Abstract:
We analysed:
1. TOC and CNS contents on sediment core PS69/274-1 and calculated the C/N-ratio and carbonate content of the individual sample depths.
2. a specific biomarker lipid called IPSO25 in sediment core PS69/274-1 from the western Amundsen Sea continental shelf, Antarctica, alongside a phytoplankton biomarker (dinosterol) for reconstructing palaeo-sea ice coverage. We further applied the PIPSO25 approach for semi-quantitative sea ice reconstructions.
