Fieldwork 1 – My Friend of Misery

For those who know the Metallica song “My Friend of Misery”, here comes the transposition after one week and a half of fieldwork in the Alps.

The car

Fieldwork travels are usually quite exiting when somebody who is working in Antarctica, Greenland or Patagonia: famous airports, lost places, beautiful desolated landscapes… but if you are traveling from Aberystwyth, Wales to Vallouise, France, it ends up more like: rain all the way to Folkstones, 90 min delay with Eurotunnel The Shuttle (for half the price you are in France since 30 min), oil warning lit on in France as well as the windshield fluid. Of course, to conclude this 2 days trip, you need a NavSat system indicating a closed road and a detour through Italy and Frejus tunnel and its 43 euros fees.

So far so good, no? So let’s start with the really fun part: a couple of day of fieldwork going well followed by the loss of the car keys…

After a miraculous recovery by a British family after 5 days and the reception of the spare key from the university, I can tell the really story… you know, why I went through all this misery. Let me introduce you my friends (of misery, from the right to the left): Katie, Helena, Steffan and me.

Let’s talk science

If you exclude all these “minor” troubles, here is some of the science we succeed to do until now.

Concerning the streams exiting the Glacier Noir and Glacier Blanc (Ecrins National Park, France), we have currently two Discharge/Conductivity/Turbidity measurement stations (Steffan’s project) running on each of the stream. In addition, there is a fluorometer (Katie’s project), measuring some dye tracing experiment and as far as we can tell Glacier Noir has a well develop drainage system with a transit time of 30 min from the junction with its tributary.

Concerning the melting rate of Glacier Noir, we have 6 ablations stakes (Helena’s project) on the surface with 1-3 cm per day and a temperature station (thermistor in the air, on the top of the debris, in the middle and at the bottom) showing a nice delay in the “heat wave” transmission and an almost freezing ice surface.

For my part, I have a lot of terrain analysis to understand the dynamic and behavior of Glacier Noir, as well as debris thickness (and structure analysis) and GNSS measurements.

To end this post, I wish tell you how a field day can look like when you love your job:

  • Wake up at 4:00am
  • Start to hike up at 5:20 in the same time the rain starts
  • Setup a Discharge/Conductivity/Turbidity measurement station on the exiting stream of Glacier Blanc still in the rain since 2 hours
  • Watch a couple of seracs falling from the snout of the glacier not far away
  • Hope you put enough cable ties, tape, rope for your station to stand the non-stopping rain
  • Reach the car again by 10:30am after 5 hours in the rain and a temperature under 10°C.
  • Try to make all your equipment dry to do it again tomorrow…

And you know what? After a day like that, I still love my job… more than ever 😀
