We present initial results from a 650 m long core of Late Triasssic to Early Jurassic (190–202 Myr) sedimentary strata from the Cheshire Basin, UK, which is shown to be an exceptional record of Earth evolution for the time of break-up of the supercontinent Pangaea. Further work will determine periodic changes in depositional environments caused by solar system dynamics and used to reconstruct orbital history.

40.5 million years ago, Earth's climate warmed, but it is unknown why. Enhanced volcanism has been suggested, but this has not yet been tied to a specific region. We explore an increase in volcanism in Iran. We dated igneous rocks and compiled ages from the literature. We estimated the volume of igneous rocks in Iran in order to calculate the amount of CO2 that could have been released due to enhanced volcanism. We conclude that an increase in volcanism in Iran is a plausible cause of warming.

Volcanoes where tectonic plates drift apart pose eruption and earthquake hazards. Underground waters are difficult to track. Underground microbial life is probably plentiful but unexplored. Scientists discussed the idea of drilling two boreholes in the Okataina Volcanic Centre, New Zealand, to unravel the connections between volcano, faults, geotherms, and the biosphere, also integrating mātauranga Māori (Indigenous knowledge) to assess hazards and manage resources and microbial ecosystems.

Seven million years ago, the marine gateway connecting the Mediterranean Sea with the Atlantic Ocean started to close, and, as a result, water circulation ceased. To find out how this phenomenon affected the fish living on the surface and at the bottom of the Mediterranean Sea, we examined the changes in the isotopic composition of fish earstones. Although fish living at the surface fared pretty well, bottom-water fish starved and eventually became extinct in the Mediterranean.

We have studied the geochemistry of benthic foraminifera (micro-fossils) from a sediment core from the Red Sea. Our data show that the circulation and carbon cycling of the Red Sea during the last glacial period responded to high-latitude millennial-scale climate variability and to the orbital influence of the African–Indian monsoon system. This implies a sensitive response of the Red Sea to climate changes.

Climatic and associated hydrological changes controlled the aeolian versus fluvial transport processes and the composition of the sediments in the central Red Sea through the last ca. 200 kyr. We identify source areas of the mineral dust and pulses of fluvial discharge based on high-resolution grain size, clay mineral, and geochemical data, together with Nd and Sr isotope data. We provide a detailed reconstruction of changes in aridity/humidity.

Conservation of decorated caves is highly dependent on airflows and is correlated to the rock formation permeability. We present the first conceptual model of flows around the Paleolithic decorated Cosquer coastal cave (SE France), quantify air permeability and show how its variation affects water levels inside the cave. This study highlights that airflows may change in karst unsaturated zone in response to changes in the water cycle and may thus be affected by climate change.

Alkenones and glycerol dialkyl glycerol tetraether lipids (GDGTs) are common biomarkers for past water temperatures. In high latitudes, determining temperature reliably is challenging. We analyzed 33 Southern Ocean sediment surface samples and evaluated widely used global calibrations for both biomarkers. For GDGT-based temperatures, previously used calibrations best reflect temperatures >5° C; (sub)polar temperature bias necessitates a new calibration which better aligns with modern values.

Tectonic processes are complex and often difficult to understand due to the limitations of surface or subsurface data. One such process is inversion tectonics, which means that an area initially developed in an extension (such as the opening of an ocean) is reversed to compression (the process leading to mountain building). In this research, we use a laboratory method (analogue modelling), and with the help of a sandbox, we try to better understand structures (folds/faults) related to inversion.

This study analyzes the diversity of benthic foraminifera at the range expansion front of the invasive species Amphistegina lobifera in Corfu (central Mediterranean). The species has been suggested to impact local diversity and community structures, and our results confirm these effects as soon as A. lobifera exceeds a specific abundance threshold (> 20 %). Nevertheless, we found that the study area reveals an overall high biodiversity that can be attributed to its unique location.

