The role of deep ocean circulation in setting glacial climates
JF Adkins - Paleoceanography, 2013 - Wiley Online Library
The glacial cycles of the Pleistocene involve changes in the circulation of the deep ocean in
important ways. This review seeks to establish what were the robust patterns of deep‐sea …

A transient rise in tropical sea surface temperature during the Paleocene-Eocene thermal maximum
The Paleocene-Eocene Thermal Maximum (PETM) has been attributed to a rapid rise in
greenhouse gas levels. If so, warming should have occurred at all latitudes, although …

Core top calibration of Mg/Ca in tropical foraminifera: Refining paleotemperature estimation
Optimal use of Mg/Ca as a paleotemperature proxy requires establishing calibrations for
different species of foraminifera and quantifying the influence of dissolution. To achieve this …
