algal blooms


Satellite observation

• From oceanic to inland waters through coastal areas

• Daily to weekly survey

• Micro and macro algaes bloom

Algal blooms are observed at a worldwide scale, in coastal and inland waters. As it is often recurrent, this phenomenon has a direct negative impact on human and animal health, as well as on the biodiversity.

In order to anticipate the stranding of macroalgaes and the risk related to microalgaes bloom, we developed a dedicated service coupling near-real time surveillance and drift forecasts for blooms or rafts detected off-shore. In case a risk is detected, an alert is issued and notified directly to your smartphone to allow you taking fast and adequate decisions.
