Exact excerpt

We conducted a 39-day mesocosm experiment in spring 2023 in the German North Sea ... phytoplankton bloom and particulate organic matter dynamics are largely unaffected at low to moderate alkalinity additions of ~0-700 µmol kg−1 ... At alkalinity additions ≥~900 µmol kg−1, bloom development is delayed by ~6-9 days and particulate organic phosphorus is significantly reduced.
