Carbonate weathering both consumes and releases carbon dioxide depending on timescale and hydrological conditions, complicating its representation in regional carbon budgets. Using paired high-frequency discharge and alkalinity measurements, we quantify the net carbon exchange of a temperate karst catchment. We identify a pronounced seasonal reversal in the direction of exchange, cautioning against the use of annual-mean approximations in regional carbon assessments.

Olivine-hosted melt inclusions preserve primary magmatic signatures that are otherwise lost during bulk-rock homogenisation. We analyse a suite of inclusions from a continental volcanic arc to derive revised partition coefficients for fluid…

Subsurface fluid injection can reactivate pre-existing faults and induce seismicity, posing a persistent challenge for subsurface energy operations. We couple geomechanical modelling with in-situ basin stress observations to evaluate fault-…

Probabilistic seismic hazard assessment in stable continental interiors is fundamentally constrained by short instrumental catalogues and recurrence intervals that span millennia. We develop a hierarchical Bayesian framework that jointly as…
