Enhanced Terrestrial Carbon Export From East Antarctica During the Early Eocene Open
Terrestrial organic carbon (TerrOC) acts as an important CO 2 sink when transported via rivers to the ocean and sequestered in coastal marine sediments. This mechanism might help to modulate atmospheric CO 2 levels over short‐ and long‐ ti…

The enigma of Oligocene climate and global surface temperature evolution Open
Significance During the Eocene, high-latitude regions were much warmer than today and substantial polar ice sheets were lacking. Indeed, the initiation of significant polar ice sheets near the end of the Eocene has been closely linked to g…

Oligocene Biomarker Temperature Estimates from ODP Hole 154-929A and DSDP Hole 75-516F Open
Falling atmospheric CO2 levels led to cooling through the Eocene and the expansion of Antarctic ice sheets close to their modern size near the beginning of the Oligocene, a period of poorly documented climate. Here we present the first rec…

Antarctic Ice Sheet variability across the Eocene-Oligocene boundary climate transition Open
Sensitive ice sheets Why did the Antarctic Ice Sheet begin to grow 34 million years ago, and what does that have to do with us? Galeotti et al. studied a marine sediment core recovered from just off the coast of Antarctica (see the Perspec…
