T5. Arsenic and Other Geogenic Contaminants in Groundwater Resources: Linking Water Quality, Food Security, and Treatment
Prosun Bhattacharya, Abhijit Mukherjee, Saugata Datta, Mohammad Alauddin, Karen Johannesson, Jochen Bundschuh, Arslan Ahmad The fate, transport, and effects of arsenic and other metals in groundwater and other natural water systems from regional to local scales will be discussed. This encompasses occurrence, mobility, biogeochemical cycling, epidemiological, and sustainable mitigation.
T9. Groundwater Flow in Coastal and Marine Settings: From the Intertidal Zone to the Deep Seafloor
Alicia Wilson, Evan Solomon Huge volumes of groundwater lie beyond the boundaries of traditional watersheds. This session will explore groundwater flow and biogeochemical cycling seaward of the high tide line, including studies of submarine groundwater discharge and sub-seafloor flow.
T10. Groundwater Influenced Ecosystems: Springs, Gaining Streams, and Terrestrial Ecosystems
Brad David Wolaver, Laura J. Crossey, Rebecca Matthews Frus, Steven P. Loheide II Groundwater maintains aquatic and terrestrial ecosystems in varied climates and seasons globally. Multidisciplinary advances in field and modeling techniques are needed to improve how such systems are characterized, monitored, and scientific findings conveyed to decision makers.
T17. Polar and Alpine Changes
W. Berry Lyons Polar and high alpine environments are undergoing rapid changes including cryosphere loss, with important geomorphological, hydrological, biogeochemical, and ecological consequences. This interdisciplinary session will explore these changes in both the Arctic and Antarctic.
T19. Springs: Providing Insights on Critical Groundwater Quality and Quantity Issues
Brian Katz, Sue Swanson, James L. Berglund This session will highlight research studies on springs that cover a range of topics, including water quality, geochemical and microbiological tracers for elucidating sources of anthropogenic impacts, water quantity, ecology, springs restoration, and climate change.
T20. The Critical Zone As Heterogeneous Media: Implications for Physical, Chemical, and Biological Processes
Wendy M. Robertson, Nicole West, Zsuzsanna Balogh-Brunstad, Michael H. Young We encourage contributions that characterize heterogeneities in the Critical Zone and their connections to hydrologic and biogeochemical processes at a range of spatial and temporal scales.
T58. Oxygen and Ecosystems from the Proterozoic to the Paleozoic
Noah J. Planavsky, Devon B. Cole, Christopher T. Reinhard This session will explore recent efforts to develop a more comprehensive understanding of coupled oxygen availability and environmental conditions with biotic evolution and ecosystem development from the Proterozoic to the early Paleozoic.
T59. Studies in Paleobiology and Paleoecology: In Honor of Professor David J. Bottjer
Thomas J. Algeo, Pedro J. Marenco, Margaret L. Fraiser, Matthew E. Clapham This session honors Professor David Bottjer on the occasion of his stepping down as Editor-in-Chief of Palaeogeography Palaeoclimatology Palaeoecology after 16 years. He is a paleobiologist and paleoecologist working on organism-sediment interactions, early metazoan life, and recovery from mass extinctions.
T60. The Onset of the Great Ordovician Biodiversity Event (GOBE): Testing Hypotheses with Diverse Data Sets
Rebecca L. Freeman, Alycia L. Stigall We request contributions testing hypotheses concerning the Late Cambrian to Ordovician biotic and abiotic drivers of GOBE. Diverse data sets illuminate the timing, initiating conditions, stratigraphy, and paleontology of this significant event in Earth’s history.
Ross P. Anderson, Lidya G. Tarhan, Sean McMahon Exceptionally preserved soft-tissue fossils are essential to the reconstruction of the emergence and diversification of early complex life. Here we consider new geologically and experimentally derived insights into the taphonomy of Proterozoic–early Paleozoic Lagerstätten.
T67. Fossils and Fossilization in Amber
Victoria E. McCoy, Sarah E. Gabbott This session will explore all the diverse areas of amber paleontology, from the description of exceptional specimens, to the investigation of amber taphonomy, to innovative approaches to image or chemically characterized fossils in amber.
