Archaeal membrane lipids are widely used for paleotemperature reconstructions, yet these
molecular fossils also bear rich information about ecology and evolution of marine ammonia …

Paleotemperature proxy data form the cornerstone of paleoclimate research and are integral
to understanding the evolution of the Earth system across the Phanerozoic Eon. Here, we …

Abstract Model simulations of past climates are increasingly found to compare well with
proxy data at a global scale, but regional discrepancies remain. A persistent issue in …

One of Earth's most fundamental climate shifts, the greenhouse-icehouse transition 34
million years ago, initiated Antarctic ice sheet buildup, influencing global climate until today …

Abstract Large Oligocene Antarctic ice sheets co-existed with warm proximal waters offshore
Wilkes Land. Here we provide a broader Southern Ocean perspective to such warmth by …

Despite its major role in the Earth's climate regulation, the evolution of high-latitude ocean
dynamics through geological time remains unclear. Around Antarctica, changes in the …

​​​​​​​ Late Paleocene deposition of an organic-rich sedimentary facies on the
continental shelf and slope of New Zealand and eastern Australia has been linked to short …

Terrestrial organic carbon (TerrOC) acts as an important CO2 sink when transported via
rivers to the ocean and sequestered in coastal marine sediments. This mechanism might …

One of Earth's most fundamental climate shifts–the greenhouse-icehouse transition 34 Ma
ago–initiated Antarctic ice-sheet build-up, influencing global climate until today. However …

Abstract From the Eocene (~ 50 Ma) to the present-day, the dominant mode of ocean
circulation in the Southern Ocean transitioned from strong and large sub polar gyres to …
