From: Multiple carbon cycle mechanisms associated with the glaciation of Marine Isotope Stage 4
From top to bottom we show a Taylor Glacier CO2, b Taylor Glacier δ13C-CO2, c Taylor Glacier CH4 with comparison to EPICA Dronning Maud Land (EDML) and North Greenland Ice Core Project (NGRIP) CH484,85, d mean ocean temperature derived from noble gas measurements of Taylor Glacier ice cores12, e EPICA Dome C (EDC) Na+ proxy for Antarctic sea ice extent57, f South Atlantic TN057−14PC authigenic U proxy for deep ocean oxygenation50, g South Atlantic TN057−14PC opal flux42, h Western Boundary Undercurrent sortable silt circulation tracer16, i South Atlantic TN057-21 alkenone flux productivity proxy52, j EDC dust flux59, and k Deep Atlantic total dissolved inorganic carbon reconstruction49. Age models are consistent with AICC 201211,29,86.
