Scientific drilling in the ocean and on continents provides unique window into the workings of the interior of our planet, Earth surface processes, paleoclimates, natural hazards and the distribution of subsurface microbial life. The past and current scientific drilling programs of the International Ocean Discovery Program (IODP), the International Ocean Drilling Programme (IODP3) and the International Continental Scientific Drilling Program (ICDP) continue to foster major advances in many interdisciplinary fields of socio-economic relevance, such as climate and ecosystem evolution, palaeoceanography, the deep biosphere, sustainable georesources, crustal and tectonic processes, geodynamics and geohazards. This session invites contributions that present and/or review recent scientific results from deep Earth sampling and monitoring through ocean and continental drilling projects. Furthermore, we encourage contributions outlining visions for future drilling projects, as well as new research emerging from scientific drilling legacy data.

Biogeomorphology provides an integrative perspective to study two-way interactions between organisms and landforms, linking ecological processes with erosion, transport, and deposition processes. This integrative lens shows how biotic–abiotic feedbacks shape Earth surface dynamics and landscape patterns across multiple spatial and temporal scales - from single plants to catchments and from events to millennia. Recent advances in biogeomorphic understanding have expanded applications across alpine, fluvial, coastal, and aeolian systems, for example in nature-based solutions. Key concepts such as biogeomorphic succession provide shared ground for cross-system comparison.

Despite a growing number of studies, biogeomorphology is still an emerging field with the conceptual and empirical foundation being under active development. In addition, transferring scientific knowledge of biogeomorphic feedbacks into management-relevant knowledge remains an ongoing challenge. With this session, we aim to advance the conceptual foundation of biogeomorphology and foster its transfer into practice. Contributions may range from alpine and polar environments over riverine landscapes to lowland and coastal systems, highlighting the relevance of biogeomorphology for improving process understanding and informing sustainable management strategies.

We invite contributions spanning fundamental process research, experimental, field-based and remote sensing studies, as well as applied approaches to environmental management and natural hazard mitigation. We particularly encourage work that uses biogeomorphology as a lens to address pressing geoscientific challenges, including ecosystem–landform feedbacks, human impacts on biogeomorphic systems, and the integration of multi-scale observations and models. Contributions from early career scientists are particularly welcome.

The atmosphere and cryosphere are closely linked and should be studied as an interdisciplinary subject. Most cryospheric regions have undergone significant changes in recent decades, as these areas are particularly fragile and less adaptable to global climate change. This AS-CR session invites both modeling- and observation-based studies on all aspects of the interactions between atmospheric processes and snow and ice, at local, regional, and global scales. Special emphasis is placed on the Arctic and Antarctic regions, high latitudes and altitudes, mountainous areas, sea ice, and permafrost regions.
In particular, we encourage studies that investigate the role of aerosols—such as black carbon, organic carbon, dust, volcanic ash, microplastics, pollen, sea salt, diatoms, bioaerosols, bacteria, and others—and their effects on the cryosphere, including snow/ice melt and albedo changes. The session also focuses on dust transport, aeolian deposition, and volcanic dust, with consideration of their health, environmental, and climate impacts in high-latitude, high-altitude, and cold polar regions. We welcome contributions from biological and ecological sciences, including studies on dust-organism interactions, cryoconites, bio-albedo, eco-physiological processes, biogeochemical cycles, and genomic analyses. Related topics include light-absorbing impurities, cold deserts, dust storms, long-range transport, glacier darkening, polar ecology, and more. Improved scientific understanding of atmosphere–cryosphere interactions is essential and should be better integrated into global climate prediction scenarios.
