Question: Have you ever thought of becoming a marine biologists?

Christian Maerz answered on 14 Jun 2013:

Yes, in fact for quite a long time. But as we were living quite far away from the ocean, I did not really have access to the sea. But as life sometimes goes, I am now a marine geologist, and I am very interested in the activities of microorganisms in marine mud – so in the end, I guess I have come pretty close to being a marine biologist in the end 🙂
