Phytoplankton blooms in the North Sea

This image, acquired by one of the Copernicus Sentinel-3 satellites on 25 June 2023, shows the intricate swirls from phytoplankton blooms in the North Sea. The blooms take on various shades, ranging from emerald green to turquoise, creating a visually captivating tableau against the deep blue of the surrounding water. 

Phytoplankton contribute to the cycle of marine nutrients, playing a key role in maintaining the overall balance and productivity of marine ecosystems. The existence and abundance of phytoplankton are not only crucial for marine life but also, as they produce oxygen and capture carbon, have far-reaching implications for the entire planet, emphasising the need to protect and sustain these invaluable organisms.

Monitoring phytoplankton is critical for understanding the effects of climate change on the oceans. Copernicus Sentinel-3 satellites provide data for monitoring changes in the marine environment.
