Molecular ecological analysis of methanogenic communities in terrestrial and submarine permafrost deposits of Siberian Laptev Sea area
… stored under permafrost underground and undersea could be released into the atmosphere due to rising temperatures attributed to global climate change, little is known about the methanogenic microorganisms in permafrost sediments, their role in methane emissions, and their phylogeny. The aim of …

Characterisation and evolution of periglacial landscapes in Northern Siberia during the Late Quaternary : remote sensing and GIS studies
… in an extensive plain on the then subaerial Laptev Sea shelf. One important precondition for the Ice Complex sedimentation was, that the Laptev Sea shelf was not glaciated during the Late Pleistocene, resulting in a mostly continuous accumulation of permafrost sediments for at least this …

Carbon Dynamics in Northern Marginal Seas
The marginal seas have, despite their relatively small area, an important role in the global carboncycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. The carbon dynamic in two shelf areas – The Baltic …

Thermokarst and thermal erosion : degradation of Siberian ice-rich permafrost
… in the coastal lowlands adjacent to the Laptev Sea. This thesis investigates the spatial distribution and morphometric properties of these degradational features to reconstruct their evolutionary conditions during the Holocene and to deduce information on the potential impact of future …
