Short summary

We found that fluctuations in the marine environment during summer can trigger bloom formation in the nutrient-depleted eastern English Channel. Different storm impacts played various roles in promoting the growth of certain phytoplankton. Surplus nutrients supplied by rivers caused diatom blooms, while wind-driven storms supported the growth of pico- and nano-sized phytoplankton.
