Yesterday we didn’t manage to sample, because of the storm!
Today was better but cloudy for TOMCAR sat.

June 9: Spring’s coming
First piece of green in Igarka,
Spring is definitely coming!
June 8: « Charnaïa Riechka »
Theo had the opportunity to join Anatoly and Sergeï on an excursion to the « charnaïa riechka » or « black river » which is named from its dark waters full of DOM!The river is a local contributor of the Ieniseï discharge, draining Taïga and wetlands and is currently at its high water level.
June 7: Ienisseï free of ice
May 22: Peak discharge
After a week waiting between ice break and ice-jam, looking at the ice’s movement, we eventually managed to sample by boat.
At the same time SPOT 5 was taking a picture of the river…A good thing to calibrate the new research project.
For the dissolved organic matter’s fluorescence we have almost the same value as the one we measured last year at the same period.
We have the feeling to be right at the peak discharge.
As if you were there
May 19: Impressive procession
At last, After two days of ice jam, ice started to move again by the end of the afternoon.
During 12h, we witnessed several millions of cubique meter of ice processing at the speed of 15km/h. It’s impressive.
Magical moment of observation of the Ienisseï’s strength getting closer to its flood’s peak.
May 16: Forced vacation
Yesterday, everything looked calm and quiet, but this morning, the Ienisseï has become a chaotic ice field.
It’s impressive how in few hours, we move from an equilibrium system to chaos.
All morning long, ice moved until a new ice-jam was formed and blocked everything, once again.
For us, it is forced vacation…until open water reappearance.
May 15: Everything seems calm
Second day of sampling in hovercraft.
Ice free spots are more and more important but patches of ice are still stable.
Ice is breaking and it won’t be long for it to move quickly, although tonight water level seems to be stabilized and everything looks very calm.
Today, the quantity of sediments is less important, but the color of the dissolved fraction is darker.
May 14: Ice is slowly breaking
We are getting better in managing spring flood sampling.
Indeed we already sampled with the hovercraft two days after the last sample with snowmobile (6 days last year) and we are confident in having high-resolution sampling of the spring flood peak.
Sacha (hovercraft pilot) did a great job in a typical white day (snow flurry and fog) to find a ice-free sampling spot (4 meters wide channel).
Harder filtration, Better color, Faster flow, Stronger water, Our Work Is Never Over.
