Pictures from Churchill: Field workin it

Sphagnum.  This was the first time that we saw it in Churchill.

The last, forested site.  Kinda pretty minus the millions of mosquitoes
A Sphagnum core from the forested site.  You can see how it gets more and more densely packed and humified the further into the core you go.


The transect laid down for our main site
Glen and James working on coring through permafrost with the Russian Auger... This was seconds before it broke.
A core in the "Bog Beaver" or active layer corer.  You can see that the bottom of the core is lighter soil/sand.  There are shell fragments preserved in the bottom layer.  This means that there is a marine layer underlying the peat.  Before this area was a peatland it was under water. 
Peat close up.  Exciting eh?
Picture of the landscape around the peatland.
Oh yeah, exciting field shot.
The Bog Beaver at work.

The GPR!
So excited I got it to work!
Taking surface samples.  Measuring pH and depth to water table and cutting out the peat.
The lake near where we took surface samples.
The new and improved (and working) auger.
The working permafrost corer.  I got to work the drill, oh yeah.
Permafrost core.  You can see some solid ice in the bottom of it.
