Figure 7. Correlation of Cretaceous and Cenozoic climate oscillations at various latitudes in the Northern and Southern Hemispheres: a - conventional average annual temperatures in Siberia from oxygen isotope and Ca/Mg data [Gol'bert, 1987]; b - relative temperature changes in northern Siberia based on sedimentologic and paleontologic data [Velichko et al., 1994]; c - relative temperature changes in mountain regions of NE Asia based on paleobotanical data [Krasheninnikov et al., 1990]; d - relative changes of January temperature in Northeast Siberia [Velichko et al., 1994]; e - relative temperature changes in the Koryak Highland and Kamchatka based on paleobotanical and foraminifer data [Fot'janova and Serova, 1994]; f - temperatures in the Northwest Pacific based on oxygen isotope and paleobotanical data [Zakharov et al., 1999a]; g - surface water temperatures at low latitudes based on oxygen isotope data [Douglas and Woodruff, 1981]; h - surface water temperatures at middle latitudes in the Indian Ocean based on oxygen isotope data [Clarke and Jenkyns, 1999]; i - relative temperature changes in Antarctic Peninsula based on geochemical and other data [Dingle and Lavelle, 1998].
