Paleoecology and evolutionary response of planktonic foraminifera to the mid-Pliocene Warm Period and Plio-Pleistocene bipolar ice sheet expansion

Using results from the PlioMIP ensemble to investigate the Greenland Ice Sheet during the mid-Pliocene Warm Period

During an interval of the Late Pliocene, referred to here as the mid-Pliocene Warm Period (mPWP; 3.264 to 3.025 million years ago), global mean temperature was similar to that predicted for the end of this century, and atmospheric carbon dioxide concentrations were higher than preindustrial levels. Sea level was also higher than today, implying a significant reduction in the extent of the ice s...

Sensitivity of planktonic foraminifera to Mid-Pleistocene climate change in the SE Atlantic

In this paper we describe a record of planktonic foraminiferal relative abundance changes in Core T89-40 retrieved from the Walvis Ridge, SE Atlantic. The planktonic foraminiferal relative abundance changes reflect past (sub)surface water hydrography during the Mid-Pleistocene Transition. Statistical analysis shows that most variability in the planktonic foraminiferal relative abundance record ...

Plio-Pleistocene history of Ferrar Glacier, Antarctica: Implications for climate and ice sheet stability

The areal distribution and elevation of glacial drifts in Vernier Valley, southern Victoria Land, are used to reconstruct the PlioPleistocene history of upper Ferrar Glacier. Ne cosmogenic-nuclide analyses of surface cobbles on four moraines, Ferrar 1, 2, 3, and 4, provide age control. A minimum-age estimate for Ferrar Drifts calculated by assuming zero surface erosion indicates that the oldest...
