Timing of the descent into the last Ice Age determined by the bipolar seesaw
S Barker, P Diz - Paleoceanography, 2014 - Wiley Online Library
We present planktonic foraminiferal fauna and isotope records from the SE Atlantic that
highlight the nature of millennial‐scale variability over the last 100 kyr. We derive a …

Late Cretaceous–Neogene trends in deep ocean temperature and continental ice volume: Reconciling records of benthic foraminiferal geochemistry (δ18O and Mg …
We reconstruct trends in ice volume and deep ocean temperature for the past 108 Myr,
resolving variations on timescales of∼ 2 Myr and longer. We use a sea level record as a …

Coupling of CO2 and Ice Sheet Stability Over Major Climate Transitions of the Last 20 Million Years
The carbon dioxide (CO2) content of the atmosphere has varied cyclically between~ 180
and~ 280 parts per million by volume over the past 800,000 years, closely coupled with …

Pleistocene sea-surface temperature evolution: Early cooling, delayed glacial intensification, and implications for the mid-Pleistocene climate transition
The mid-Pleistocene climate transition (MPT) is defined by the emergence of high amplitude,
quasi-100ka glacial–interglacial cycles from a prior regime of more subtle 41kacycles. This …

Differential isotopic fractionation in benthic foraminifera and paleotemperatures reassessed
JC Duplessy, C Lalou, AC Vinot - Science, 1970 - science.org
Different species of benthic Foraminifera taken at the same level in an Atlantic core yielded
different oxygen isotopic values. It was therefore impossible to deduce paleotemperature …
