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

Volcanic ash alteration supports chemolithotrophic activity at the seabed and contributes to the production of microbial biomass during diagenesis, suggest analyses of isoprenoid and branched glycerol dialkyl glycerol tetraethers distributions in Mariana Trough tuffs and adjacent sediments.

Using data on oxygen variability taken from 32 representative reef sites, the authors show that hypoxia is already common. Under future scenarios of ocean warming and deoxygenation, the duration, intensity and severity of hypoxia will increase, with nearly one-third of reefs experiencing severe hypoxia.
