We explored how virtual tools can help students prepare for and reflect on outdoor learning in the Arctic. Using surveys from university courses in Svalbard, we found that digital field visits helped students feel more confident, better understand the landscape, and learn more effectively. These tools do not replace real fieldwork but make it more accessible and inclusive. Our research shows how technology can support hands-on learning in remote environments.

In this review article we present Svalbard’s unique geological archive, revealing its climate history over the last 540 million years. We uncover how this Arctic region recorded key global events, including the End-Permian Mass Extinction, and climate crises like the Paleocene–Eocene Thermal Maximum. The overall climate trend recorded in sedimentary successions in Svalbard is discussed in the context of global climate fluctuations and continuous drift of Svalbard from near equatorial to Arctic latitudes.

We present the digitalisation (i.e. textured outcrop and terrain models) of the Agardhfjellet Fm. cliffs exposed in Konusdalen West, Svalbard, which forms the seal of a carbon capture site in Longyearbyen, where several boreholes cover the exposed interval. Outcrop data feature centimetre-scale accuracies and a maximum resolution of 8 mm and have been correlated with the boreholes through structural–stratigraphic annotations that form the basis of various numerical modelling scenarios.

At UNIS, located at 78° N in Longyearbyen in Arctic Norway, we use digital outcrop models (DOMs) actively in a new course (
AG222 Integrated Geological Methods: From Outcrop To Geomodel) to solve authentic geoscientific challenges. DOMs are shared through the open-access Svalbox geoscientific portal, along with 360° imagery, subsurface data and published geoscientific data from Svalbard. Here we share experiences from the AG222 course and Svalbox, both before and during the Covid-19 pandemic.

Controlled Source Seismic data are essential for understanding the structure and composition of the subsurface. The paper presents a metadata model that allows the user to judge whether a data set is suitable for a specific re-use purpose. The model’s implementation as a metadata catalogue will provide FAIR and open metadata on assets of any legal status and make the assets available for multidisciplinary data integration on the European Plate Observing System (EPOS) research infrastructure.

The Carnian Pluvial Episode was a major climate event marked by a shift from arid to wetter conditions and major changes in biota. In this study, we analyze a sedimentary core from the Larne Basin, Northern Ireland, along with new data from South China. The results support volcanism as a key trigger of the event and indicate prolonged carbon cycle disruption, followed by increased delivery of coarse sediment, reflecting enhanced weathering and runoff.

Choosing samples from large sections of hard-rock cores often relies on preliminary chemical analyses, which can be limited and therefore misrepresentative of full chemical variability. This study adapts X-ray fluorescence core-scanning techniques for use on hard-rock basalt cores to outline a method that provides accurate chemical information in greater detail relative to traditional analytical methods. The presented workflow suggests significant contributions to new and legacy core research.

Analysis of Permian–Triassic bivalve fossils from the Dolomites reveals that apparent size reductions reflect faunal turnover, not within-species dwarfing. The extinction eliminated most species, with smaller new species dominating the recovery. Whereas survivors showed no size body change. The subsequent size rebound occurred in two pulses: growth within survivors (late Griesbachian) and evolution of larger taxa (early Spathian), refining interpretations of the “Lilliput effect.”

We use regional 2D seismic to reconstruct the Late Miocene to Pleistocene ice sheet history of the Northeast Greenland continental shelf. Regional borehole correlations show that the first ice stream advance across the shelf occurred around 6.4 Ma. Subsequently, a marked change in ice sheet configuration towards intensified cross-shelf ice streaming post-dates 4.1 Ma, possibly correlating to the intensification of the Northern Hemisphere glaciations.

We analysed Miocene dinocyst taxa and organic particle assemblages along a distal–proximal transect in the North Sea Basin. Based on distal and shallow marine successions, we reconstruct depositional changes across the Miocene Climatic Optimum (MCO; ~16.9–14.7 Ma) and use dinocysts as palaeoclimate proxies. Additionally, we provide five GDGT-derived sea surface temperature data points that support our dinocyst-based climate interpretation.

Many academic laboratories worldwide process environmental samples for analysis of membrane lipid molecules of archaea, for the reconstruction of past environmental conditions. However, the sample workup scheme involves many steps, each of which has a risk of contamination or bias, affecting the results. This paper reviews steps involved in sampling, extraction and analysis of lipids, interpretation and archiving of the data. This ensures reproducible, reusable, comparable and consistent data.