T68. Proxy Approaches to Determine Forest Structure in Deep Time: What Have We Learned?
Richard S. Barclay, Regan E. Dunn, Heather V. Graham We will gather a diverse set of scientists who apply cross-disciplinary approaches to fossil plants and animals, stable isotopes, biogeochemistry, and the sedimentary record to assess the structure and density of forests in deep-time.
T69. The Role of Silica in the Earth System: From Organisms to Global Biogeochemical Cycles
Jonathan P. Wilson, Caroline A.E. Strömberg, Patrick J. Frings This session seeks to bring together geochemists, modelers, soil scientists, physiologists, and paleontologists to discuss state-of-the-art knowledge of the terrestrial and oceanic silica cycles, links between them, and connections with other biogeochemical cycles through time.
T70. Paleogenomics and Geobiology
Jeffrey R. Thompson, David J. Bottjer This session will include, though is not limited to, presentations utilizing approaches to interpret the fossil record and evolutionary trends through integration of data from the rock record with molecular biology, genomics, and developmental biology.
T94. Limnogeology—Progress, Challenges, and Opportunities on Earth and Beyond: A Tribute to Beth Gierlowski-Kordesch
David B. Finkelstein, Lisa E. Park Boush This session explores new insights, critical thinking, and integrated analytical approaches, including sedimentology and stratigraphy, remote sensing, geophysical techniques, geomicrobiology, and geochemical studies applied to the interpretation of modern and ancient lake environments and sediments.
T143. Curating Physical Samples in a Digital World
Leslie Hsu, Megan Carter, Anders J. Noren, Lesley A.I. Wyborn Physical samples, such as cores, fossils, and water, have unique challenges for data stewardship because they are difficult, if not impossible, to fully digitize. We will explore challenges and solutions for digitally curating physical samples.
T170. Rock Transforming to Soil—The Weathering Engine Intersects with the Carbon Cycle
Zsuzsanna Balogh-Brunstad, Marjorie Schulz Geology and biology interact in hotspots of geochemical activity along the root rhizosphere. these reactions control soil development, nutrient availability, erosion, carbon cycling, etc. We welcome submissions from all scales, laboratory, field, and modeling studies.
T248. Microbialite Textures and Chemical Signatures in Continental Settings: Forging the Link between the Modern and Ancient
Thomas A. Hickson, Julie K. Bartley We seek abstracts that focus on the textures (macro- and microscopic) and geochemical signatures of microbial activity in continental settings. These abstracts should clearly forge a strong link between ancient rock sequences and modern biogeochemical processes.
T249. New Voices in Geobiology
Victoria A. Petryshyn, Marc Laflamme, Lydia S. Tackett, Rowan C. Martindale, Simon A.F. Darroch, Carie M. Frantz The goal of this session is to bring together new research focusing on the interplay between geologic and biologic processes with a special emphasis on new field sites, novel materials/methods, and the development/refinement of proxies.
T250. Perspectives on The Deep Biosphere: Twenty-Five Years of Geobiology
John R. Spear, Blake W. Stamps A critical yet little understood compartment of Earth is the life that lies beneath, the deep biosphere. Rich in geological, geochemical, and biological complexity, the subsurface continually supplies ecosystem services that maintains life on the surface.
T254. The Co-Evolution of Life and Its Environment during the Precambrian: The “Boring Billion” and Mid-Proterozoic Emergence of Complex Life
Roger Buick, Matthew Koehler, Charles Diamond This session explores the middle chapter of Earth’s history, which was characterized by an apparently prolonged period of biogeochemical stasis. Contributions that consider Proterozoic redox conditions, early eukaryotic evolution, long-term climatic regulation, and biogeochemical cycling are encouraged.

Michael Kipp, J. Alex Zumberge, Timothy W. Lyons This session explores the dynamic transitions of the Neoproterozoic, and particularly welcomes contributions that assess marine redox heterogeneity, cause-effect relationships between tectonic, climatic and biological evolution, and the chronology of these critical events.
