, the concentration of phosphorus in parts per million.
39
1.13 Column “Al (%)”, the concentration of aluminum.
40
41
1.14 Column “Fe (%)”, the concentration of iron
42
1.15 Column “Mo (ppm)”, the concentration of molybdenum in parts per million.
43
1.16 Column “V (ppm)”, the concentration of vanadium in parts per million.
44
1.17 Column “Mn (ppm)”, the concentration of manganese in parts per million.
45
1.18 Column “Zn (ppm)”, the concentration of zinc in parts per million.
46
1.19 Column “Ni (ppm)”, the concentration of nickel in parts per million.
47
1.20 Column “Cu (ppm)”, the concentration of copper in parts per million.
48
1.21 Column “Cr (ppm)”, the concentration of chromium in parts per million.
49
1.22 Column “S (%)”, the concentration of sulphur.

(e). Grey shades highlight the OAE2-interval, based on the positive excursion in
53
δ13Corg/ δ13CTOC and elevated TOC content, with the subdivision into different phases
54
of the CIE marked by an “A”, “B” or “C” after Kuypers et al. (2002). mbsf: meters
55
below seafloor.
