Our land mark is back!
Meaning, low flow stage is not far.

June 16: Igarka’s paradoxal charms!
Today we further discovered local watersheds.
We went sampling the Fox creek and Gravika river (samples for sediment’s transport and sonde’s measurements).
We went sampling the Fox creek and Gravika river (samples for sediment’s transport and sonde’s measurements).
These relatively small rivers are two Yeniseï tributaries with different regimes.
Fox creek has generally high level of suspended matter and turbidity whereas the Gravika has most of the time clear water.
The warm season is now well engaged with green landscapes and beautiful flowers but also awful clouds of mosquitos!

June 13: Look at the picture…
…Everything is green!
The water level is lowering rapidly.
We are still sampling 3 to 4 times a week.
Water is getting more and more clear and warm (12°C).
Still, too cold for a bath?
June 11: Because of the storm!
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
The Ieniseï is now totally free of ice and the last icebergs have been replaced by fisherman’s boats. The access to the field is easier since the branche has defrosted and enables us to sample on a daily basis the first stage of the flood recession. Windy days might be a harsh time when sampling on board of our small embarcation because of the waves it creates on the river.
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.
