"Sentinel-3 will allow us to detect dangerous toxins from space."
Clarissa Anderson, Scripps Institution of Oceanography
'Harmful algal blooms are plaguing our oceans, especially the coastal zone where people harvest shellfish for human consumption. Sentinel-3a detects these algae by measuring the "colour" of the pigments they produce - similar to those in land plants. It also detects dangerous algal toxins near the coast, where it's important that we monitor ocean health. With these data we can better protect people and wildlife.'
