Introduction The purpose of the expedition LENA 2005 was to fill gaps of knowledge and to answer scientific questions that arose during former expeditions. Additionally, the monitoring program based at Samoylov Island was continued and expanded. Scientific investigations were focused on the following topics: A. Permafrost soils and ecosystems (• Chapter 3: Microbiological processes, trace gas fluxes and hydrobiology in permafrost ecosystems of the Lena Delta) B. Periglacial landscape dynamics (• Chapter 4: Studies of periglacial landscape dynamics and surface characteristics studies in the western Lena Delta) C. Ground ice as climate archive (• Chapter 5: Holocene ice wedges of the 1st Lena terrace) D. Modern delta hydrology (• Chapter 6: Report of the hydrological work in the Lena River Delta in August 2005)
