Between a rock and a hard place: A geosocial approach to water insecurity in Kabul (2024)
Journal Article
Hamidi, M. D., Haenssgen, M. J., Vasiljevic, M., Greenwell, H. C., & Stevenson, E. G. J. (2024). Between a rock and a hard place: A geosocial approach to water insecurity in Kabul. Water Security, 22, Article 100177. https://doi.org/10.1016/j.wasec.2024.100177

Approximately 50% of the global population currently experiences severe water scarcity, a situation likely to intensify due to climate change. At the same time, the poorest population segments bear the greatest burden of water insecurity. This inters...

Evidence for the formation of silicic lava by pyroclast sintering (2024)
Journal Article
Foster, A., Wadsworth, F. B., Tuffen, H., Unwin, H. E., & Humphreys, M. C. S. (2024). Evidence for the formation of silicic lava by pyroclast sintering. Nature Communications, 15(1), 5347. https://doi.org/10.1038/s41467-024-49601-6

Silicic lavas can be produced by the sintering of pyroclasts in the volcanic sub-surface, and then advected out of the vent. Here, we provide evidence for this mechanism preserved in the exposed post-glacial remnants of a silicic volcanic conduit at...

Aged carbon mineralisation from headwater peatland floodplains in the Peak District, UK (2024)
Journal Article
Alderson, D. M., Evans, M. G., Garnett, M. H., & Worrall, F. (2024). Aged carbon mineralisation from headwater peatland floodplains in the Peak District, UK. Geomorphology, 461, Article 109271. https://doi.org/10.1016/j.geomorph.2024.109271

Floodplains are dynamic ecosystems that cycle carbon, which is both delivered from upstream catchment sources and produced in-situ. These systems are being increasingly recognised as key environments of carbon processing, with the capacity for substa...

The Dynamics of CO 2 ‐Driven Granular Flows in Gullies on Mars (2024)
Journal Article
Roelofs, L., Conway, S. J., van Dam, B., van Eijk, A., Merrison, J. P., Iversen, J. J., …de Haas, T. (2024). The Dynamics of CO 2 ‐Driven Granular Flows in Gullies on Mars. Journal of Geophysical Research: Planets, 129(6), Article e2024JE008319. https://doi.org/10.1029/2024je008319

Martian gullies are landforms consisting of an erosional alcove, a channel, and a depositional apron. A significant proportion of Martian gullies at the mid‐latitudes is active today. The seasonal sublimation of CO2 ice has been suggested as a driver... Read More about The Dynamics of CO 2 ‐Driven Granular Flows in Gullies on Mars.

Globally significant mass of terrestrial organic carbon efficiently transported by canyon-flushing turbidity currents (2024)
Journal Article
Baker, M. L., Hage, S., Talling, P. J., Acikalin, S., Hilton, R. G., Haghipour, N., Ruffell, S. C., Pope, E. L., Jacinto, R. S., Clare, M. A., & Sahin, S. (2024). Globally significant mass of terrestrial organic carbon efficiently transported by canyon-flushing turbidity currents. Geology, 52(8), 631-636. https://doi.org/10.1130/g51976.1

Burial of organic carbon in marine sediments is a long-term sink of atmospheric CO2, and submarine turbidity currents are volumetrically the most important sediment transport process on Earth. Yet the processes, amounts, and efficiency of organic car... Read More about Globally significant mass of terrestrial organic carbon efficiently transported by canyon-flushing turbidity currents.

Microdroplets initiate organic-inorganic interactions and mass transfer in thermal hydrous geosystems (2024)
Journal Article
Yuan, G., Jin, Z., Cao, Y., Schulz, H.-M., Gluyas, J., Liu, K., …Wang, Y. (2024). Microdroplets initiate organic-inorganic interactions and mass transfer in thermal hydrous geosystems. Nature Communications, 15(1), Article 4960. https://doi.org/10.1038/s41467-024-49293-y

Organic-inorganic interactions regulate the dynamics of hydrocarbons, water, minerals, CO2, and H2 in thermal rocks, yet their initiation remains debated. To address this, we conducted isotope-tagged and in-situ visual thermal experiments. Isotope-ta...

A new interpretation of Pikaia reveals the origins of the chordate body plan. (2024)
Journal Article
Mussini, G., Smith, M. P., Vinther, J., Rahman, I. A., Murdock, D. J. E., Harper, D. A. T., & Dunn, F. S. (2024). A new interpretation of Pikaia reveals the origins of the chordate body plan. Current Biology, 34(13), 2980-2989. https://doi.org/10.1016/j.cub.2024.05.026

Our understanding of the evolutionary origin of Chordata, one of the most disparate and ecologically significant animal phyla, is hindered by a lack of unambiguous stem-group relatives. Problematic Cambrian fossils that have been considered as candid... Read More about A new interpretation of Pikaia reveals the origins of the chordate body plan..

Journal Article
Halford, D. T., Karolytė, R., Andreason, M. W., Cathey, B., Cathey, M., Dellenbach, J. T., …Ballentine, C. J. (2024). Probabilistic Determination of the Role of Faults and Intrusions in Helium‐Rich Gas Fields Formation. Geochemistry, Geophysics, Geosystems, 25(6), Article e2024GC011522. https://doi.org/10.1029/2024gc011522

Natural gas fields with economic helium (>0.3 He %) require the radioactive decay of crustal uranium (U) and thorium (Th) to generate He and tectonic/structural regimes favorable to releasing and concentrating He. An unknown is determining the role o... Read More about Probabilistic Determination of the Role of Faults and Intrusions in Helium‐Rich Gas Fields Formation.
