At the beginning of May I had possibility to work in snow. With 3 phd students we were making snow pits on two glaciers. It takes time… First you have to dig and on the upper part of the glacier is about 3m to dig.. Then you distinguish different layers of the pit. Different layers mean - different snow that is transformed with different weather conditions. So observing the snow you can understand what was happening during the year. You measure the temperature and density of each layer and then you take the samples for chemistry measurements- e.g. how much of the black carbon is each layer and biology- to see if something is living in such conditions. Interesting… but it takes tens of hours:) Therefore, we had different teams- the digging team, physics team and taking samples team. Last time I labeled the samples for chemistry and bio analysis.
