Fig. 2: Mn/Fe composition and age of the studied ferromanganese crust.
From: Enhanced deep Southern Ocean stratification during the lukewarm interglacials
a Mn/Fe ratios with age contours marking glacial intervals (ages in ka). The glacial age contours always correspond to relatively low Mn/Fe ratios, while relatively high Mn/Fe ratios reflect interglacials. b and c show 2D/3D age images for the selected areas indicated in a.
