| Summary: | This data file contains the IRD abundance, clay mineralogy, water content in Excel file 'Wang et al.xlsx (sheet: sedimentology)', and Sr-Nd isotopes in Excel file 'Wang et al.xlsx (sheet: Sr-Nd isotope)' in gravity core ANT34/A2-10 (LATITUDE: -67.036111 and LONGITUDE: -125.591944) from the Amundsen abyssal plain since 770 ka.Supplement to Jiakai Wang et al., Ocean-forced instability of the West Antarctic Ice Sheet since the mid-Pleistocene. Geochemistry Geophysics Geosystems (in review). ... : Abstract: Explore the West Antarctic Ice Sheet instability through Pleistocene glacial/interglacial cycles can provide fundamental constraints on interactions between the climate system and cryosphere. To achieve this goal, we provide continuous records of iceberg-rafted debris (IRD) content (including IRD counting and weight abundance), clay mineral content (including the smectite, kaolinite, illite, and chlorite), and clay mineralogy parameter (including Esquevin Index and full width at half maximum of the illite and smectite), supported by detrital Sr-Nd isotopes from the pronounced IRD peaks since mid-Pleistocene in gravity core ANT34/A2-10 (Latitude: -67.036111 and Longitude: -125.591944) from the Amundsen abyssal plain, Antarctic. The proxies of IRD and clay minerals are analyzed at the Key Laboratory of Marine Geology and Environment, Institute of oceanology Chinese academy of sciences. IRD proxy is determined by counting the number of particles in the 150 μm-2 mm fraction under a binocular microscope ... |
