Latitudinal Heterogeneity in South Asian Monsoon Changes Since the Last Glacial Maximum Revealed by Ganga–Brahmaputra Vegetation Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 11, November 2026.
Abstract Future changes in South Asian climate are expected to amplify flooding and drought, yet the spatial and temporal variability of the South Asian monsoon (SAM) under different climate regimes remains poorly constrained. Here, we present a new marine pollen record from the Bay of Bengal (BoB), informing on the vegetation of the Ganges‐Brahmaputra

The calcareous nannofossil Prinsiosphaera achieved rock-forming abundances in the latest Triassic of western Tethys: consequences for the δ¹³C of bulk carbonate [PDF]

Biogeosciences, 2013
The onset of pelagic biomineralization was a milestone in the history of the long-term inorganic carbon cycle: as soon as calcareous nannofossils became major limestone producers, the pH and supersaturation state of the global ocean were stabilized (the ...

Life After Impact: Paleobathymetric Gradients in Post‐K/Pg Nannoplankton Boom‐Bust Successions

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Cretaceous/Paleogene (K/Pg) bolide impact ∼66 Ma caused the near‐demise of calcareous nannoplankton–key primary producers and major components of the biological pump that exports organic and inorganic carbon to the deep sea. Despite their ecological significance, resolving the exact impact of nannoplankton's mass extinction on ecosystem ...

New Constraints on the Onset of Antarctic Glaciation From Combined Radiogenic Hafnium and Neodymium Isotopes

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The drawdown of atmospheric CO2 likely triggered Antarctic glaciation during the Eocene‐Oligocene Transition (34 Ma). Accurately constraining this shift from “greenhouse” to an “icehouse” climate is essential for understanding global carbon cycle dynamics.
