Marine record of late quaternary glacial-interglacial fluctuations in the Ross Sea and evidence for rapid, episodic sea level change due to marine ice sheet collapse [PDF]

open access: yes
Some of the questions to be addressed by SeaRISE include: (1) what was the configuration of the West Antarctic ice sheet during the last glacial maximum; (2) What is its configuration during a glacial minimum; and (3) has it, or any marine ice sheet ...

Provenance and Petrological Evolution of Sand Injection Complexes: Insights From Heavy Mineral Analysis in the Paleogene Forearc Succession of the San Joaquin Basin

open access: yesBasin Research, Volume 38, Issue 3, May–June 2026.
The study of heavy mineral assemblages with statistical analysis resolves provenance signatures and quantifies syn‐emplacement modification of sand injection complexes. Results demonstrate transformative petrological processes, including density‐dependent hydraulic sorting and mechanical grain degradation.

Paleoenvironmental Stasis for the Bioturbating Community During the Paleocene‐Eocene Thermal Maximum at the Southern Iberian Margin

open access: yesGeobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT During the Paleocene‐Eocene Thermal Maximum (PETM), there was an increase in global temperatures and emissions of isotopically depleted carbon, resulting in a negative carbon isotope excursion (CIE). This climatic event caused a widespread ocean deoxygenation, leading to substantial biotic turnover.
