Theory and methodology
- Konishchev V.N. Response of permafrost to the climate warming.
Response of cryolithozone to two different-scale climate warming episodes is discussed, namely of the recent decades of 20-21 centuries and of the Late Pleistocene-Holocene. Changes of particular features of permafrost under climate warming depend on the whole complex of landscape features and characteristics of its components which are also changing as a result of climate warming. Thus, within particular landscapes the permafrost degradation trend, i.e. higher temperatures in the permafrost layer and larger thaw zones (taliks), is accompanied by aggradation changes of permafrost parameters, i.e. lower or stable temperatures in the permafrost layer, thinner annually thawed layer, increased amount of ice in the upper layers of permafrost, etc.
Territorial structure of the world tourist market based on the social division of labor is discussed. Stages of general and specific labor division in the sphere of tourism have been identified. Spatial polarization of the world tourist market is described, as well as formation of modern central-peripheral structure of the global touristic space with its Centre, Semi-Periphery and Periphery and links between them. This model facilitates the analysis of tourism within the context of world development.
Methods of geographical studies
Basing on the available experience of mapping particular areas of the Astrakhan Biosphere Reserve and the near-mouth shore of the Volga River delta an algorithm of using diachronous space images with different spatial resolutions for monitoring of Hindu lotus distribution is suggested. The plant is an indicator of the ecological state of the territory and is put on the Red List of the Russian Federation.
The unprecedented steel production growth in the 2000s was characterized by the accelerated privatization, internationalization, financial recovery and spatial pattern changes in the world iron and steel industry. Under multinational private business it is maximum profit that becomes a key location principle, and the decision-making has shifted from the local level to macro-regional and global one. The iron and steel industry enjoys maximum profitability in India, Russia, Brazil and the Middle East where the majority of modern steel greenfield projects are concentrated.
The risk of sea coast abrasion has been evaluated and five categories of the risk have been identified according to the rate of coast transformation. Technique used for the compilation of the Abrasion Risk map at the scale of 1:2,500,000 is described. Summary of abrasion distribution and intensity for the sea coasts of Russia is presented.
Taldenkova E.E., Nikolayev S.D., Rekant P.V., Pogodina I.A., Portnov A.D. Pleistocene paleogeography of the Lomonosov Ridge (the Arctic Ocean)(basing on the study of sediment lithology and microfauna).
Ice-rafted debris (IRD) and fossil agglutinated foraminifers were studied in the sediments of the core sample ALR07-26C taken from 1359 m water depth in the southern part of the Lomonosov Ridge (the Arctic Ocean). The results were used for the tentative stratigraphic subdivision of the sequence and reconstruction of paleogeographic changes in the central part of the Arctic Ocean during the latest 200 thousand years.
Specific features of ice regime of the northern rivers of European Russia which are of decisive importance for the hydroecological safety of the territory, as well as their spatial and temporal variability were studied using the up-to-date hydrometeorological data. Trends of ice regime changes within the territory under study during recent decades have been revealed. Under low water situation autumn ice and slashed ice drift takes more time, ice jams become more often and the freeze-up period less protracted. More often thaws result in decreasing ice depth and snow storage within river basins. Winter break-ups are accompanied with ice jams and flooding. High water level during further freezing-up and the large amount of slashed ice within the river channel increase the risk of catastrophic ice jams during the break-up.
