Abstract

âº At pH8, urchins reduced sediment uptake of NOx and increased the release of silicate and phosphate. âº Reduced pH significantly affected the relationship between urchins and sediment nutrient fluxes. âº CCS leaks could alter nutrient cycling by disrupting key animal-microbial relationships.