Productivity increases in Lake Kälksjön sediments during the last 9600 years are likely driven by the progressive millennial-scale winter warming in northwestern Europe, following the increasing Northern Hemisphere winter insolation and decadal to centennial periods of a more positive NAO polarity. Strengthened productivity variability since ∼5450 cal yr BP is hypothesized to reflect a reinforcement of NAO-like atmospheric circulation.

Seafloor instruments at the bottom of the Sea of Marmara recorded disturbances caused by earthquakes, addressing the minimum magnitude that may be recorded in the sediment. A magnitude 4.7 earthquake caused turbidity but little current. A magnitude 5.8 earthquake caused a mudflow and strong currents that spread sediment on the seafloor over several kilometers. However, most known earthquake deposits in the Sea of Marmara spread over larger zones and should correspond to larger earthquakes.

U–Pb dating by the in situ laser ablation mass spectrometry (LA-ICPMS) technique requires reference materials of the same nature as the samples to be analysed. Here, we have explored the suitability of using carbonate materials as a reference for sulfates, since there is no sulfate reference material. The results we obtained are satisfactory, and thus, from now on, the sulfates can also be analysed.

The paper covers the aspects related to changes in carbon, nitrogen, and phosphorus (C, N, P) external loads; their transformations in the coastal zone; changes in organic matter production (eutrophication) and remineralization (oxygen availability); and the role of sediments in burial and turnover of C, N, and P. Furthermore, this paper also focuses on changes in the marine CO2 system, the structure of the microbial community, and the role of contaminants for biogeochemical processes.

Past export production in the southeast Pacific and its link to Patagonian ice dynamics is unknown. We reconstruct biological productivity changes at the Pacific entrance to the Drake Passage, covering the past 400 000 years. We show that glacial–interglacial variability in export production responds to glaciogenic Fe supply from Patagonia and silica availability due to shifts in oceanic fronts, whereas dust, as a source of lithogenic material, plays a minor role.

This paper is a step towards understanding the basal peat ecosystem beneath the North Sea. Plant remains followed parallel sequences. Methane concentrations were low with local exceptions, with the source likely being trapped pockets of millennia-old methane. Microbial community structure indicated the absence of a biofilter and was diverse across sites. Large carbon stores in the presence of methanogens and in the absence of methanotrophs have the potential to be metabolized into methane.

Many of the world's hydrocarbon resources are found in rifted sedimentary basins. Some rifts experience multiple phases of extension and inversion. This results in complicated oil and gas generation, migration, and entrapment histories. We present examples of basins in the Western Desert of Egypt and the western Black Sea that were inverted multiple times, sometimes separated by additional phases of extension. We then discuss how these complex deformation histories impact exploration campaigns.

This paper demonstrates that the recently discovered cable bacteria are capable of using a mineral, known as siderite, as a source for the formation of iron oxides. This work also demonstrates that the activity of cable bacteria can lead to a distinct subsurface layer in the sediment that can be used as a marker for their activity.

Inversion tectonics has been studied in detail by both academic researchers and industry experts around the world for the last 30 years. Inverted structures provide important traps for petroleum exploration which can be categorized into two end-member modes of evolution. This paper attempts to provide a brief synoptic view of inversion tectonics from the point of view of the petroleum industry, emphasizing the main subsurface challenges of understanding this structural geology phenomenon.

We studied the removal of phosphorus (P) and nitrogen (N) in the eutrophic Stockholm archipelago (SA). High sedimentation rates and sediment P contents lead to high P burial. Benthic denitrification is the primary nitrate-reducing pathway. Together, these mechanisms limit P and N transport to the open Baltic Sea. We expect that further nutrient load reduction will contribute to recovery of the SA from low-oxygen conditions and that the sediments will continue to remove part of the P and N loads.

Cyanobacterial blooms represent a threat to the Baltic Sea ecosystem, causing deoxygenation of the bottom water. In order to understand the natural versus anthropogenic factors driving these blooms, it is necessary to study long-term trends beyond observations. We have produced a record of cyanobacterial blooms since 1860 using organic molecules (biomarkers) preserved in sediments. Cyanobacterial blooms in the Baltic Sea are likely mainly related to temperature variability.

