Figure 3: Close-Up of Events A,B and G,H (IMAGE) Kobe University Caption (a) Biogenic content on surface water (above) and anaerobic environment on the seabed (below). α and ε show the iceberg drift event in the North Pacific. Both arrows indicate the climate warming comprising four 200-year cycles. (b) is the data showing the Bond event in the Holocene Epoch. It resembles the climate warming at B, G, and H, but the Bond event is interpreted differently, as a climate cooling period.
