Picture: The photo shows a young female scientist and two young male scientists taking soil samples in a foggy winter forest. The woman is hitting the impact head of an earth drill stick with a polyamide hammer to drive it into the ground. One of the men is kneeling behind the drill stick, holding it with one hand by one of the two handles. The other man is kneeling next to it, holding another drill stick on his knees. Next to him is a white plastic bucket.