The paper presents the response of benthic foraminiferal communities to seasonal absence of oxygen coupled with the presence of hydrogen sulfide, considered very harmful for several living organisms.
Our results suggest that the foraminiferal community mainly responds as a function of the duration of the adverse conditions.
This knowledge is especially useful to better understand the ecology of benthic foraminifera but also in the context of palaeoceanographic interpretations.

This work highlights that iron (Fe) dynamics plays a key role in the release of alkalinity from sediments, as exemplified for the Baltic Sea. It furthermore demonstrates that burial of Fe sulfides should be included in alkalinity budgets of low-oxygen basins. The sedimentary alkalinity generation may undergo large changes depending on both organic matter loads and oxygen conditions. Enhanced release of alkalinity from the seafloor can increase the CO2 storage capacity of seawater.

Here we present new numerical simulations showing that Holocene submarine landslides along the North Anatolian Fault in the Aegean Sea may have triggered tsunamis higher than the ones expected for earthquake sources. During the Holocene, the shore facing the city of Alexandroupoli may have been impacted by tsunami up to 1.65 m at the coastline.

We show that burial rates of phosphorus (P) in an estuary in the northern Baltic Sea are very high. We demonstrate that at high sedimentation rates, P retention in the sediment is related to the formation of vivianite. With a reactive transport model, we assess the sensitivity of sedimentary vivianite formation. We suggest that enrichments of iron and P in the sediment are linked to periods of enhanced riverine input of Fe, which subsequently strongly enhances P burial in coastal sediments.

Recording the precise timing and sequence of events is essential for understanding rapid climate changes and improving climate model predictive skills. Here, we precisely assess the relative timing between ocean and atmospheric changes, both recorded in the same deep-sea core over the last 45 kyr. We show that decreased mid-depth water mass transport in the western equatorial Atlantic preceded increased rainfall over the adjacent continent by 120 to 980 yr, depending on the type of climate event.

Oxygen deficiency is a major environmental problem deteriorating seafloor habitats especially in the coastal ocean with large human impact. Here we apply a wide set of chemical and physical analyses to a 1500-year long sediment record and show that, although long-term climate variability has modulated seafloor oxygenation in the coastal northern Baltic Sea, the oxygen loss over the 20th century is unprecedentedly severe, emphasizing the need to reduce anthropogenic nutrient input in the future.

Coastal and submarine landslides occur on average every 30–50 years at the western tip of the Gulf of Corinth. These landslides trigger tsunamis and thus represent a significant hazard. We realized an inventory of the submarine landslide deposits in the western Gulf. Six large events are identified in the last 130 000 years. Such sliding events likely generated large tsunami waves in the whole Gulf of Corinth, possibly larger than those reported in historical sources.

We show that post-depositional formation of iron(II) phosphate as vivianite strongly alters the phosphorus record in sediments of the Bornholm Basin (Baltic Sea). These minerals began to precipitate in the lake sediments just after the last lake–marine transition ~ 7.5 kyr BP, migrated downwards and are now a stable feature. Formation of vivianite may affect sedimentary phosphorus records in other systems as well. This should be considered when using such records to reconstruct past environments.

In Lake Grevelingen, a coastal ecosystem, foraminifera experience important temporal variations in oxygen concentration and in pore water manganese. The high resolution of LA-ICP-MS allows us to analyse the chambers of foraminiferal shells separately and to obtain signals from a series of calcification events. We estimate the variability in Mn/Ca observed within single shells due to biomineralization and show that a substantial part of the signal is related to environmental variability.

We present reconstructions of paleotemperature, paleosalinity, and paleoecology from the Little Belt (Site M0059) over the past ~ 8000 years and evaluate the applicability of numerous proxies. Conditions were lacustrine until ~ 7400 cal yr BP. A transition to brackish–marine conditions then occurred within ~ 200 years. Salinity proxies rarely allowed quantitative estimates but revealed congruent results, while quantitative temperature reconstructions differed depending on the proxies used.

