Deciphering the Variability in Mg/Ca and Stable Oxygen Isotopes of Individual Foraminifera [0.03%]
单个有孔虫Mg/Ca和稳定氧同位素变化的诠释

Foraminifera are commonly used in paleoclimate reconstructions as they occur throughout the world's oceans and are often abundantly preserved in the sediments. Traditionally, foraminifera-based proxies like δ18O and Mg/Ca are analyzed on p...
Widespread Warming Before and Elevated Barium Burial During the Paleocene-Eocene Thermal Maximum: Evidence for Methane Hydrate Release? [0.03%]
早古新世极热事件之前的普遍升温和事件期间的钡埋藏量升高：甲烷水合物释放的证据？
J Frieling,F Peterse,D J Lunt et al.
J Frieling et al.
Current climate change may induce positive carbon cycle feedbacks that amplify anthropogenic warming on time scales of centuries to millennia. Similar feedbacks might have been active during a phase of carbon cycle perturbation and global w...
Orbitally Forced Hyperstratification of the Oligocene South Atlantic Ocean [0.03%]

Pelagic sediments from the subtropical South Atlantic Ocean contain geographically extensive Oligocene ooze and chalk layers that consist almost entirely of the calcareous nannofossil Braarudosphaera. Poor recovery and the lack of precise d...

The Arctic cryosphere is changing and making a significant contribution to sea level rise. The Late Pliocene had similar CO2 levels to the present and a warming comparable to model predictions for the end of this century. However, the state...
High-Resolution Benthic Mg/Ca Temperature Record of the Intermediate Water in the Denmark Strait Across D-O Stadial-Interstadial Cycles [0.03%]
丹麦海峡D/O stadial-interstadial周期间Intermediate水体的高分辨率底栖镁钙温度记录

E G Sessford et al.
Dansgaard-Oeschger (D-O) climate instabilities that took place during Marine Isotope Stage 3 are connected to changes in ocean circulation patterns and sea ice cover. Here we explore in detail the configuration of the water column of the De...
Radiocarbon Age Offsets Between Two Surface Dwelling Planktonic Foraminifera Species During Abrupt Climate Events in the SW Iberian Margin [0.03%]
伊比利亚西南部边缘地带突然气候事件期间两种表层生活浮游有孔虫物种的碳十四年龄差异常态

This study identifies temporal biases in the radiocarbon ages of the planktonic foraminifera species Globigerina bulloides and Globigerinoides ruber (white) in a sediment core from the SW Iberian margin (so-called Shackleton site). Leaching...