We use plant wax compound specific stable isotopes to investigate how ancient Antarctic vegetation adapted to glacial conditions 23 million years ago. We find plants became less water efficient to prioritise photosynthesis during short, harsh growing seasons. Ecosystem changes also included enhanced aridity, and a shift to a stunted, low elevation vegetation. This shows the adaptability of ancient Antarctic vegetation under atmospheric CO2 conditions comparable to modern.

Fires are limited in year-round wet climates (tropical rainforests; too wet), and in year-round dry climates (deserts; no fuel). This concept, the intermediate-productivity gradient, explains the global pattern of fire activity. Here we test this concept for climate states of the Jurassic (~190 Myr ago). We find that the intermediate-productivity gradient also applies in the Jurassic despite the very different ecosystem assemblages, with fires most frequent at times of high seasonality.

The discovery of cold-water glendonite pseudomorphs in sediments deposited during the hottest part of the Cenozoic poses an apparent climate paradox. This study examines their occurrence, association with volcanic sediments, and speculates on the timing and extent of cooling, fitting this with current understanding of global climate during this period. We propose that volcanic activity was key to both physical and chemical conditions that enabled the formation of glendonites in these sediments.

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.

Floods draining beneath an ice cap are hazardous events that generate six different short- or long-lasting types of seismic signals. We use these signals to see the collapse of the ice once the water has left the lake, the propagation of the flood front to the terminus, hydrothermal explosions and boiling in the bedrock beneath the drained lake, and increased water flow at rapids in the glacial river. We can thus track the flood and assess the associated hazards better in future flooding events.

There are periods in Earth’s history when huge volumes of magma are erupted at the Earth’s surface. The gases released from volcanic eruptions and from sediments heated by the magma are believed to have caused severe climate changes in the geological past. We use a variety of volcanic and climatic tracers to assess how the North Atlantic Igneous Province (56–54 Ma) affected the oceans and atmosphere during a period of extreme global warming.

We provide a sea surface temperature record from the Labrador Sea (ODP Site 647) based on organic geochemical proxies across the late Eocene and early Oligocene. Our study reveals heterogenic cooling of the Atlantic. The cooling of the North Atlantic is difficult to reconcile with the active Atlantic Meridional Overturning Circulation (AMOC). We discuss possible explanations like uncertainty in the data, paleogeography and atmospheric CO2 boundary conditions, model weaknesses, and AMOC activity.

How much of the West Antarctic Ice Sheet will melt and how quickly it will happen when average global temperatures exceed 2 °C is currently unknown. Given the far-reaching and international consequences of Antarctica’s future contribution to global sea level rise, the SWAIS 2C Project was developed in order to better forecast the size and timing of future changes.

The Collisional Orogeny in the Scandinavian Caledonides project provides insights into the deep structure and bedrock of a ca. 400 Ma old major orogen to study deformation processes that are hidden at depth from direct access in modern mountain belts. This paper describes the successful operations at the second site. It provides an overview of the retrieved geological section that differs from the expected and summarises the scientific potential of the accomplished data sets and drill core.

In this paper, we present new sedimentological, geochemical, and mineralogical data exploring the environmental response to climatic and volcanic impact during the Paleocene–Eocene Thermal Maximum (~55.9 Ma; PETM). Our data suggest a rise in continental weathering and a shift to anoxic–sulfidic conditions. This indicates a rapid environmental response to changes in the carbon cycle and temperatures and highlights the important role of shelf areas as carbon sinks driving the PETM recovery.

At UNIS, located at 78° N in Longyearbyen in Arctic Norway, we use digital outcrop models (DOMs) actively in a new course (
AG222 Integrated Geological Methods: From Outcrop To Geomodel) to solve authentic geoscientific challenges. DOMs are shared through the open-access Svalbox geoscientific portal, along with 360° imagery, subsurface data and published geoscientific data from Svalbard. Here we share experiences from the AG222 course and Svalbox, both before and during the Covid-19 pandemic.

Short summary
Geologists can decipher the past climates and thus better understand how future climate change may affect the Earth's complex systems. In this paper, we report on a workshop held in Longyearbyen, Svalbard, to better understand how rocks in Svalbard (an Arctic archipelago) can be used to quantify major climatic shifts recorded in the past.
