An impressive amount of sea foam has formed in recent days on the banks of the St. Lawrence River in the Lower River, following a combination of strong waves and the presence of many organisms such as microalgae and bacteria.
If the presence of foam at the river is normal for residents, it is still surprising to see so much, as in this photograph taken in Sainte-Luce, near Rimouski Monday.
The natural phenomenon occurs when it is selling and the waves are strong.
The organic matter in growth produces mucus and under the effect of the salt water and the mixing by the waves, that entails the formation of this famous foam.
“To give a concrete example, it’s a bit like putting egg whites into snow or lathering a beer. We create air bubbles and therefore a visible emulsion with organic matter, “summarizes Karine Lemarchand, director of the Program Committee in Oceanography at the University of Quebec in Rimouski.
Considering the strong winds, the waves and the amount of organic matter in the estuary at this time of year, the quantity observed is still normal at this time.
