We explore new methods for ice-rafted debris detection in marine sediment cores to detect past climate changes and ice sheet dynamics. Traditional IRD detection methods are destructive and time-consuming. To alleviate this problem, we utilize non-destructive imaging techniques core material from the Indian Ocean. While promising, we found contamination to be an issue. Machine learning identifies density and chemical differences, but rigorous testing is needed to avoid false positives.

Our study provides guidelines improving the reuse of marine microfossil assemblage data, which are valuable for understanding past ecosystems and environmental change. Based on a survey of 113 researchers, we identified key data attributes required for effective reuse. Analysis of a selection of datasets available online reveals a gap between the attributes scientists consider essential and the data currently available, highlighting the need for clearer data documentation and sharing practices.

It is known that coral reefs were absent in the central Indo-Pacific during the Early Pliocene. This study uses a new temperature record based on TEX86H biomarkers from the Coral Sea between 11–2 Ma to show a 2 °C cooling in the central Indo-Pacific during the Late Miocene Cooling (7–5.4 Ma). This cooling triggered changes in terrestrial input, ocean circulation, and temperature. These multiple stressors could have caused reef collapses across the central Indo-Pacific.

The Benguela Upwelling System is a region in the SE Atlantic Ocean of high biological productivity. It comprises several water masses such as the Benguela Current, South Atlantic Central Water, and Indian Ocean Agulhas waters. We analyzed planktonic foraminifera from IODP Sites U1575 and U1576 to characterize water masses and their interplay in the Pleistocene. This defined changes in the local thermocline, which were linked to long-term Benguela Niño- and Niña-like and deglaciation events.

Differences exist in International Ocean Discovery Program (IODP) sediment lithification depending on the coring tool used. Advanced piston corers (APCs) display less pronounced lithification compared to extended core barrels (XCBs) of the same formation. The difference stems from the destruction of early cements between sediment grains and an
acoustic compactioncaused by the piston-core pressure wave. XCB cores provide a more accurate picture of the lithification of the original formation.

The Leeuwin Current transports warm water along the western coast of Australia: from the tropics to the Southern Hemisphere midlatitudes. Therewith, the current influences climate in two ways: first, as a moisture source for precipitation in southwestern Australia; second, as a vehicle for Equator-to-pole heat transport. In this study, we study sediment cores along the Leeuwin Current pathway to understand its ocean–climate interactions between 4 and 2 Ma.

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.

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.

Bowl-shaped spirorbid microbialite bioherms formed during the late Middle Miocene (Sarmatian) in the central Paratethys Sea under a warm, arid climate. The microbialites and the surrounding sediment document a predominance of microbial activity in the shallow marine environments of the sea at that time. Modern microbialites are not analogues for these unique structures, which reflect a series of growth stages with an initial “start-up stage”, massive “keep-up stage” and termination of growth.

Short summary
Coral larvae can drift through ocean currents between coral reefs, establishing connectivity, which plays an important role in coral reef resilience. However, larval transport is chaotic. We simulate coral spawning events across the tropical southwest Indian Ocean for almost three decades, and find that larval transport can vary massively from day-to-day. This variability is largely random, and this introduces a lot of uncertainty in connectivity predictions.

Ocean currents transport things over large distances across the ocean surface. Predicting this transport is key for tackling many environmental problems, such as marine plastic pollution and coral reef resilience. However, doing this requires a good understanding ocean currents, which is currently lacking. Here, we present and validate state-of-the-art simulations for surface currents in the southwestern Indian Ocean, which will support future marine dispersal studies across this region.

We identified the provenance, (post)depositional history, weathering conditions and hydroclimate that formed the detrital and authigenic silicates and soil carbonates of the Valley of Lakes sediments in Central Asia during the Cenozoic (~34 to 21 Ma). Aridification pulses in continental Central Asia coincide with marine glaciation events and are caused by Cenozoic climate forcing and the exhumation of the Tian Shan, Hangay and Altai mountains, which reduced the moisture influx by westerly winds.

Short summary
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.
