Hei alle sammen, Justin again. Day 4 in Greenland started with us perfecting our process of cleaning out the sniffers before deployment. They need to be a clean as possible on the inside in order to not get any false readings from extracted gas, so we degreased and rinsed with boiling water.
With equipment in hand it was time to hike up the Teardrop lake. This lake was named for its shape on a satellite map, not for the tears we shed on the long hike up to it.
Once we got to the lake, Lisa began to look for a suitable site for drilling.
One advantage of our new sniffer design this year is the ability to go through a layer of soil over bedrock. Once we found a spot as such, the drilling began.
Because we kept losing rock cuttings in the soil, we decided that we had best just dig a pit down the the bedrock so we could see what we were dealing with and get some good samples. The pit was almost 2 feet deep!
When the day was done we were able to compare samples across the two different days. When you look at individual samples they don’t seem very interesting, but check this guy out:
