The marine sediment core ARA03B-41GC (41GC) was retrieved from the Makarov (Podvodnikov) Basin in the western Arctic Ocean for paleoenvironmental reconstruction during the Quaternary. Physical and geochemical properties, granulometry, and stratigraphy of core 41GC were initially investigated and reported in a study published in Quaternary Geochronology (Park et al., 2020). Further investigation on mineralogical and paleomagnetic measurements of core 41GC was conducted to reconstruct cryospheric and oceanographic evolution in the Arctic Makarov Basin with a revised chronostratigraphy. The new research, titled "Cryospheric and oceanographic evolution in the Arctic Makarov Basin since the early Pleistocene revealed by bulk mineral assemblages", has been accepted by the scientific journal 'Paleoceanography and Paleoclimatology', 23rd April 2024. The dataset file, named "ARA03B 41GC data to PP.xlsx," contains information on Mn/Fe ratios (determined through X-ray fluorescence), inclination, sand fraction (>63 micron) contents, bulk mineral assemblage and their logratio, and clay mineral content (specifically smectite).