By combining detailed geochemical analyses with diagenetic modeling, we provide new insights into how methane dynamics may strongly overprint burial records of iron, sulfur and phosphorus in marine systems subject to changes in organic matter loading or water column salinity. A better understanding of these processes will improve our ability to read ancient sediment records and thus to predict the potential consequences of global warming and human-enhanced inputs of nutrients to the ocean.

This paper investigates the climatic response to orbital forcing through the analysis of an ensemble of simulations covering a late Miocene precession cycle. Including orbital variability in our model–data comparison reduces the mismatch between the proxy record and model output. Our results indicate that ignoring orbital variability could lead to miscorrelations in proxy reconstructions. The North African summer monsoon's sensitivity is high to orbits, moderate to paleogeography and low to CO2.

This study looks at the combined impacts of hypoxia and acidification, two major environmental stressors affecting coastal systems, in a seasonally stratified basin. Here, the surface water experiences less seasonality in pH than the bottom water despite higher process rates. This is due to a substantial reduction in the acid-base buffering capacity of the bottom water as it turns hypoxic in summer. This highlights the crucial role of the buffering capacity as a modulating factor in pH dynamics.

Deciphering coseismic offsets from creeping is a key point for an active fault behavior. In a subaqueous setting, coseismic offsets of the seafloor may be sealed off by earthquake-triggered sediments. Along the limit of a pull-apart basin in the Sea of Marmara, successive vertical offsets (up to 1.4m) are deduced from the thicknesses of homogenites which seal-off created scarps. During a 2kyr period, coseismic seafloor offsets are dominant, representing potential tsunami hazards.

Annually laminated sediments from the NE Bering Sea reveal a decadal-scale correlation to Greenland ice core records during termination I, suggesting an atmospheric teleconnection. Lamination occurrence is tightly coupled to Bølling-Allerød and Preboreal warm phases. Increases in export production, closely coupled to SST and sea ice changes, are hypothesized to be a main cause of deglacial anoxia, rather than changes in overturning/ventilation rates of mid-depth waters entering the Bering Sea.

An integrated campaign of drilling around Asia and Australia was conducted from 2013 to 2016 to reconstruct the monsoon climate. The results provide relatively continuous records spanning the last 24 myr. Asia has shown a steady drying since the late Miocene, while Australia has become wetter. The monsoons are affected by the tectonics of Asia and surrounding seas, as well as orbital forcing, resulting in diachronous evolution of continental climate, ocean currents, and the marine biosphere.

The IODP scientific ocean drilling program drilled into the sediments of the Bengal–Nicobar submarine fan system west of Sumatra, Indonesia. Within the cores, a large piece of fossilized wood was discovered, 9 million years in age and buried beneath 800 m of sediment; it is thought to be the largest wood fragment found in scientific ocean drilling boreholes. The wood is believed to be a species of flowering plant and may have originated from the north, east, or even as a result of a tsunami.

The Toarcian Oceanic Anoxic Event (T-OAE) was cored at Colle di Sogno and Gajum in the Lombardy Basin (northern Italy), where pelagic successions guarantee a continuous record of this paleoenvironmental perturbation. The Sogno and Gajum cores recovered high-quality sediments deposited prior to, during, and after the T-OAE. Ongoing research is devoted to reconstructing the marine ecosystem dynamics and resilience under short- and long-term perturbations analogous to current global changes.

Short summary
BlackGate seeks to MSP drill a transect to study the impact of dramatic hydrologic change in Mediterranean–Black Sea connectivity by recovering the Messinian to Holocene (~ 7 Myr) sedimentary sequence in the North Aegean, Marmara, and Black seas. These archives will reveal hydrographic, biotic, and climatic transitions studied by a broad scientific community spanning the stratigraphic, tectonic, biogeochemical, and microbiological evolution of Earth’s most recent saline and anoxic giant.
