Figure 4: Cross-phase analysis of climate variables with eccentricity.

From: Persistent 400,000-year variability of Antarctic ice volume and the carbon cycle is revealed throughout the Plio-Pleistocene

Figure 4

Lead (positive) and lag (negative) with respect to the 400-kyr filter of eccentricity. Surface-air temperature in green, Site 846 SSTs33 in red, Eustatic sea level in blue, AIS volume in orange, Mediterranean stack planktonic δ13C data13 in grey and Leg 138 benthic δ13C data13 in black, with the dashed line showing the apparent disappearance of 400-kyr cycles13.
