Short summary
We examine trends in biosiliceous fluxes and isotopic records in the North and South Atlantic, South Pacific, and Indian oceans during two climatic and biotic events: the Latest Danian Event (LDE; ~62.2 Ma) and the Early Late Palaeocene Event (ELPE; ~59.2 Ma). Our results show a peak during the LDE and following the ELPE.

A global-scale compilation of Palaeogene diatomite occurrences shows how palaeogeographic and palaeoceanographic changes impacted diatom accumulation, especially in the middle Eocene. Diatomite deposition dropped in epicontinental seas between ~ 46 and ~ 44 Ma, while diatom accumulation began around 43.5 Ma in open-ocean settings. The compilation also shows an indirect correlation between Palaeogene climate fluctuations and diatomite deposition in shallow-marine and freshwater environments.

We provide a new compilation of rates at which sediments deposited in the deep sea over the last 70 million years. We highlight a bias, linked to the drilling process, that makes it more likely for high rates to be recovered for younger sediments than for older ones. Correcting for this bias, the record shows, contrary to prior estimates, a more stable history, thus providing some insights on the past mismatch between physico-chemical model estimates and observations.

We studied diatom fossils from the Southern Ocean to understand how ocean productivity changed ~40–30 million years ago during a major climate shift marked by the onset of permanent Antarctic glaciation and global cooling. We found striking shifts in diatom productivity, revealing critical changes in ocean circulation and nutrient supply. Our results show how these microscopic organisms may have influenced climate, acting as a geological force that shaped global climate over time.

Export productivity is part of the global carbon cycle, influencing the climate system via biological pump. About 34 million years ago, the Earth's climate experienced a climate transition from a greenhouse state to an icehouse state with the onset of ice sheets in Antarctica. Our study shows important productivity events in the Southern Ocean preceding this climatic shift. Our findings strongly indicate that the biological pump potentially played an important role in that past climate change.

We provided novel insights into the behaviour of a major upwelling cell between 15 and 8.5 million years ago. To study changing conditions, we apply a combination of geochemical and paleoecological parameters to characterize the nutrient availability and subsequent utilization by planktonic primary producers. These changes we then juxtapose with established records of contemporary monsoon wind intensification and changing high-latitude processes to explain shifts in the plankton community.

This study evaluates the use of automatic classification using AI on eight closely related radiolarian species of the genus Podocyrtis based on MobileNet CNN. Species belonging to Podocyrtis are useful for middle Eocene biostratigraphy. Numerous images of Podocyrtis species from the tropical Atlantic Ocean were used to train and validate the CNN. An overall accuracy of about 91 % was obtained. Additional Podocyrtis specimens from other ocean realms were used to test the predictive model.

Short summary
We reconstruct the history of biogenic opal accumulation through the early to middle Paleogene in the western North Atlantic. Biogenic opal accumulation was controlled by deepwater temperatures, atmospheric greenhouse gas levels, and continental weathering intensity. Overturning circulation in the Atlantic was established at the end of the extreme early Eocene greenhouse warmth period. We also show that the strength of the link between climate and continental weathering varies through time.

Short summary
The synthesis of Palaeogene deep-sea diatom-bearing sediment occurrences indicates that the deposition of diatom-bearing sediments is mainly controlled by nutrient availability and ocean circulation in the Atlantic, Pacific, and Indian oceans. Comparison with shallow marine diatomites suggests that the peak in the number of diatom-bearing sites in the Atlantic is indirectly related to tectonic reorganizations that caused the cessation of shallow marine diatomite deposition between ~46 and ~44 Ma.
The synthesis of Palaeogene deep-sea diatom-bearing sediment occurrences indicates that the...
