Produktbeschreibung

The Arctic and its surrounding marginal seas are considered some of the most sensitive elements of the global environment, which may respond rapidly to climate change. However, due to various reasons, our knowledge of the processes which drive the Arctic system today and in the past is still relatively sparse. Based on a multidisciplinary approach, German and Russian scientists describe in this book the natural paleorecords and modern data which were collected over the past 6 years. These marine and terrestrial datasets provide important new insights into the causes, impacts, and feedback mechanisms of this extreme Arctic environment.
