Session 1.1. Hotspots and intraplate magmas: Mantle sources, magmatic processes and metasomatism.

This session invites contributions that explore the mantle geochemistry, petrology and dynamics of intraplate volcanism both in oceanic and continental settings. We welcome studies of the temporal and spatial evolution of mantle plumes in terms of composition, temperature, sources, magma chamber processes and surface expressions. We also encourage contributions addressing mantle metasomatism, the interaction between asthenospheric melts and lithospheric mantle and the tectonic processes triggering intraplate magmatism. We invite research that explores the geochemistry of bulk lavas (including isotopes), melt inclusions, single phases (including mineral-mineral and mineral-melt equilibria) or xenoliths from intraplate volcanic settings such as ocean islands, intracontinental basaltic fields and highly alkaline rocks.

Conveners: Nina Søager (University of Copenhagen), Valentin Troll (Uppsala University), Abi Barker (Uppsala University)

Session 1.2. Volcanism in the North Atlantic, from breakup to current time

The opening of the North Atlantic Ocean is a geological event that occurred over millions of years, during which the supercontinent Pangea broke up. As modern-day Europe (Eurasian plate) and North America (North American Plate) separated during the final breakup of Pangea in the early Cenozoic Era. This session will explore magmatic, tectonic and surface processes associated with the formation of the North Atlantic to our time.

Conveners: Armann Höskuldsson (University of Iceland, armh [at] hi [dot] is) and Thor Thordarson (University of Iceland, torvth [at] hi [dot] is)

Session 1.3. Understanding  Large Igneous Provinces and associated rapid environmental changes: from the North Atlantic Igneous Province and beyond.

Large Igneous Provinces (LIPs) are known to correlate in time with periods of mass extinctions and global warming in Earth history. This session aims at presenting new observations and results on; the formation of lips, on mass extinction intervals, and on the possible causal relationships between lips and associated environmental changes. This may include stratigraphic and proxy records of mass extinction, documentation of the petrology, chronology and geophysics of lips, petrogenetic processes, links to modern plume related volcanism, and modelling. Focus will be on the North Atlantic lip and how it may have triggered the Paleocene-Eocene thermal maximum (PETM). However, contributions on other lips and environmental crises, such as the end-Permian, the end-Triassic, and the end Cretaceous extinctions, are also welcome.

Conveners: Sverre Planke (CEED/VBPR, Oslo), Christian Tegner (Aarhus University), and Dougal Jerram (CEED Oslo/DougalEARTH, UK)

Session 1.4. Tephra markers in the circum North Atlantic area   

Tephra layers deposited in the arctic and north Atlantic area  during the Quaternary are widely regarded as having a huge potential for correlating and/or dating terrestrial and marine palaeoenvironmental archives such as ice, lake and marine sediment cores. This session will explore the use of tephra markers in circum north Atlantic area.

Convener: Prof. Ármann Höskuldsson (University of Iceland, armh [at] hi [dot] is) and Esther Ruth Guðmundsdóttir (University of Iceland, estherrg [at] hi [dot] is)

 Session 1.5. New trends in the study of the crystallisation and evolution of layered mafic complexes

For almost a century, layered mafic intrusions have been the natural laboratories for the study of fractionation of basaltic melts, providing the opportunity to test the results of liquidus experiments using idealized basaltic systems. For almost all this time, Wager’s immensely successful cumulus paradigm has been the basis for much petrogenetic modelling and has governed our understanding of melt evolution. Models developed for layered gabbros have proved successful for all naturally occurring magmatic systems.

However, increasingly detailed geochemical information and resolution in grain-scale imaging and analysis is challenging the dominance of the classic paradigm based on simple separation of solids and liquids in a well-mixed magma chamber. Alternative models, such as repeated replenishment and magma mixing, and the effects of liquid phase separation on the evolution of inwardly migrating solidification fronts, have profound importance for the modelling of lines of liquid descent, the relative timing of the arrival of new phases on the liquidus of the evolving melts, depletion/enrichment in trace elements, and mineralisation processes. We seek contributions that model magma evolution, explore the new ideas,  and evaluate and quantify the importance of in situ fractionation for the evolution of melts in magma chambers.

