Seawater carbonate chemistry and dissolved organic matter dynamics during an oligotrophic ocean acidification experiment using large-scale mesocosms (KOSMOS 2014) ...
Dissolved organic matter (DOM) represents a major reservoir of carbon in the oceans. Environmental stressors such as ocean acidification (OA) potentially affect DOM production and degradation processes, e.g., phytoplankton exudation or microbial uptake and biotransformation of molecules. Resulting c...
