Downcore median calendar ages modeled using 16 radiocarbon ages (triangles in the Core Depth axis)44 in the Bacon Package87 with the Marine20 calibration88. The timing of the Heinrich Stadials is supported by elevated Fe/Ca and Ti/Ca ratios100 representing enhanced dust deposition during continental aridity77.
