North Sea well sites 22/10a−4 and E−8X (this study) generally display higher values than Fur and Svalbard7. Carbon isotope excursion (CIE) step 2 is shown as a dashed line and does not co-occur with a Hg or Hg/TOC spike in the sections. Core 22/10a−4 has previously been interpreted to have been partially impacted by transported carbon26. Bulk sediment δ13CTOC is reported as ‰ VPDB, Vienna PeeDee Belemnite.
