Journal ArticleDOI
Trends, Rhythms, and Aberrations in Global Climate 65 Ma to Present
TL;DR: This work focuses primarily on the periodic and anomalous components of variability over the early portion of this era, as constrained by the latest generation of deep-sea isotope records.
Journal ArticleDOI
Paleotemperatures and ice volume of the past 27 Myr revisited with paired Mg/Ca and 18O/16O measurements on benthic foraminifera
TL;DR: This paper explored the applicability of paired Mg/Ca and 18O/16O measurements on benthic foraminifera from Southern Ocean site 747 to paleoceanographic reconstructions on pre-Pleistocene timescales.
Journal ArticleDOI

TL;DR: In this article, 13 laboratories from the USA and Europe participated in an intercomparison study of Mg/Ca and Sr/Ca measurements in foraminifera, including five planktonic species from surface sediments from different geographical regions and water depths.
Journal ArticleDOI
Application of benthic foraminiferal Mg/Ca ratios to questions of Cenozoic climate change
TL;DR: In this article, the authors investigated the evolution of Cenozoic climate and ice volume as evidenced by the oxygen isotopic composition of seawater (δ18Osw) derived from benthic foraminiferal Mg/Ca ratios to constrain the temperature effect contained in foraminIFeral δ18 O values.
Application of Benthic Foraminiferal Mg/Ca Ratios to Questions of Cenozoic Climate Change