Conveners: Troels F. Nielsen (GEUS), Marian Holness (Cambridge University)

Session 1.6. Alkaline magmatism, carbonatites and associated mineral resources.                           

Alkaline igneous rocks and carbonatites are the world’s dominant resource for critical metals that are essential for modern technologies and renewable energy solutions. These include the Rare Earth Elements (REE), Zr, Nb, P, Ta, Li, U and Th. The Nordic region is a particular hotspot for exploration and research on such critical metal deposits. This session invites all contributions focussing on understanding the magmatic and hydrothermal evolution of alkaline igneous rocks, carbonatites and associated mineralisation, utilising new insights from petrology, mineralogy, geochemistry and geophysics. Contributions exploring magma chamber dynamics, roof zone processes, and physico-chemical parameters of melts and fluids which govern element transport and deposition are particularly encouraged. Contributions on ore characterization, (hydro-) metallurgy and mineral processing are also welcome. Jointly with Economic Geology and Mineralogy

Conveners: Anouk Borst (St.Andrews University), Adrian Finch (St.Andrews University).

Session 1.7. Magmatic Plumbing Systems.          

The origin, evolution and architecture of magmatic plumbing systems may be studied by a wealth of different methods, including petrology, geochemistry, geodetics, tectonics, analog modeling, seismology and structural mapping of exposed outcrops to name a few. This session aims at multi- and interdisciplinary studies gathering researchers from diverse fields of geosciences to exchange state-of-the-art observations, methodology and theory. Jointly with Metamorphic petrology, Tectonics and Structural geology, Geophysics.

Conveners: Rikke Pedersen, (NordVulk, University of Iceland), Steffi Burchardt, (University of Uppsala),  Olivier Galland, (University of Oslo), Christian Tegner, (Aarhus University).

Session 1.8. Building Baltica

Baltica is one of the major building blocks of the Proterozoic Earth, and the oldest part of present-day Europe.  In turn, it is made up by three parts, Fennoscandia, Sarmatia and Volgo-Uralia, that became united in the Paleoproterozoic. The main focus of this session will be on the evolution of the Fennoscandian shield, but we will also welcome contributions on the geology of the Ukrainian shield as well as the concealed basement of Poland, the Baltic republics, Belarus and Russia. We will also be willing to include contributions dealing with Caledonian geology, as well as Greenland geology.

Conveners: Åke Johansson (Swedish Museum of Natural History), Tod Waight (University of Copenhagen), Olav Eklund (Åbo Akademi University), Bernard Bingen (NGU)

Session 1.9. Micro-beam frontiers in magmatic, metamorphic, and hydrothermal systems

Crystals and glasses are rich archives of information on pre-eruptive magmatic processes and metamorphic histories and timescales. In particular, elemental and isotopic investigations of crystals and glasses (natural and experimentally-produced) provide clues to advance our understanding of magma sources and differentiation processes, metamorphic reactions under various P-T conditions, and volatile cycling from mantle and crust into the atmosphere. Micro-beam techniques are at the forefront of our capabilities to unlock the information recorded in crystals and glasses, and the methods are continually evolving to meet the new challenges in the geoscience community. This session aims to bring together researchers working with sub-crystal information from micro-beam techniques, such as EPMA, LA-ICP-MS, SIMS and micro-Raman to unravel the geochemical and geochronological history of crystals and glasses in magmatic, hydrothermal, and metamorphic systems. We particularly welcome contributions involving isotopic and volatile microanalysis of minerals and glasses as well as methodological studies and experimental approaches

Session 1.10. Geochemistry and modeling of Igneous Systems.

This session concerns the geochemistry of igneous rocks, especially the use of geochemistry in deciphering the chemical and physical evolution of melts all the way from the mantle to the surface of the Earth. Such processes include (but are not restricted to) partial melting, magma mixing, fractional crystallization, and assimilation. Geochemical evolution of melts is also crucial for the development of many economically important magmatic ore deposits.

