Investigation of variable aeration of monodisperse mixtures: implications for pyroclastic density currents (2018)
Journal Article
Smith, G. M., Williams, R., Rowley, P., & Parsons, D. R. (2018). Investigation of variable aeration of monodisperse mixtures: implications for pyroclastic density currents. Bulletin of volcanology, 80(8), Article 67. https://doi.org/10.1007/s00445-018-1241-1

The high mobility of dense pyroclastic density currents (PDCs) is commonly attributed to high gas pore pressures. However, the influence of spatial and temporal variations in pore pressure within PDCs has yet to be investigated. Theory suggests that...

Behaviour and fate of vanadium during the aerobic neutralisation of hyperalkaline slag leachate (2018)
Journal Article
Hobson, A. J., Stewart, D. I., Bray, A. W., Mortimer, R. J., Mayes, W. M., Riley, A. L., Rogerson, M., & Burke, I. T. (2018). Behaviour and fate of vanadium during the aerobic neutralisation of hyperalkaline slag leachate. Science of the Total Environment, 643, 1191-1199. https://doi.org/10.1016/j.scitotenv.2018.06.272

© 2018 Vanadium is a toxic metal present in alkaline leachates produced during the weathering of steel slags. Slag leaching can therefore have deleterious effects on local watercourses due to metal toxicity, the effects of the high pH (9–12.5) and ra...

A microbial role in the construction of Mono Lake carbonate chimneys? (2018)
Journal Article
Brasier, A., Wacey, D., Rogerson, M., Guagliardo, P., Saunders, M., Kellner, S., Mercedes-Martin, R., Prior, T., Taylor, C., Matthews, A., & Reijmer, J. (2018). A microbial role in the construction of Mono Lake carbonate chimneys?. Geobiology, 16(5), 540-555. https://doi.org/10.1111/gbi.12292

Lacustrine carbonate chimneys are striking, metre‐scale constructions. If these were bioinfluenced constructions, they could be priority targets in the search for early and extraterrestrial microbial life. However, there are questions over whether su...

Th/U and U series systematics of saprolite: importance for the oceanic 234U excess (2018)
Journal Article

The presence of excess 234U in seawater is a compelling argument for active delivery of solutes from the continents to the oceans. Previous studies found, however, that the complementary 234U deficit on the continents is surprisingly modest, which wo...
