Journal Article
Pope, E. L., Cartigny, M. J., Clare, M. A., Talling, P. J., Lintern, D. G., Vellinga, A., …Vendettuoli, D. (2022). First source-to-sink monitoring shows dense head controls sediment flux and runout in turbidity currents. Science Advances, 8(20), Article eabj3220. https://doi.org/10.1126/sciadv.abj3220

Until recently, despite being one of the most important sediment transport phenomena on Earth, few direct measurements of turbidity currents existed. Consequently, their structure and evolution were poorly understood, particularly whether they are de...

For decades, scaled analog experiments have improved the understanding of a broad range of multiphase volcanological processes in controlled laboratory environments. Successfully modeled processes include magma flow through magma reservoirs, conduits... Read More about Analog experiments in volcanology: towards multimethod, upscaled, and integrated models.

Permeability heterogeneity of sandstone intrusion fluid‐escape systems, Panoche Hills, California: Implications for sedimentary basins globally (2022)
Journal Article
Callow, B., Falcon‐Suarez, I. H., Bull, J. M., Gernon, T. M., Ruffell, S., Grippa, A., & Hurst, A. (2022). Permeability heterogeneity of sandstone intrusion fluid‐escape systems, Panoche Hills, California: Implications for sedimentary basins globally. Sedimentology, 69(6), 2463-2485. https://doi.org/10.1111/sed.12997

Natural surface gas seeps provide a significant input of greenhouse gas emissions into the Earth’s atmosphere and hydrosphere. The gas flux is controlled by the properties of underlying fluid-escape conduits, which are present within sedimentary basi...
