Commentary: Reframing Massive Carbon Input During the PETM and a Grand 66 Million Year Geoscience Puzzle

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Despite decades of research, hundreds of peer‐reviewed papers, and considerable relevance to Earth's future, the rapid global warming and tremendous CO2 input at the start of the Paleocene‐Eocene Thermal Maximum (PETM) remain highly debated.

Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

BioEssays, Volume 48, Issue 6, June 2026.
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution, ecology, life cycles, and ecosystem roles, highlighting this lineage as a model system for understanding life's resilience in a rapidly changing planet ...

Turnover of microbial cells, endospores, and organic carbon in ocean margin sediment affected by submarine landslides

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract The turnover rate of microbial cells drops steeply by increasing depth in the seabed, in accordance with the decreasing rate of organic matter mineralization. Bacterial endospore formation and germination may take place concurrently, yet their coupling to the mineralization rates during burial is poorly understood.

Neogene and quaternary planktonic foraminifer biostratigraphy and biochronology in Baffin Bay and the Labrador Sea

, 1989
During Ocean Drilling Program Leg 105, 11 holes were drilled in the Labrador Sea and Baffin Bay. Site 645 in Baffin Bay was drilled to a depth of 1147 meters below seafloor (mbsf); planktonic foraminifers were recovered in the upper 110.3 m and in a ...
