Driving through the snow in a ... Winter fieldwork part I

Our field season is over :(

Although the snowman see previous post melted several time new snow fell and made us not reach / remove the ISCO’s by car and prepare everything for wintertime. To speed up things we asked Werner from the Zwäcken hütte to help us with his snowmobile. From the movie you can see the result and why every professional hydrologist should have one ;) So a item on the Christmas wish list.

See movie yahoooooo:

Hey Mr. Snowman

After a day snowfall the raingauges throughout the catchement were full of snow. It covered the Isco's and sequential samplers. When the sun showed up the tipping buckets went crazy: click click click tip tip tip...

ho ho Merry - X-mas :S ??? First signs of winter...

Schneeflöckchen, Weißröckchen,
da kommst du geschneit;
Du kommst aus den Wolken,
dein Weg ist so weit.

Komm setz dich ans Fenster,
du lieblicher Stern;
malst Blumen und Blätter,
wir haben dich gern.

Schneeflöckchen, du deckst uns
die Blümelein zu,
dann schlafen sie sicher
in himmlischer Ruh'.

Schneeflöckchen, Weißröckchen,
komm zu uns ins Tal,
dann bau'n wir 'nen Schneemann
und werfen den Ball.

Snow flakes, white skirt,because you get snowed; You come from the clouds your way is so long.

Come sit by the window,O lovely star;paint flowers and leaves, we have you liked.Snow flakes, you shower us the flowers to then they sleep safely in heavenly peace.

Snow flakes, white skirt,Come to us Valley we bau'n 'nen Schneemann and throw the ball.



Yep the summer season is allmost over and it's time to prepare the stuff for the long winter sleep. Time to sit inside with a nice warm cup of coffee and cake and dreaming of the next fieldseason with the liquid part of precipitation. Here some pictures of the Alptal with the second snow cover which last more then one day.


First day and first time needed, snowcains on the car!

... "event sampling"


precipitated FeOH

You probably know this brown-reddish layers floating on top of pools and streams. Nope it’s not oil but FeOH ( iron hydroxide). A one week dry spell in the Alptal resulted in low flow condition of the system -> water levels in the streams where unusual low. In this low flow condition macrospores became visible see pic 1. by their reddish color, transporting small amounts of water with FeOH. The low discharge in the stream itself resulted in almost no turbulence. This calm flow made it possible for the FeOH to precipitate see pic. 2 and form a layer on the bottom waiting to be transported in the next high flow.

Autumn harvest time ...

After the rainfall from last weekend, now it’s harvesting time. The result is 276 bottles with total of 8.2 liters of water to be analyzed <:D in our Isolab.

20100925 Buckets of Rain ...

It started on Friday evening with a small shower and continued until Sunday morning. The widespectrum of precipitation: from rain, hail to snow. All Isco’s and Sequential samplers where collecting isotopes from rain and runoff, curious about the results.



This movie from the MeteoCH Precip-radar shows nicely the circling storm above the Alptal 


In the upper left corner time and date. In the center part you can see a mouse pointer indicating the alptal
