You observe that the surface of the sea water at an unusual color (red, brown, green ...)? This may be due to a proliferation of marine microalgae (also called efflorescence or phytoplankton blooms). Abundant foams or marine animal deaths can also be a sign.
This application allows you to report your observation in Brittany and Loire-Atlantique. So you quickly pass to a team of scientists a favorite of the phenomenon and its geographic location. The application also guides you to take a sample of this water colored sea (essential for scientists to identify microalgae).
After validation, your comment will be displayed on the map of the application and on the map Phenomer website (www.phenomer.org).
- The Phenomer program -
Conducted by Ifremer and its partners, Phenomer is a participatory science program, active in Brittany and Loire-Atlantique. It aims to better understand the blooms (blooms) of marine microalgae responsible for the phenomena of colored water: what species of marine microalgae are present in the colored water? What environmental conditions favor their growth? How biodiversity she evolves in time?
All the world's oceans are affected by blooms. Unpredictable and short term, these phenomena are difficult to study and poorly understood. They may reflect imbalances in oceanic ecosystems. Citizen participation greatly increases the chances of detecting them.
- When the sea is bloom! -
A phytoplankton bloom (or bloom) corresponds to a rapid proliferation, massive but fleeting microalgae. Some physical, meteorological, hydrological and environmental encourage their multiplication and concentration (for example, a prolonged period of high temperatures of air and water with no agitation of the water).
Marine Microalgae are microscopic algae in the oceans and essential to life on Earth. They play an essential ecological and economic role in coastal ecosystems. At the base of the oceanic food chain, they are the diet of many herbivores and filter feeders (such as shellfish), which in turn are eaten by carnivores (secondary consumers). This gives them a strong economic impact (shellfish farming, fishery). In addition, microalgae are the lungs of our planet. Thanks to their photosynthetic activity, they produce more than half of atmospheric oxygen.
