Regional seawater δ18O records and global δ18O seawater-stack over the mid-Pleistocene transition
High-resolution seawater δ18O records, derived from coupled benthic foraminifera Mg/Ca and δ18O analyses, can be used to evaluate how global ice volume changed during the Mid-Pleistocene Transition (MPT, ~1250-600 ka ago). However, such seawater δ18O records are also influenced by regional hydrograp...
