(Final?) Day of field work - September 19, 2016

This past week, I finished what I hope is my final day in the field for my MSc thesis project. Our mission on Monday was to collect all our remaining sensors and data from the field, as well as auger a auger to a layer underneath the meadow that was imaged by the geophysics but difficult to interpret. The augering was messy and in the end not very successful; out target was at about 6 m below surface, but we did not get past 4 m deep. However, despite the slurry of mud that we got covered in, all the other data download went off without a hitch, and we were treated beautiful eye candy all day. There was a dusting of snow over the whole valley that morning, and the larch trees with their yellow, autumnal needles added a dazzling and vibrant element to the landscape. We may have looking like messy ogres by the end of the day, but we were treated to beautiful panoramas throughout.

A big thanks to Jen Hanlon and Polina Abrakhimova for helping me out in finishing off my field work!

For these coming weeks, I'm focussing on finalizing my inversion images and doing a proper depth conversion of my GPR data. Then the final interpretation on writing begins...

Happy to have a big truck to drive around this site

Some of my models of the subsurface based on 2015's resistivity and seimic refraction measurements. The black line shows the target of our digging.
This wet sloppy mess got all over us (but thankfully not on the camera.) With the sidewall collapsing and the suction on our auger so strong, we gave up after 4 m.

In some places, where there is water in the lakebed, it just disappears into small openings in the clay. 

Polina points out some other places where there are holes in the clay layer where water might be seeing in to. 

On June 28, the water was almost at the top of this stilling well. Where'd the lake go?

Quick Update - EAGE - NSG Barcelona 2016

As part of being named one of the "Best of SAGEEP 2016" presentations at the Environmental and Engineering Geophysics Society's March conference in Denver, I had the privilege of being invited to the conference of their European counterpart - the European Association of Geoscientists and Engineers (EAGE) Near Surface Geoscience (NSG) division. That involved a trip this September to Barcelona for the 22nd European Meeting of Environmental and Engineering Geophysics.

That's me, arriving at the conference centre on September 5

It was a pleasure to share my findings with a new audience and to make some new connections with counterparts in Europe. The presentation went smoothly, and I had some extra days to immerse myself in Catalonian culture and to enjoy Mediterranean heat.

My talk followed immediately after the opening ceremonies. It was a bit nerve-wracking to present to a large audience, but the presentation went smoothly. 
I had some extra time to do some sightseeing too. This was La Sagrada Familia cathedral, a famous Barcelona landmark
The trip capped off an enjoyable albeit hectic summer of field work, personal travels (including a wedding in Norway and family visits in Ontario), and of moving houses. I'm looking forward to settling back in to Calgary, completing data processing shortly, and beginning the process of writing my thesis.