Conveners: Karina Sand, Tod Waight (University of Copenhagen)

 

Session 2.1. Geodynamic and geological evolution of the Arctic

The Arctic region is a frontier of political, environmental and economic interests and challenges. Consequently, the Arctic geoscientific database is steadily growing requiring continuous reporting, discussion and updating of existing models. We propose a multidisciplinary session on the geodynamic and geological evolution of the Arctic region including the Arctic Ocean, the Arctic shelves and the surrounding orogenic belts. We welcome reports of all relevant work covering mantle dynamics, igneous and metamorphic processes, structure and formation of the lithosphere and sedimentary basins, its topographic evolution and plate-tectonic studies. The goal of this session is to develop a mutual understanding and, ideally, synthesis of cross-disciplinary geoscience studies in the Arctic region.

Conveners: Christian Schiffer (Durham University), Grace Shephard (University of Oslo), Arne Døssing (Technical University of Denmark), Christian Tegner (Aarhus University)

Session 2.2. Deformation and metamorphism of rocks: Microstructures, processes, and physical properties         

In the vast majority of metamorphic rocks, deformation and mineral reactions occur together. The interaction of reactions and deformation still are not well understood, although it is a key factor for understanding metamorphism and rheology. The interrelationship of the processes can probably be best studied using microstructures. We invite contributions from metamorphic petrology, structural geology, geophysics, mineralogy, and mineral physics relating to processes of reactions and deformation in rocks.

Conveners: Holger Stünitz (University of Tromsø), Thorsten Nagel (Aarhus University)

 

Session 3.1. Sedimentology posters

Conveners: Ida Fabricius

Session 3.2. Depositional basins

The session welcomes abstracts of studies of depositional basins - their structural and depositional development, their resources.

Conveners: Lars Henrik Nielsen (GEUS)

Session 3.3. Composition of siliciclastic rocks

This session welcomes contributions concerning mineralogical, petrographical and geochemical composition of siliciclastic rocks and how these can be applied to comprehend their provenance and diagenesis. The diagenetic changes of the siliciclastic rocks could benefit from comparison with porosity, permeability or other physical parameters. The provenance interpretation may be based on other parameters, such as geochronology.

Conveners: Rikke Weibel (GEUS) and Lars Henrik Nielsen (GEUS)

 

 

Session 4.1. Trans-Atlantic correlation of Proterozoic collisional belts and Paleoproterozoic Metallogeny of the Arctic

Convener: Jochen Kolb, (Karlsruhe Institute of Technology)

Session 4.2. Caledonian orogenic cycle: the Greenland-Svalbard-Scandinavia connection

Convener: Karolina Kośmińska (AGH University of Science and Technology, Kraków - Department of Mineralogy, Petrography and Geochemistry)

Session 4.3. Evolution of the North Atlantic margin: from Mesozoic rifting to Cenozoic inversion       

This session focus on the NW European margin, which has seen a long and complex evolution. Major extensional events, from the earliest Mesozoic failed rifting to the present separation of Scandinavia from Greenland have shaped a continental margin from the North Sea to the western Barents Shelf. Earlier extensional structures can be seen to influence later reactivation, with the most significant influence caused by major extensional detachments rooted in the Caledonian basement. We seek contributions covering case studies of structural geology and tectonics, spanning from Triassic extension to Cretaceous rifting and subsequent spreading.                          

Convener: Alvar Braathen, Department of Geosciences University of Oslo

Session 4.4. Vertical movements, changes in plate motion and mantle dynamics: observations and models in the north-east Atlantic domain

Unravelling the past and present vertical movements of the earth's crust is one of the most exciting topics in modern-day geoscience. A variety of cases exist which suggest that uplift is not related to classical mountain building or post-glacial rebound.  In Scandinavia, the debate has focused on the age and origin of the Norwegian mountains, but clearly, our understanding of vertical movements and onshore-offshore relations of the entire region are of importance for deciphering the underlying processes. We thus need to consider the history of uplift and erosion along the entire eastern margin along the NE Atlantic - reaching from Svalbard and the Barents Sea in the north to the North Sea Basin in the south – as well as the western margin, in East Greenland. Not to mention areas that are traditionally considered as stable cratons such as Sweden and Finland.  Recent studies provide for instance evidence of km-scale post-rift exhumation along margins in the region and of significant changes in the late Cenozoic spreading rates in the North-East Atlantic. These observations underline the need for new ideas and that may explain such changes and geodynamic models to verify them.  In this session we aim to provide a forum for the uplift debate. We welcome presentations about the burial and exhumation history of the Nordic and NE-Atlantic region, about neo-tectonic activity, about interpretation of the large-scale landscapes, about the timing and nature of weathering processes and about mechanisms that may explain the observations.

