Sentences with phrase «pliocene paleotemperature»

Although there is limited evidence of ice - rafted debris in the Arctic from the Miocene and into the Eocene, suggesting some continental glaciation (Stickley et al., 2009; St. John and Krissek, 2002), empirical evidence suggests that widespread Northern Hemisphere glaciation did not occur until 2.75 Ma (Ravelo et al., 2004), which is substantiated by recent Pliocene paleotemperature SST estimates near Svalbard between 10 and 18 °C (Robinson, 2009).

Refined paleotemperature estimates from the annual growth rings and δ18O of cellulose in fossil wood also showed considerably warmer TSTs in the Arctic during the Pliocene, yielding a MAT of — 0.5 ± 1.9 °C and a ΔMAT of ∼ 19 °C (Table 1).
