  • This study identifies the rapidness of marine mineral reactions, directly after an extreme rainfall event. The reactions have the potential to affect marine cation and CO2 cycling, impacting element turnover on human time scales

  • The Si cycle is important to ocean productivity and nutrient cycling, however there are uncertainties in global budgets. Here the authors use a multi-isotope approach on seafloor sediments and pore fluids, finding that an unappreciated source of Si to the ocean is the degradation of seafloor serpentinites.

  • Calcite has a higher carbon dioxide uptake efficiency and lower cost than dunite, and it is a preferable material for enhanced benthic weathering as a carbon dioxide removal method, according to an analysis that combines laboratory incubation, benthocosm experiment, and numerical box model.

  • Carbon dioxide can be removed from the atmosphere at an uptake rate of 3.2 megatonnes of carbon dioxide per year by continually adding calcite to mud-bearing sediments in the Baltic Sea, according to an empirical model analysis.

  • Lagostina et al. show that relative abundances of Bacteria and Archaea in sediments of Guaymas Basin, Gulf of California, are controlled by temperature, while energy flux explains microbial community structure at the phylum-level and below. Hot diffusion-dominated and energy-depleted sediments are dominated by taxa with relatives in cold subseafloor sediments, while hot sediments with high energy supply from fluid seepage are dominated by taxa also found at hydrothermal vents and in hot springs.
