Wildfires are a global phenomenon responsible for tremendous environmental, social, and economic losses. Wildfires are also becoming a persistent threat. An increase in fire because of a warmer and drier climate demands novel tools for integrated post-fire land management and impact mitigation from the scientific community. Researchers, stakeholders, and decision-makers all over the world need to work together since wildfire impacts on soils and ecosystems also severely affects ecosystem services supplies, such as raw material and water provisioning, carbon storage, erosion and flood control, and habitat support, which are essential for human life. This session invites all who study the effects of wildfires on ecosystems, from wildfire prevention to post-fire mitigation by means of laboratory, field experiments, and/or numerical modeling.
In recent years the interaction between the ocean and the cryosphere in the Southern Ocean has become a major focus in climate research. Antarctic climate change has captured public attention, which has spawned many research questions. Recent advances in observational technology, data coverage, and modeling provide scientists with a better understanding of the mechanisms involving ice-ocean interactions in the far South. This session presents studies on physical and biogeochemical interactions between ice shelves, sea ice, and the ocean, including cross-disciplinary topics involving physical and biological oceanography, glaciology and biogeochemistry.
Scientists from around the world, along with private industry partners, are advancing exploration with a number of anticipated missions to the Moon, Mars, and other solar system bodies. Each mission has unique goals that call for strategically selected instruments to accommodate a diverse set of platforms, including rovers, orbiters, and human explorers. This session presents research on future planetary missions and instruments, including those in development, to share latest progress, discuss preflight scientific results, and increase awareness for potential cooperation.
With an increasing demand for low-carbon energy solutions, the need of geothermal resources is accelerating. Geothermal energy can be extracted from various, often complex, geological settings. Sustainable use of geothermal resources requires advanced understanding of the properties of the entire system during exploration as well as monitoring. This session features field, laboratory, and numerical experts who focus their research on geothermal sites to stimulate discussion in this multi-disciplinary applied research field.
Geoarchaeology studies can provide valuable opportunities to learn from the past, including human responses and adaptations to climate change, natural disasters, and changing ecosystems. Human activity is also a major player of global climatic and environmental change during the Anthropocene. This session seeks interdisciplinary papers and geoarchaeological case-studies that deploy various approaches and tools to help reconstruct former human-environmental interactions from the Palaeolithic period through modern times.
The vast majority of all telecommunications data (99%) transit through submarine and land-based fibre-optic cables. Global networks of cables encircle the Earth and cover the most remote regions of the continents and oceans. Fibre technologies are also becoming a standard tool for crustal exploration and seismic monitoring, along with natural hazard and urban activity monitoring. This session presents contributions that involve the application of fiber-optic cables or sensors in seismology, geodesy, geophysics, natural hazards, oceanography, urban environment, geothermal application, etc. with an emphasis on laboratory studies, large-scale field tests, and modelling.
In addition to the latest Earth, planetary, and space science research, vEGU21 is also featuring the contributions of four talented artists, who are sharing their artwork via social media (using the hashtag #EGUart). Kelly Stanford (@TheLabArtist) is a Manchester, UK-based science communicator and geography MSc student from the University of Hull’s Energy and Environment Institute who uses the visual arts to help scientists around the world communicate their work to the wider public. Her thesis is investigating how art and tabletop games can be used to enhance public understanding of flood risk, resilience, and climate-change topics. Kelly is creating a series of “Sci-portraits” (portraits that fuse the scientists with their research) of geoscientists participating in the meeting. She’s also helping to convene the hybrid research/art EOS session Exploring the Art-Science Interface, which aims to showcase research and art collaboration alongside one another.
Two significant flow hazard cascades have been captured with unprecedented detail, with events in Elliot Creek and Bute Inlet (Canada) and the Chamoli and Uttarakhand (India) both occurring recently. These events have a suite of background observations and baseline datasets on which to contextually place and explore these flows in a depth and breadth of detail that is unprecedented, potentially unlocking new understanding of hazard cascades from source to sink. We include papers that are observational, analytical or modelling based in their approach, across a variety of temporal and spatial scales.
Snow cover is continuously evolving over a wide range of scales due to meteorological conditions, such as precipitation, wind, and radiation. Most processes occurring within the snow cover are primarily controlled by the microstructure of snow (e.g., density, specific surface area). In turn, snow metamorphism changes the microstructure, leading to feedback loops that affect snow hydrology, weather forecasting, climate modelling, and avalanche hazard forecasting or remote sensing of snow. This session is devoted to modelling and measuring snow processes in sessional and perennial snowpacks across a variety of scales.
Many new high-resolution geophysical and geological data have been acquired in recent years to better clarify the temporal and spatial evolution of mountain building and subduction processes. In this session, we’ll discuss the existing geodynamic processes and state-of-the-art studies of the oceanic to continental subduction processes. The aim is to better understand the geodynamics of plate convergence, the role of oceanic crust, and the transition between subduction and collision.
Geoscience fields and time series show deterministic and stochastic fluctuations over a very large range of scales. This session focuses on methods, observations, and data analyses aiming to identify such scaling ranges and characterize them. We consider this scale and intermittency topic in the ocean, the atmosphere, the coupled atmosphere-ocean-climate system, in hydrology, and Earth sciences.
Constraining the past geomagnetic field variation is fundamental for several geoscience disciplines. Despite recent efforts to improve both spatial and temporal coverages of palaeomagnetic data, records and palaeointensity, data are biased toward the last 10 ka and the northern latitudes. More data are still needed from underrepresented geographical areas and temporal intervals. This session will feature methodological advances, new directional and palaeointensity data, especially respecting the FAIR data management, as well as new palaeomagnetic reconstructions at local or global scales to better understand the past behaviour of the Earth’s magnetic field.
Games have the power to ignite imaginations and place you in someone else’s shoes or situation, often forcing you into making decisions from perspectives other than your own. This makes them powerful tools for communication, outreach, and education, and as a method to train the public, practitioners, and decision makers. In this session, we showcase studies that have used games, gaming technology, and/or game-based approaches in research, teaching, or public engagement activities. The session is supported by the legendary Games4Geo Games Night.
Join us for an evening playing games and socialising! There will be games of all kinds, such as card, board, roleplay, and video, and each game will have at least some link to the geosciences! This will also be your chance to play the games showcased in the Games for Geoscience science session. You are also welcome to bring your own game to play and share.
