From the combination of orbital theory with benthic δ18O it has been suggested which obliquity cycles led to interglacials during the Quaternary. Here, we use a model-based deconvolution of this benthic δ18O record to calculate northern hemispheric land ice outside of Greenland, from which an alternative distribution of glacial and interglacial periods is defined.

结合轨道理论与底栖δ¹⁸O（benthic δ¹⁸O）的相关研究已提出，第四纪（Quaternary）时期的间冰期由黄赤交角周期（obliquity cycles）主导。本研究针对该底栖δ¹⁸O记录开展基于模型的反褶积（deconvolution）分析，以此估算格陵兰岛以外的北半球陆地冰量，并据此定义了一套独立的冰期与间冰期分布模式。[…]
