Short summary
The lower branch of the Atlantic Meridional overturning consists of deep-water currents which flow within North Atlantic basins and deposit sediments known as contourite drifts. Fluctuations in the accumulation and the lithology of these drifts can help us understand deep-ocean circulation during past warm intervals. In this study we investigated the sedimentary archive of the Gardar Drift and identified a weakening in bottom current activity across the latest Miocene climatic warming.

Microscopic fossil shells preserved in the seabed serve as a vital window into Earth's climate history. Using advanced three-dimensional X-ray imaging, we discovered that these shells dissolve from the inside out immediately after burial. This process introduces difficult to detect errors that can bias historical climate records up to two degrees Celsius. Our new method allows for detection of these errors, improving the accuracy of our reconstructions and our understanding of Earth history.

Here we studied how tiny polar ocean plankton (foraminifera) breathe, using micro-sensors and 3D imaging to see if their respiration changes in responds to climate and environmental change. We found that the dominant polar species, Neogloboquadrina pachyderma, exhibits metabolic stability across large changes in temperature and ocean chemistry. This suggests its shell chemistry is not strongly affected by metabolism, supporting its use for reconstructing past polar ocean climates.

Between 44–34 million years ago, Earth's climate substantially cooled, leading to permanent Antarctic glaciation and major ocean changes. This caused high extinction rates amongst marine organisms, including the planktonic foraminifera. New data from the western Atlantic Ocean highlight how these organisms responded, where surface species declined and deeper species increased in abundance, reflecting shifts in vertical ocean structure during this key climate transition.

Pulleniatina is a genus of planktonic foraminifera used in biostratigraphy. Here, we illustrate typical specimens of Pulleniatina and the likely ancestor Neogloboquadrina acostaensis from International Ocean Discovery Program Site U1488. We present a novel integration of high-definition light microscopy images, X-ray microcomputed tomography data, and scanning electron microscope images to compare the six Pulleniatina species, supporting an evolutionary model with two diverging lineages.

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.

Here we compare the Mg / Ca and oxygen isotope signatures for 57 recent to fossil species of planktonic foraminifera for the last 15 Myr. We find the occurrence of lineage-specific offsets in Mg / Ca conservative between ancestor-descendent species. Taking into account species kinship significantly improves temperature reconstructions, and we suggest that the occurrence of Mg / Ca offsets in modern species results from their evolution when ocean properties were different from today's.

Deep Sea Drilling Project Site 407, near Iceland, offers a valuable 25-million-year record of planktonic foraminifera evolution from the Late Cenozoic. Species counts and ranges, assemblage changes, and biostratigraphic zones were identified. Key findings include the shifts in species dominance and diversity. Challenges include sediment gaps and missing biozone markers. We aim to enhance the Neogene–Quaternary Middle Atlas and improve the North Atlantic palaeoceanography and biostratigraphy.

We report on the rediscovery of Globigerina bollii, a planktonic foraminifer described by Cita and Premoli Silva (1960) in the Mediterranean Basin. We redescribe G. bollii as a valid species belonging to the genus Globoturborotalita. We report and summarise all the recordings of the taxon in the scientific literature. Then we discuss how the taxon might be a palaeogeographical indicator of the intermittent gateways between the Mediterranean Sea, Paratethys, and Indian Ocean.

Planktonic foraminifera are marine plankton that have a long and continuous fossil record. They are used for correlating and dating ocean sediments and studying evolution and past climates. This paper presents new information about Pulleniatina, one of the most widespread and abundant groups, from an important site in the Pacific Ocean. It also brings together a very large amount of information on the fossil record from other sites globally.

The microscopic shells of planktonic foraminifera accumulate on the sea floor over millions of years, providing a rich archive for understanding the history of the oceans. We examined an extinct group that flourished between about 63 and 32 million years ago using scanning electron microscopy and show that they were covered with needle-like spines in life. This has implications for analytical methods that we use to determine past seawater temperature and acidity.

Deep-living organisms are a major yet poorly known component of ocean biomass. Here we reconstruct the evolution of deep-living zooplankton and phytoplankton. Deep-dwelling zooplankton and phytoplankton did not occur 15 Myr ago, when the ocean was several degrees warmer than today. Deep-dwelling species first evolve around 7.5 Myr ago, following global climate cooling. Their evolution was driven by colder ocean temperatures allowing more food, oxygen, and light at depth.

The middle Miocene (15 Ma) was a period of global warmth up to 8 °C warmer than present. We investigate changes in ocean circulation and heat distribution since the middle Miocene and the cooling to the present using the cGENIE Earth system model. We create seven time slices at ~2.5 Myr intervals, constrained with paleo-proxy data, showing a progressive reduction in atmospheric CO2 and a strengthening of the Atlantic Meridional Overturning Circulation.

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.

We examined the planktonic foraminifera (calcareous zooplankton) from a section in northern Saudi Arabia. We found the assemblages to be diverse, well-preserved and of late Eocene age. Our study provides new insights into the stratigraphic ranges of many species and indicates that the late Eocene had a higher tropical/subtropical diversity of planktonic foraminifera than previously reported.

Short summary
Planktonic foraminifera are microscopic single-celled organisms populating world oceans. They have one of the most complete fossil records; thanks to their great abundance, they are widely used to study past marine environments. We analysed and measured series of foraminifera shells from Indo-Pacific sites, which led to the description of a new species of fossil planktonic foraminifera. Part of its population exhibits pink pigmentation, which is only the third such case among known species.
