It is well established that greenhouse conditions prevailed during the Cretaceous Period (~
145–66 Ma). Determining the exact nature of the greenhouse-gas forcing, climatic warming …

Abstract The Coniacian-Santonian (CS) was a time of differentiation in marine
sedimentation, characterized by organic carbon (OC)-rich black shales and carbonates …

A compilation of foraminiferal stable isotope measurements from southern high latitude
(SHL) deep-sea sites provides a novel perspective important for understanding Earth's …

Marine gateways play a critical role in the exchange of water, heat, salt and nutrients
between oceans and seas. As a result, changes in gateway geometry can significantly alter …

Abstract The Late Cretaceous 'greenhouse'world witnessed a transition from one of the
warmest climates of the past 140 million years to cooler conditions, yet still without …

Understanding the behavior of the global climate system during extremely warm periods is
one of the major themes of paleoclimatology. Proxy data demonstrate that the equator-to …

Abstract Neodymium isotopic compositions (143 Nd/144 Nd or ε Nd) have been used as a
tracer of water masses and lithogenic inputs to the ocean. To further evaluate the …

Abstract Recent models of South Atlantic opening history focus on early plate divergence by
incorporating intracontinental deformation, which is poorly constrained. Aiming to avoid the …

Oceanic anoxic events (OAEs) are large-scale events of oxygen depletion in the deep ocean
that happened during pre-Cenozoic periods of extreme warmth. Here, to assess the role of …

We present early Cretaceous to present paleobathymetric reconstructions and quantitative
uncertainty estimates for the South Atlantic, offering a strong basis for studies of …
