Modeling of biogeochemical consequences of a CO2 leak in the water column with bottom anoxia

Introduction to the STEMM-CCS special issue

“…Migration of CO 2 within the sediments and the impact of the CO 2 release on the sediments is investigated using chemical, geophysical and hydromechanical methods (de Beer et al, 2021;Falcon-Suarez et al, 2021;Lichtschlag et al, 2021a;Robinson et al, 2021;Roche et al, 2021), electromagnetic techniques are applied to the investigation of fluid flow pathways in sediments (Gehrmann et al, 2021), while the feasibility of seismic techniques for detection and monitoring of a CO 2 leak is assessed (Waage et al, 2021). Modelling papers cover environmental monitoring and assessment including both detection, quantification, and impacts of a CO 2 leak in the water column (Blackford et al, 2020;Cazenave et al, 2021;Dewar et al, 2021;Omar et al, 2021;Yakushev et al, 2021), and migration in the sediments (Saleem et al, 2021). Finally, there is an assessment of the knowledge gained from STEMM-CCS and two other related projects (Dean et al, 2020) and a study of stakeholder views on North Sea CCS (Gonzalez et al, 2021).…”
