DeepMIP-Eocene-p2: Experimental design for Phase 2 of the early Eocene component of the CMIP7/PMIP7 Deep-time Model Intercomparison Project (DeepMIP-Eocene)

by
Maps comparing the Phase 1 (55 Ma), modern, and new Phase 2 (51 Ma) paleogeography reconstructions used in the DeepMIP-Eocene model experiments.

This paper outlines the experimental design for Phase 2 of DeepMIP-Eocene, a project that coordinates climate model simulations of the early Eocene, a period around 56–41 million years ago when global temperatures were far higher than today and carbon dioxide levels were much greater. The design updates the paleogeography, vegetation and carbon dioxide inputs used … Read more…

Congratulations to A/Prof Maria Seton, who has been awarded the S.W. Carey Medal from the Geological Society of Australia for her outstanding contribution and impact in the field of tectonics. The award was announced at the Australian Earth Sciences Convention in Melbourne, as part of the Geological Society of Australia’s 2026 national awards. A/Prof Seton … Read more…

Tectonics: Modeling Lithospheric Thickness Along the Conjugate South Atlantic Passive Margins Implies Asymmetric Rift Initiation

by

The lithospheric architecture of passive margins is crucial for understanding the tectonic processes that caused the breakup of Gondwana. We highlight the evolution of the South Atlantic passive margins by a simple thermal lithosphere-asthenosphere boundary (LAB) model based on onset and cessation of rifting, crustal thickness, and stretching factors. We simulate lithospheric thinning and select … Read more…
