Space observation helps us to monitor water quality and protect biodiversity

Interview of Kerstin Stelzer, Physical geographer, Brockmann Consult, Hamburg, Germany

Season 1, episode 54

When using satellite data to assess water quality, the satellite-based instrument measures the light that is reflected from the water body. Within the water there are certain ingredients that influence the colour. We can detect algae blooms, which appear in green and observe their distribution. By combining these observations with in situ testing and models, we can provide users such as administrations, aquafarms and citizens with important information about the toxicity of these algae blooms and predict their growth and localisation.