We invite contributions from the whole spectrum of mineralogical investigations and applications: New minerals, Mineral properties, Mineral composition of deep Earth and planets, Ore and economic minerals, Environmental science, Biominerals and more!

Conveners: Tonci Balic-Zunic (University of Copenhagen), Pekka Tuisku (University of Oulu)

Session 6.1. Paleozoic and Mesozoic stratigraphy, paleoceanography and paleoclimate                  

This session aims to showcase state-of-art advances in all aspects of Cambrian to Cretaceous paleoceanography, paleoclimatology and stratigraphy. Within this broad topic we intend to invite a range of contributions including, but not limited to, geochemistry, sedimentology, paleontology, and modelling, focusing on various sedimentary environments (whether continental or marine). Inter- or multidisciplinary studies are also encouraged.

Conveners: Sylvain Richoz (Lund University), Stéphane Bodin (Aarhus University), Nicolas Thibault (University of Copenhagen), Mikael Calner (Lund University)

Session 6.2. Open session in Palaeontology, palaeoecology and paleoenvironments

This session welcomes any aspect in the broad field of Palaeontology. It is an opportunity to present studies that do not fall within research covered by other sessions.

Conveners: Nicolas Thibault (University of Copenhagen), Sofie Lindström (GEUS)

Session 7.1. Climate from the Palaeogene to the Anthropocene - bridging timescales and approaches

This session focuses on paleoclimate and paleoenvironmental studies encompassed within the Cenozoic epoch. The aim is to gain understanding of modern change by evaluating past change - and likewise understanding the past by studying the present. We encourage submission of reports on climate, ocean, cryosphere and biosphere records on all time scales (from millions of years to the past decades) using geochemistry, sedimentology, palynology, micro- and macropaleontology, and modelling from both continental (including ice cores) and marine environments.

Conveners: Sofia Ribeiro (GEUS), Karen Dybkjær (GEUS), Nicolaj Krogh Larsen (Aarhus University), Marit-Solveig Seidenkrantz  (Aarhus University) and Camilla S. Andresen (GEUS)

 

Session 8.1. Ice and climate history in the Arctic and subarctic    

The Arctic’s climate, cryosphere and oceans are changing rapidly and influencing global climate systems. Understanding past warm conditions and past periods of climate change in the Arctic and subarctic will provide valuable knowledge about future high-latitude changes and associated global impacts. We invite proxy and/or model based submissions that address the magnitude, rates, causes and impacts of past climate changes in the Arctic and subarctic at all timescales from decades to millions of years. Submissions that compare recent observations with paleoclimate records or that link past Arctic climate events to global changes are also welcome.

Conveners: Kurt H. Kjær (Natural History Museum of Denmark, University of Copenhagen), Nicolaj K. Larsen (Aarhus University), Anders Schomacker (University of Tromsø)

Session 8.2. Glacial processes, deposits and landforms                     

During the Quaternary much of the Northern Hemisphere has been repeatedly affected by ice sheets that contributed to erosion in the highlands, deposition in the lowlands and shaping the Earth's surface over distances of thousands of kilometers. Although the spatial extent of glacial deposits and landforms is well established, the knowledge of specific processes that created them is often fragmentary. We invite contributions dealing with all aspects of the ice/bed interface covering glacial geology, sedimentology, geomorphology, and soil mechanics with emphasis on process interpretation. The topics may comprise but are not restricted to (1) the origin and properties of glacial tills and subglacial erosional and depositional landforms, and (2) interactions between glaciers and their beds including ice movement mechanisms, dynamics of fast ice flow, and subglacial hydrology. Studies of both modern and past glacial systems from all geographical regions are welcome. We encourage submissions that utilize innovative techniques to better understand subglacial environments involving field, laboratory, remote sensing and numerical approaches

Conveners: Jan A. Piotrowski (Aarhus University), Mark Johnson (University of Gothenburg), Per Möller (Lund University)

Session 8.3. Open session Quarternary geology

Conveners: TBD

Session 9.1. Circular economy

This session addresses raw materials in the context of circular economy. Moving towards a circular economy by conserving materials embodied in high-value products, and returning waste to the material streams as high quality secondary raw materials, can help reduce demand for primary raw materials, and help secure a sustainable supply of raw materials.

