Oceanic δ13C Fingerprints Caused by Laurentice Ice Sheet Discharges: Model‐Data Comparison During Heinrich Event 4

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract This study investigates the sensitivity of the oceanic circulation and δ13C ${\delta }^{13}C$ of the dissolved inorganic carbon to ice discharge events from the Laurentide ice sheet (LIS), using an isotope‐enabled and coupled climate–ice sheet model, and observations. The ice discharges are triggered by either reduced friction at the ice sheet‐

Ash grains of the 1991 Mt. Pinatubo eruption as a tracer in Rose Bengal stained deep sea agglutinated foraminifera: How old is Freddy? [PDF]

open access: yes, 2001
The use of volcanic ash particles (including dark-coloured grains) by agglutinated foraminifera that survived the 1991 eruption of Mt Pinatubo volcano provides a useful tracer to help determine growth rates and longevity in the deep sea. In the case of a

Lower Glacial Oxygen in the Eastern Equatorial Pacific Concentrated in the Deep Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Oxygen in the global oceans has declined since the 1960s, including in the Eastern Equatorial Pacific (EEP). Reconstructions of EEP glacial oxygenation help advance understanding of current and projected ocean deoxygenation. Previous estimates of the glacial oxygen deficient zones (ODZs) in the upper EEP are poorly constrained. Here we include

How Unusual Was the Paleocene‐Eocene Thermal Maximum?

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The Paleocene‐Eocene Thermal Maximum (PETM) was an extreme fluctuation of Earth's climate and a potential analog for future unmitigated anthropogenic climate change, but whose cause is debated. We show that fluctuations in Cenozoic benthic foraminiferal δ13 ${\delta }^{13}$C and δ18 ${\delta }^{18}$O follow a Laplace distribution. We present a

A revision of the Lower Cretaceous foraminiferal genus Falsogaudryinella from northwest Europe and Romania, and its relationship to Uvigerinammina [PDF]

open access: yes, 1995
We emend the definition of the foraminiferal genus Falsogaudryinella Bartenstein, 1977 based on observations of the type species, F. tealbyensis from the Barremian Lower Tealby Clay of Lincolnshire, U.K.
