Geographical names, forms, and borders are not permanent. They are rather amorphous and change over time. Thus, reading a historical map not only requires to grasp the geo-spatial information, but also to detect the chronological information - in which time was the spatial description of a map valid? In this exercise, we will explore the chronological information contained in two different maps. You should only find their publication dates. They point at the possible period of validity of the maps.

We spoke with them about their research, their goals and the secrets of their success. More …. Biologist Marcel van der Heijden aims to increase agricultural yields — not just with artificial fertilizers, pesticides, and GM technology, but also fungi and other microorganisms. He's not afraid to resort to less conventional research methods, either. How will working from home be regulated in the future? How can a better balance be achieved between the demands of work and family life? We sat down with Martin Kleinmann, who heads up the commission, to learn more about how the Personnel Commission works.
The olive-branch dating of the Santorini eruption. Antiquity, 88 The date of the volcanic eruption of Santorini that caused extensive damage toMinoan Crete has been controversial since the s.
The geochronology group explores soil and landscape processes using relative and numerical techniques. We use a broad spectrum of methods to date landscape changes and geomorphic surface dynamics. Among these techniques are radiocarbon dating 14 C , 10 Be exposure dating, dendrochronology and others. A strong enhancement in methodology is achieved by cross-checking the different dating methods, by deriving time-dependent sequences and by the development of new techniques. The considered period is the Quaternary.