Conveners: Per Kalvig (MiMa,GEUS), Karen Hanghøj (EIT RawMaterials)

Session 9.2. Mineral resources and deep-sea mining in international and national seabed areas

This session invites contributors from different fields within natural sciences and technology to present and discuss relevant aspects related to the research, exploration and exploitation of deep-sea mineral resources, globally as well as more specifically in the deep-sea regions of the Arctic Ocean and North Atlantic. The aim is to shed light on the different geological, environmental and technological aspects and challenges that face the international community and the coastal States abutting such deep sea regions, in relation to potential mining of these resources.

Session 10.1. Geohazards in the Nordic and Arctic regions

The Nordic countries face varied spectra of geohazards, spanning from geophysical types such as volcano eruptions and earthquakes in Iceland over to quick clay landslides in Norway and Sweden, rockslides and related displacement waves in Norway and Iceland. In addition, are the Nordic countries exposed to extreme weather conditions, such as storms with high wind speeds, heavy rainfall and fast temperature changes that often result in landslides, flooding and coastal erosion. A special condition is that permafrost conditions vary from south to north strongly and special and are in the region more dominant than elsewhere in Europe. Thus there are special threats related to permafrost conditions or its disappearance due to climate change.

This session aims at presenting a wide range of geohazard studies in the arctic and subarctic regions, including case studies from various geographical, geological and topographical settings and more general evaluations of geohazards from a Nordic perspective and to discuss adaptation measures to those threats. The session is open for all types of geo and natural hazards present in the region.

Conveners: Þorsteinn Sæmundsson (University of Iceland), Reginald Hermanns (NTNU)

Session 11.1. Groundwater transport in cold, changing climates: theory, experiments, models   

In the context of a climate change, which hits particularly strongly Nordic climates, it is fundamental to understand the dynamics controlling the quality of groundwater resources. This quality is controlled by a variety of factors spanning from the natural interaction of circulating water with hosting rocks, the groundwater residence time, the mineral reactivity and geological nature of aquifers, as well as impact of external source of potential contamination. The session aims to bring together scientists studying different aspects related to groundwater transport, with particular emphasis on cold environments subjects to changing climate. The debated concepts span from new theories associated with transport in porous and fractured media to experimental analysis and mathematical modeling. The latter includes deterministic and stochastic approaches, effective modeling including Non-Fickian solutions and multidimensional model analysis. Multiscale approaches (from pore to aquifer scales) are addressed. The session addresses studies on vadose zone and saturated environments, and problems associated to single- or multiphase flow. The session debates approaches involving transport in variably-freezing conditions. The session targets both shallow and deep aquifers, and related main transport processes (advection-dispersion-diffusion-reactions). Contaminants can behave conservatively or as multicomponent reactive compounds, involving different experimental setups and model parameterization and approaches.

Convener: Daniele Pedretti, (Geological Survey of Finland, GTK)

Session 11.2. Groundwater – surface water interaction; chemical and quantitative impacts on rivers, lakes, wetlands, fjords and coastal areas.

The European Water Frame Directive (WFD) sets out objectives for the water environment. These include the protection of, enhancement and restoration of surface water, groundwater and groundwater dependent terrestrial ecosystems. We invite abstracts on knowledge share from international and national research projects and experiences obtained in national monitoring programs on the various parts of the hydrological cycle that are related to these issues.

Conveners: Jacob Kidmose, (GEUS), Bertel Nilsson, (GEUS)

Session 11.3. Integrated Hydrological Modeling

Integrated hydrological models represents an attempt to numerically simulate relevant physical (and in some cases geo-chemical) atmospheric-surface-subsurface flow processes at different scales ranging from the field plot scale, to the catchment scale, and even to the national scale. We invite contributions focusing on aspects of developing, testing, and applying integrated hydrological models covering aspects of for example; (1) climate change and hydrology, (2) rainfall-runoff, (3) groundwater-surface water interaction, (4) land use and nutrient discharge, (5) use of remotely-sensed data, and (6) calibration and model testing.

