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 …

BS Cramer, KG Miller, PJ Barrett… - Journal of Geophysical …, 2011 - Wiley Online Library
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

AK Tripati, CD Roberts, RA Eagle - science, 2009 - science.org
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

EL McClymont, SM Sosdian, A Rosell-Melé… - Earth-Science …, 2013 - Elsevier
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 …

Eocene bipolar glaciation associated with global carbon cycle changes

A Tripati, J Backman, H Elderfield, P Ferretti - Nature, 2005 - nature.com
The transition from the extreme global warmth of the early Eocene 'greenhouse'climate∼ 55
million years ago to the present glaciated state is one of the most prominent changes in …

Orbital forcing of the marine isotope stage 9 interglacial

CH Stirling, TM Esat, K Lambeck, MT McCulloch… - Science, 2001 - science.org
Milankovitch orbital forcing theory has been used to assign time scales to many
paleoclimate records. However, the validity of this theory remains uncertain, and …

Millennial-scale changes in North Atlantic circulation since the last glaciation

TM Marchitto Jr, WB Curry, DW Oppo - Nature, 1998 - nature.com
Ocean circulation is closely linked to climate change on glacial–interglacial and shorter
timescales. Extensive reorganizations in the circulation of deep and intermediate-depth …

North Pacific response to millennial‐scale changes in ocean circulation over the last 60 kyr

T Kiefer, M Sarnthein, H Erlenkeuser… - …, 2001 - Wiley Online Library
Foraminifera‐based sea surface temperature estimates in the northwest Pacific (Ocean
Drilling Program Site 883; 51° N) varied by 4° C on millennial timescales over the last …

Magnitudes of sea-level lowstands of the past 500,000 years

EJ Rohling, M Fenton, FJ Jorissen, P Bertrand… - Nature, 1998 - nature.com
Existing techniques for estimating natural fluctuations of sea level and global ice-volume
from the recent geological past exploit fossil coral-reef terraces or oxygen-isotope records …
