Our expedition in the Lena Delta came to an end the other week and we are back in Europe. Finally! Due to weather related complications in Tiksi it took us one week to get home and the waiting around airports was a bit tiring.
 
Saturday the 31st was our last day of fieldwork on Kurungnakh.
 
Thereafter, the boat transported the Scandinavian team back to Tiksi and the rest of us remained on Samoylov to do the last fieldwork and pack.
I was very pleased about the work done at Kurungnakh. Four soil stations were installed for measurement for validation of satellite data. Surface soil moisture and temperature is now being measured at different depths of the uppermost layers.

Accessibility is another criterion that needs to be considered, notably for the revisiting.
 
Furthermore, soil samples were brought home from each site. They will be used for soil specific calibration of the sensors that are installed at the stations.
 
For validation of another type of satellite derived data (TerraSAR-X), measurements were done during the days of satellite passes over a number of prepared grids.
 
The last week in field was also busy with exchanging help with colleges, such as reading data and reprogramming stations, collecting probes and more.
 
Thereafter, it was time to pack.

Much of the material and samples was to be sent back to Europe.
 
As sad as it was to leave Samoylov, it was nice to get a few days of rest in my old home town Uppsala, Sweden, before heading to the next fieldwork location.
 
In fact, I write this text while sitting in the bus 91 from Kiruna, which is the very last travel step to get to the research station in Abisko.