We encourage a wide range of submissions, including presentations of new methods and processing techniques, regional investigations, new datasets and data management, in particular related to the European Plate Observatory Project (EPOS), as well as topical reviews.

Conveners: Christian Schiffer (Durham U.), Valerie Maupin (U. of Oslo), Stéphane Rondenay (U. of Bergen), Sofie Gradmann (Geological Survey of Norway).

Session 13.1.  Geomicrobiology of the past and present        

Microbes are ubiquitous in nature and they have impacted geological processes since the dawn of life. The study of geomicrobial processes in modern settings is thus highly relevant as it gives us clues on ancient microbial ecosystems and their role and preservation in the geological record on Earth and potentially elsewhere; it provides a means to predict future global cycles; and it sparks potential new bio-based technologies to engineer our society in a more sustainable way. This session seeks microbiology studies on past, modern and potential future ecosystems, at all time and length scales, investigating their impact on geochemical and geological processes, the geological record, global cycles, our environment and society. Geomicrobial contributions can include, but are not limited to, topics such as the rise of atmospheric oxygen, metabolic pathways, bioremediation, soil stabilization, deep-sea and sediment biology, global geochemical cycles, electron transfer reactions and extreme biology/early Earth analogue systems.

Conveners: Karina K. Sand (Nano-Science Center, University of Copenhagen), Dominique Tobler (Nano-Science Center, University of Copenhagen, Emily Catherine Pope (Natural History Museum, University of Copenhagen)

Session 13.2. Bio-mineral interactions                          

This session focuses on the role organisms or organic compounds such as biofilms and natural organic matter have on mineral formation, transformation and properties. We welcome studies at all length scales e.g. focusing on how organic compounds affect crystallization, bio-mineral interface reactions, analyses of biomaterials (shells, bones, teeth) and biomineralisation processes. We hope that this session will attract research from different disciplines including field work, computational methods, wet chemistry and analytical techniques and stimulate critical and insightful scientific discussion, shearing of ideas and promote interdisciplinary collaborations.

Session 14.1. Geothermal energy and CO2 storage

Future demands and the role of the energy. By 2030 Europe could be generating more than 40% of its energy from renewables, using 38% less energy than in 2005 and emitting 50% less greenhouse gases than it did in 1990. Europe could be on track to deliver a 100% renewably powered energy system by 2050. Many of the green-energy and low-emission technologies exist today but need to be developed and expanded further. Besides cutting the vast majority of its emissions, Europe could also reduce its use of key resources like oil and gas, raw materials, land and water. Integrated use of the underground supports these future European targets. CO2 storage in the deep underground is important as part of the CCS technology, related not only to coal and gas fired power plants, but also on other major CO2 point sources like the chemical, petrochemical, paper, steel or cement industry plants and to bioenergy leading to scenarios with negative emissions. All these plants deliver products that we cannot do without even in 2050, but are also at the same time, highly energy- and CO2- intensive. Energy storage is a new and important challenge opening a new research domain which will play an increasingly important role in enabling the EU to develop a low-carbon electricity system. Increasing use of renewable energy sources (RES) for energy production (up to 20% to 2020 and much more in the following decades), largely coming from wind and solar power generation, and highly influenced by fluctuations in the weather, is causing a need for massive storage of electric energy. Electric energy storage technologies involving the use of underground offer large storage capacities and discharge rates. Integrated use of the underground. The underground offers both many resources and storage opportunities, and research is needed for development. Sharing tools and geological information on generic/common issues (e.g. 3D geological mapping, understanding hydro-thermo-chemical-mechanical and biochemical processes) will give synergies between various uses and can avoid conflicts in the utilization of the underground. Groundwater is the most important resource for people, agriculture and industry. At the same time it is the most vulnerable resource in the world, as it is influenced by climate change, agriculture, industrial and human activities. Management of the water resources is regulated by the Groundwater Directive and national regulations, and it is always necessary to consider groundwater first priority during integrated use of the underground. Possible influence of any underground activities on the groundwater should be estimated and modelled by research and avoided before any underground use. The groundwater monitoring and research should accompany all demonstration and industrial projects using underground. Detailed exploration of underground structures, properties of reservoir and sealing rocks, estimation of storage or geothermal reservoir capacity and 3D models of the studied underground space are needed to take decisions about the most economic use of the subsurface and multiple or integrated use of underground structures. A new concept of an integrated underground storage atlas should include storage options for all range of possible stored media, such as natural gas, CO2, energy or waste materials, and should include available infrastructure in connection to these media (natural gas pipelines, CO2 emission sources, renewable energy sources, electrical grids, abandoned mines, depleted oil fields, nuclear power plants, etc.). The underground can be used for several purposes at the same site, but the depth, technical and economic requirements for various uses are often different, but could also be overlapping. Preferred underground depth, temperature and pressure, water salinity, thickness of the reservoir and cap rocks, their porosity and permeability, internal and external structure of the storage site should be studied in details. In this case, the shallowest resources are potable water and shallow geothermal energy, followed by gas storage, CO2 storage and deep geothermal energy, which potential is increasing with depth, while rock mining can occupy any depth range. CO2 capture, utilization and storage (CCUS) give new advanced options for synergy between CCS, hydrocarbons, heat and geothermal energy production using the same underground space. CCUS could offer a low-cost stepping stone for fossil fuel independency. The use of underground for several purposes at the same time may cause conflict of priority, but they also could be applied in synergy. Potable water production has always priority to all other underground uses, therefore studies should compile detailed maps covering Europe assessing potential use and integrate planning of the use of underground.

