Organic petrological and biomarker investigations of core 9R from MARUM-MeBo70 Site PS104_20-2

Here we present organic petrological and biomarker investigations obtained from a 5 cm-thick mid-Cretaceous lignite layer in drill core 9R at MARUM-MeBo70 Site PS104_20-2 (73.57°S, 107.09°W; 946 m water depth) in late 2022 for reconstructing past wildfire activity near the South Pole. The site is lo...

Description
Summary:Here we present organic petrological and biomarker investigations obtained from a 5 cm-thick mid-Cretaceous lignite layer in drill core 9R at MARUM-MeBo70 Site PS104_20-2 (73.57°S, 107.09°W; 946 m water depth) in late 2022 for reconstructing past wildfire activity 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.
