Sentinel-3’s Ocean and Land Colour Instrument will provide data for a variety of marine biogeochemical products including algal pigment concentration, total suspended matter, coloured dissolved organic matter and Chlorophyll-a, amongst others. Information such as this will, for example, help to improve the prediction of harmful algal blooms. In turn, this will help oceanic food sources to be managed more efficiently. The input of waste products into ocean and coastal waters can also be monitored so that the possibility of accidents and risks of major pollution incidents can be reduced.
