White cabin, photo: Carolina Voigt.A long week of lab work is behind us. Our lab, known by the name of "white cabin", is quite small and under normal conditions would hardly qualify for the term "lab". But it is well equipped with everything we need for that part of the analyses we do here. We prepare the soil samples directly in the field for analyses that are done later on in our lab in Kuopio. Mainly this includes making soil extractions, which we freeze in Seida and then transport to Finland.

On Friday we were provided with a welcome distraction, when some people, who were driving a very huge tundra vehicle close to our cabin, got stuck in the wet fens in perfect view of our lab. In the picture you can see Sasha, Andrej and Misha, patiently waiting for the vehicle to be pulled out of the mud, hoping for a vehicle ride back to Seida (as it turned out, the vehicle's chains were broken and they had to walk). The whole act of rescuing and repairing the vehicle is still on-going and our usually quiet and secluded Tundra site is getting crowded with workers. Let's see what awaits us when we walk back to our field cabin tomorrow morning.

Walk to the village Seida, photo: Carolina Voigt, University of Eastern FinlandOne short comment about this walk to and from Seida, as we are not sure that we have mentioned it before: It is a 1.5 hour walk on tracks that are only driven by tundra vehicles and the last part leads through tundra without any real paths. This week it has been quite hot with almost 30 degrees every day – who would have thought that in order to experience a decent summer you have to travel to the Russian Arctic! and there is no shade along the way. As we couldn't use our transport vehicle (although it was ordered) at the beginning of the week, we had to carry a lot of the equipment needed for the next week's work, such as several liters of distilled water, food etc. With heavy backpacks, heat and mosquitoes, this walk was pretty tough. Luckily there were blueberries and cloudberries growing along the way, which kept us going.


Lab work, photo: Richard Lamprecht.Due to this, the writers of this post (Richard and Carolina) weren't too sad about spending some more relaxing hours in the lab, instead of heading directly to our main field site for measurements. Still, besides the lab work we are proud to announce that all measurements scheduled for this week took place as planned. A huge thanks goes to Igor, who kept the flux measurements going and only returned from his work with the weather station in the late evening, when masses of mosquitoes and small black flies made it impossible to use the computer (just imagine the amount of insects glued to the notebook's mousepad necessary to stop the cursor from working...).

And as the weeks in the field seem to be too short here we again decided to extend our working days until Sunday and only went back to Seida for Banya and one well deserved day of rest on Sunday evening. Tomorrow morning the Tundra is calling us back for another round of lab analyses as well as the usual measurements.

Green cabin tundra home, photo: Carolina Voigt, University of Eastern FinlandWith the last week's work finished, we managed to walk back to our house in Seida on Friday evening. So, for the first time in a couple of weeks, we enjoyed a well deserved and (almost) free two day weekend in the village.
The last week we started with some lab work in the white cabin and once that was done we continued with the usual CO2, CH4, N2O and accompanying measurements.

This week we faced some changes regarding our field team: Misha, Sasha and Andrej finished their work with us and left was our small group of just three people (Igor, Richard, Carolina) and we divided the work among the three of us and though we were just a small team we were working very effectively. Unfortunately, we also had to get by without our cook this week, so this made it all a bit tough, but we managed. Luckily our cook Zhenja returned yesterday and this weekend we were well fed again.

Especially measurement of the active layer depth is very hard work, at least in the mineral soils. And you can have a look at our drinking water! No, just kidding of course, this is lake water which we use for washing and sealing our gas chambers.

For the CH4 and N2O sampling we had a little bad luck with the weather this week. Due to heavy rain during the measurement we decided to re-measure the next day, as it was impossible to write during this, let alone read the notes afterwards (well prepared scientists that we are, we of course have rain-proof paper, but our field printer doesn't like to print on it). The next day we were met by some better weather conditions and were able to wrap up all our measurements by Friday evening.

We will walk back to the Tundra and our green cabin already this Sunday evening, in order to be able to start with our work right away tomorrow morning. Next week we will get some new team members as well as some visitors later in August, but more about this in our next posting.

Dinner, photo: University of Eastern Finland
Tomorrow it is six weeks to the day since we left Kuopio in Finland and travelled to the Russian Seida. July passed by very quickly and now in August we face some changes regarding our group. Today is Zhenja´s last days as our cook and our new cook, Natasha, has already arrived. A very lucky situation for us, because today we are blessed with two cooks, who are spoiling us with very tasty food as you can see on the picture. At the moment there is mushroom season here around Seida and we will surely have a lot of those this week.

Igor will also be gone for a couple of weeks before he returns at the end of August to help wrapping up the season here in the field. Our first "newcomer" in the field is Katharina, ecological microbiologist from the University of Bayreuth in Germany, who will do research on our peat circle and peat plateau plots and will stay until next week. In addition to that Dima, soil scientist from Syktyvkar in Russia, and some of his students will arrive at some point this week. We promise some new group pictures for our next post.


Cold night, photo: University of Eastern FinlandIt also seems like, for now, the best part of the summer is over and at the moment it is wet and quite cool. One of these nights we even had below zero temperatures and sleeping in the tent wasn't all too comfortable.


This week we will go a few days without any translator (Russian-English), but are confident that we can manage this. Communication between the non-Russian and the non-English speakers has improved a great deal, although now and then there remain some misunderstandings. So tonight for dinner we had salad with Brad Pitt – or was it red beet?
 



Ural mountains, photo: University of Eastern FinlandLast week we finally finished our lab work, yeah, and from now on we are able to fully concentrate on our field measurements. Our final lab work comprised the determination of microbial biomass in our soil samples via chloroform fumigation. All went well but we felt a bit sleepy afterwards. Might have been the chloroform, but more likely it was the lack of sleep.

One more point that is worth mentioning: These past few weeks, we (or more accurately: Igor) made some constant improvements to our lovely green cabin. So the large group of people we are going to be here in August will find a nicely isolated cabin, with beautiful new shelves, wall-paper in the "kitchen" and new "designer lamps". Something to look forward to!

New group picture, photo by Christina Biasi, University of Eastern Finland
After a few days without a working internet connection finally a new blog-posting! There is a lot going on in Seida and our Tundra site at the moment and our green cabin is crowded with people.

Today we are counting eleven people, which might not sound much but takes some getting used to after several weeks in a relatively small group. The main part of our newcomers are a group of scientists from Helsinki university, which are Minna, Tiina, Laura and Toni, who spent the day taking soil cores with a huge corer that made it possible to drill deep into the permafrost.

Toni and Laura are limnologists will sail across the thermokarst lakes in a small rubber boat.
As promised, you get the group picture today. Christina also arrived and will inspect the site and our work. Hopefully we pass this inspection.

The weather is horrible. Why don't we study tropical ecosystems? we keep thinking. Maybe we will suggest this for next year. Well, there are no moskitos anymore so let's look at the bright side.

LAI-measurement equipment, thoto by Richard Lamprecht, University of Eastern FinlandOtherwise, measurements are going fine, plants start to senescent and permafrost thawing depth is with 30-45 cm at its maximum. Attached is also a picture from the LAI (Leaf area index measurement device) from last week which was used to measure the density of the plant canopy. In addition to that we also do some point frame measurements to determine effects of warming on plant species composition.

More soon, if internet connection allows it.
