More than two billion tonnes of human-produced carbon are entering the ocean as CO2 every year, over and above the natural amount. This extra CO2 is making seawater more acidic, with consequences for marine life that remain poorly understood.
Through cruises in NW European seas, to the Arctic Ocean and to the Southern Ocean – all areas of considerable natural variability in pH and seawater corrosiveness for CaCO3 shells – we will undertake join experimental /observational work, with focus on:
- in-situ biological and chemical observations across natural carbonate chemistry gradients.
- on deck carbon dioxide (CO2 ) perturbation incubations.
