Today we started our day with a lecture by ecologist Julia. She taught us about how carbon from the plant life and atmosphere were affecting the soil at different temperature levels.
We used a device called an Irga Gas Analyzer to check the carbon levels in different areas with different vegetation variations. Then the JSEP students split into teams to sample carbon levels of their own. Some groups sampled areas with shrubs and others without. First, we took our samples in a location close to town.
Then, we traveled to the edge of the icecap to compare the samples in two different climates. On our way to the icecap we saw this reindeer.
Also on our way to the icecap, we observed a noticeable difference in temperature throughout the different climates we traveled through. When we arrived, some of us caught sight of an arctic hare.
Then on our way home we saw a herd of musk ox! It was the cherry on top of a very fun and educational day.
