Experimental procedures for studying microbial reactions under high hydrogen gas saturations in microcosms Open
This methodology is proposed to investigate the response of microbial communities through analysis of headspace composition under high saturations of hydrogen. Changes in headspace composition will be related to specific communities and en…

Reliability of Contrast-Based Automated Fracture Detection from Decimeter Resolution Aerial Imagery Open
Aerial imagery that captures outcrop exposures of rocks enables the characterization of structural discontinuities such as faults and fractures across large and difficult-to-access areas. These datasets provide an opportunity to analyze th…

Low computational cost stochastic Gassmann fluid substitution modelling of hydrogen and carbon dioxide in clastic storage reservoirs Open
The ability to safely store non-hydrocarbon fluids in the subsurface, such as carbon dioxide or hydrogen, will likely be vital in all pathways to decarbonise global energy systems. Storage of these fluids will require monitoring programmes…

Capturing Geological Uncertainty in Salt Cavern Developments for Hydrogen Storage Open
Future energy systems with a greater share of renewable energy will require long-duration energy storage (LDES) to optimise the integration of renewable sources and hydrogen is one energy vector that could be utilised for this. Grid-scale …

Editorial: Earth Sciences and the Race to Net Zero Open
The race to net zero emissions, where greenhouse gas emissions match removals, is underway as part of the global response to the threat of climate change. To achieve net zero, change is required at pace and scale across all sectors of the …

A micromechanical investigation of diagenetically-induced changes to the anisotropic elastic properties of calcareous mudstones Open
Microscale diagenetic changes that occur during burial exert a profound influence on the elastic and mechanical properties of sediments—but are poorly quantified. The focus here is on how diagenesis influences the elastic properties of car…

Characterising the internal structural complexity of the Southern North Sea Zechstein Supergroup Evaporites Open
The internal structure and architecture of evaporite sequences is often overlooked, with attention frequently concentrating on the external geometries that salt bodies form. The availability of extensive 3D seismic data affords the opportu…
View article: Long-distance migration and venting of methane after marine hydrate dissociation
Long-distance migration and venting of methane after marine hydrate dissociation Open
Marine methane hydrate dissociation has been proposed as a mechanism for past global carbon cycle perturbations and could exacerbate climate change. Modulation of methane venting by bottom water temperature changes has been documented at t…

View article: Systematic spacing and topological variations in layer‐bound fault systems
Systematic spacing and topological variations in layer‐bound fault systems Open
Polygonal fault systems, sometimes termed layer‐bound faults, are extraordinary features of many fine‐grained sedimentary successions and have been described in a significant number of sedimentary basins over the last two decades. Their fo…

Climatically driven instability of marine methane hydrate along a canyon-incised continental margin Open
Establishing how past climate change affected the stability of marine methane hydrate is important for our understanding of the impact of a future warmer world. As oceans shallow toward continental margins, the base of the hydrate stabilit…

Assessing the feasibility of large-scale hydrogen storage in salt caverns on the UKCS using 3D seismic data Open
<p>The energy industry in the UK faces a challenge to decarbonize to support reaching net zero CO2 emissions by 2050. In nearly all scenarios emission reductions are characterized not only by energy demand reductions, but also the de…
