Fig. 2: Stacked paleohydrological proxy records from the West Mediterranean, West Africa and West-Central African regions spanning the last 70 kyr.

From: Occurrence of Heinrich stadials in the West Mediterranean and West African regions and their connections to atmospheric circulation changes

Fig. 2

a West Mediterranean MAP stack (mm/yr, LOESS = 0.015). b–e West African records: b Stack of dust% (normalized, inverted axis, LOESS = 0.01). c Stack of 230Th-normalized dust flux (normalized, inverted axis, LOESS smoothing = 0.02). d Humidity Index record. e Stack of δD leaf waxes (normalized, inverted axis, LOESS = 0.015). (f) West-Central African MAP stack (mm/yr, LOESS = 0.015). Gray shadings show the standard deviation for each record. The yellow vertical shades show the age-range of the Heinrich Stadials (HS6-HS1) and Younger Dryas (YD). In graphs a and f, the yellow stars on the vertical axes and discontinuous gray horizontal lines indicate the recent average annual precipitation in both regions (West Mediterranean = 444 mm/yr; West-Central Africa = 1629 mm/yr. See section Stacked paleohydrological proxy results and Supplementary Fig. 1).
