Polar phytoplankton under multiple stressors - the effects of ocean acidification under varying environmental settings
In an era of dramatic anthropogenic perturbations of the global carbon cycle, the Arctic and Southern Oceans are experiencing rapid environmental changes, including ocean acidification, warming, sea-ice loss and changes in stratification. Given their important roles in ecosystems and biogeochemistry...