Session 15.1. Tectonic, geodynamic, oceanographic, and cryospheric evolution of the Arctic Ocean from Mesozoic to present day

The decline in Arctic sea-ice in recent decades has turned the Arctic Ocean into the focus of international research on climate change. Located in the northern most part of the Earth, the evolution of the Arctic Ocean is a key factor for understanding global thermohaline circulation. However, despite its global implications, very little is known about the evolution of the Arctic Ocean during the Cenozoic and Mesozoic and its influence in global tectonic, oceanographic, cryospheric and climatic events. Significant unanswered questions regarding the tectonic opening and evolution of oceanic basins, influence of the formation of Arctic gateways in the oceanographic pattern and age constraints, structure and paleogeography of the Arctic remain highly debated in the research community. Within this interdisciplinary session we invite contributions that provide new insights of the Arctic Ocean evolution from tectonic, geodynamic, oceanographic, cryospheric or climatic points of view from its initial origin in the Mesozoic with the opening of the Canada Basin, to the Cenozoic when the Eurasia Basin opened, to the present. Multidisciplinary studies linking tectonic to surface and climatic processes are especially encouraged.

Conveners: Lara Perez (GEUS), John Hopper (GEUS), Christian Marcussen (GEUS), Yngve Kristoffersen (University of Bergen)

Session 15.2. Paleo‐landscape analysis based on high‐resolution marine data        

With this session, we invite contributions concerning submerged paleo‐landscape reconstructions based on high‐resolution marine data. We particularly encourage abstracts that utilize shallow marine reflection seismic data (subbottom profiler data, sparker, chirp, pinger and boomer data) but multidisciplinary studies that integrate other marine data such as sediment cores, multibeam bathymetry, side‐scan sonar, video and photographs, oceanographic and other archeological data are also most welcome. Reconstruction of the paleo‐landscape is a key discipline within Marine Geoscience studies and the understanding of landscape evolution is important when dealing with a wide range of subjects. These include climatic reconstructions, habitat mapping, raw material investigations, geohazards (i.e. subaerial and submarine slides), sediment traps, fluid flow across the marine‐land interface, and archeological investigations from the Paleolithic to the more recent past.

