May 28 : Wider, thiner, faster

Second sampling with the hovercraft today.
Cracks are multiplying and getting wider, ice surface has patchy brown colors and is getting thiner while the water level is rising faster and faster.
Ice blocks have started to climb on the river bank in some places and first compression crests are growing little by little here and there.

May 25 : Still on the ice but…

We are still sampling on the ice but yesterday the snowmobile and the trail were surfing!
In the sampling zone there is a thin layer of ice covering about 40 cm of melted snow on top of a thick ice layer of about 80 cm.
Seagull are arrived which is, according to locals, a sign that the ice break is coming.
Fishermen have brought back their cabines on the earth and are now fishing close to the river bank.
fDOM values are around the levels of the days just before the ice break of the previous years.
The water is now rising quite steadily (our landmark, a old stranded boat is disappearing).

May 12: Day off-overnight fishing !

We are sampling only every two days because we are running out of sampling bottles and are waiting for a precise date of delivery of the freight sent from France.
Sending freight is tricky in spring because the only way to do it is by plane and cargo is booked mainly for fresh food (fruits and vegetables).
Indeed the winter road closed 1 month ago and the first boat is expected by the end of may…


May 4 : Starting intensive sampling

After two days sampling in cloudy/snowy conditions, the sun was back for an ideal sampling time on the shinny ice of the Yenisey.
Current temperatures are quite cold about -3 to -6 °C during day and from -10 to -18 °C at night.
Thus ice is still thick (near 1m) and there are almost no sign of melting.
Fishermen in their cabines still have some great days of fishing to comme.
According to weather forecast, positive temperature should occur on friday, let see what happen next!
