As you have learned from our previous posts, loess is a widespread terrestrial sediment, known to be an important archive for the changes of past environmental and climatic conditions. In order to use loess as a proxy, we first need to investigate the age of the sediments. In loess, different dating methods can be used, such as luminescence dating, radiocarbon dating, magnetic stratigraphy, and or ...[Read More]

The InterArctic project (Fig. 1) focuses on vulnerability, resilience and adaptation of northern societies facing global change. The current rapid warming of Arctic and Subarctic climates has already produced many changes in the social, economic and cultural behaviour of the populations inhabiting these regions and more changes are expected to come. In this context, looking at the past provides th ...[Read More]
