Long-term Evolution of Global Cenozoic Sea Surface Temperature:
An Evidence from Lipid Biomarker Paleothermometry
Why do we need to construct a high-resolution, long-term, continuous, global sea surface temperature (SST) curve?
Our understanding of the Earth’s climatic evolution during the Cenozoic era have been collectively developed through several long-term paleoclimate reconstruction records using several proxies, e.g., the 50-million-year deep-ocean temperature and global ice volumes from benthic foraminiferal Mg/Ca (Lear et al., 2000), the 65-million-year deep-ocean benthic foraminifera δ18O (Zachos et al., 2001) and global-mean surface temperature (Hansen et al., 2013), or the 40-million-year atmospheric CO2 from alkenone (Zhang et al., 2013). However, long-term, continuous SST records at such intervals have yet been well established. As SST is also one of the most important key factors reflecting global climate and ocean dynamics, we believe the long-term global Cenozoic SST will provide new insights for the long-term variability of global climate and ocean dynamics.
