Short summary
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.

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.

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.

We present a dataset of 23032 fossil occurrences of marine organisms from the Late Miocene to the Early Pliocene (~11 to 3.6 million years ago) from the Mediterranean Sea. This dataset will allow us, for the first time, to quantify the biodiversity impact of the Messinian salinity crisis, a major geological event that possibly changed global and regional climate and biota.

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.

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.

How environmental change affects a species' phenotype is crucial for taxonomy and biodiversity assessments and for their application as paleoecological indicators. Morphometric data of a Neotropical ostracod species, as well as several climatic and hydrochemical variables, were used to investigate the link between morphology and environmental conditions. Temperature seasonality, annual precipitation, and chloride and sulphate concentrations were identified as drivers for ostracod ecophenotypy.

We study the variability in Mediterranean–Atlantic exchange, focusing on the surface Atlantic inflow across the mid-Pliocene warm period and the onset of the Northern Hemisphere glaciation, still unresolved by previous works. Oxygen isotope gradients between both sides of the Strait of Gibraltar reveal weak inflow during warm periods that turns stronger during severe glacials and the start of a negative feedback between exchange at the Strait and the Atlantic Meridional Overturning Circulation.

Isotopic signatures of ostracods from Florida correlate with their host water, implying a regional influence of temperature and precipitation. Calculated monthly configurations of a theoretical calcite formed in rivers were compared to ostracod isotope compositions. The data suggest a seasonal shell formation during early spring that is coupled to the hydrological cycle of the region. The surprising seasonality of the investigated ostracods is of importance for paleontological interpretation.

We present the first analysis of population structure and cohort distribution in a fossil oyster reef. Data are derived from Terrestrial Laser Scanning of a Miocene shell bed covering 459 m². A growth model was calculated, revealing this species as the giant oyster Crassostrea gryphoides was the fastest growing oyster known so far. The shell half-lives range around few years, indicating that oyster reefs were geologically short-lived structures, which were degraded on a decadal scale.

We report on a planned Trans-Amazon Drilling Project (TADP) that will continuously sample Late Cretaceous to modern sediment in a transect along the equatorial Amazon of Brazil, from the Andean foreland to the Atlantic Ocean. The TADP will document the evolution of the Neotropical forest and will link biotic diversification to changes in the physical environment, including climate, tectonism, and landscape. We will also sample the ca. 200Ma basaltic sills that underlie much of the Amazon.

Short summary
High-resolution analyses of paleoecological and geochemical proxies give insight into environmental processes and climate variations in the past on a timescale that is relevant for humans. This study, as the first of its kind, aims to resolve cyclic variations of nannofossil assemblages on a decadal to centennial scale in a highly sensitive Early Miocene (~17Ma) shallow marine setting. Our results indicate that solar variation played a major role in shaping short-term climate variability.
High-resolution analyses of paleoecological and geochemical proxies give insight into...