Conveners: Katrine Juul Andresen (Aarhus University), Matt Owen ( GEUS), Jørn Bo Jensen GEUS)

Session 15.3. The Quaternary geology of the North Sea Basin [co-organized with Quaternary Geology]   

This session will focus on the sediments and processes that have filled in the Quaternary North Sea Basin during the Quaternary.The Quaternary North Sea Basin extends from the Netherlands in the south to offshore Mid-Norway in the north (52-62°N), and has been studied by many scientists during the last 50 years. Relatively few studies, however, have looked into the large-scale development of the entire basin. There has been an increased interest for regional studies in recent years, but the results of these studies are not yet well known among the research community. We hope that this session will provide a forum for researchers to present recent insights into the North Sea Basin that will promote a better regional understanding. We invite contributions on the sedimentary evolution and processes of the North Sea Basin. Papers may address both glacial and non-glacial processes, for example fan developments, tunnel valleys or marine interglacial deposits using core proxy data, outcrops, and/or seismic or other geophysical data. Jointly with Quaternary Geology.

Session 16.1. Holocene coastal morpho-sedimentary systems: Archives, processes and forcing mechanisms         

Understanding of the Holocene evolution of coastal morpho-sedimentary systems is paramount for understanding the modern state, dynamics, and characteristics of present day coasts and to be able to forecast near future coastal evolution. Coastal geomorphic changes are driven by processes at play over a wide range of spatial (from global to local) and temporal (from millennia to event) scales. Sedimentary archives provide valuable insight into the patterns of change, adaptation or stability of coastal systems over time, observations which may in turn allow us to draw conclusions on the (forcing) parameters determining the long-term evolution of coasts. The aim of this session is to bring together researchers investigating into the Holocene evolution of coastal sedimentary systems such as barriers, beach-ridge systems, lagoons, near coastal lakes, etc. and/or the forcing mechanisms driving these developments such as sea level, wind- and wave-climate, sediment supply, inherited
topography. We invite contributions from coastal geomorphology, aeolian research, marine geology and all neighboring disciplines studying coastal sedimentary systems in Scandinavia and worldwide.

Session 16.2. Lidar in Geomorphology                 

Laser scanning or light detection and ranging (lidar) has revolutionized quantitative analyses of landscapes and landscape change. In several countries worldwide lidar is meanwhile a standard in research and development as well as in consulting, planning and management. However, laser technology is continuously developing, new processing methods and data analyses are developing and emerging, all leading to new possibilities of investigating and interpreting geomorphology. In this session we wish to bring together investigations from different environments and different disciplines, and to create a possibility for exchanging experience within this rapidly developing field of geomorphology. We welcome studies on developments in lidar technology, data processing, developments in methods and analyses, and interpretation of lidar data in any environment and across environments and disciplines.

Conveners: Zyad Al-Hamdani (GEUS) and Verner Brandbyge Ernstsen (University of Copenhagen)

Session 16.3. Remote Sensing - Digital mapping, remote sensing and 3d models in Earth Science

This session invites contributions from scientists working with remote sensing data (photogrammetry, laser scanning, spectral imaging, air-borne geophysical data etc.) and with the aim of bridging the gap between geological disciplines (structural geology, volcanology, petrology, sedimentology, stratigraphy, geomorphology, natural hazards etc.).  Rapid technological development is changing the way earth-data are collected across scales from ground to near surface (Unmanned Aerial Systems) observations and air- and space-borne platforms. Innovations and new developments in computer software offer new opportunities for data interpretation and visualization and provide novel ways of combining a wide variety of data sets collected with different purposes, at different scales and from various sensors and platforms. For this session, we seek submissions about the design and the evaluation of new and adapted concepts for the use of multi-sensor observation and monitoring methods. If you have been working with digital mapping or remote sensing techniques or you are interested in the combination of various data-sets and the technical aspects, this session allows you to present your case studies, explain the techniques and approaches used.

Conveners: Erik Vest Sørensen (GEUS), Sara Salehi (GEUS), Bjørn Henning Heincke (GEUS)

Session 16.5. Open session in Geomorphology

Convener: TBD

Session 17.1. Education, communication, preservation and Geoheritage 

Communication of the science in order to: 1) enlighten the decision makers 2) inform the public about geology 3) reach others? How geology is (best) handled in the primary and secondary school? Geology in international designations: world heritage sites (WHS), Geoparks, Biosphere Reserves, others - or in national designations and management of nature areas? Geology as a contributing factor to local development. About securing geodiversity.

Convener: Sandra Bollwerk (GeoMare) and Emma Rehnström, (Geologica Consult)
