The first of may

Even if the Ieniseï seems quite calm on the surface (ice thickness:
1.5 m), things are stirring under the ice. We are starting to see
changes in the color of the water, as well as the DOM measurements.
Water is coming up further each time we drill into the ice,
demonstrating that the discharge from the river is starting to increase.
In the city, it was a bank holiday; flags were out, and there was
music, bbq and games for the children to celebrate the end of winter
and the arrival of spring. One of the festivities was the symbolic
burning of winter, and the representation of the arrival of spring
entered the festival on a snowmobile.
