Abstract:
Here we present n-alkanes from the mid-Cretaceous layer in drill core 9R and 10R at MARUM-MeBo70 Site PS104_20-2 (73.57°S, 107.09°W; 946 m water depth) for reconstructing past wildfire activity and vegetation near the South Pole. The site is located within the Pine Island cross-shelf trough in the Amundsen Sea Embayment (ASE), West Antarctica and was drilled during RV Polarstern Expedition PS104 in 2017. Ratios of C23/C31 and C23/C15 n-alkanes have been proposed as biomarker proxies for fossil Sphagnum dominated peat bogs.
