Models and Methods of Promoting Educational Services in the Internet Marketing

Web technologies and Internet marketing provide universities with new opportunities to organize more effective interactions with consumers of educational services. The educational portal of the university becomes a single point for the interaction of the university with all categories of interested persons. Modeling the structure of the educational portals, taking into account the behavior and preferences of consumers of educational services become especially relevant. The aim of the study is to analyze the processes related to the development and maintenance of the effective functioning of educational portals of higher education institutions, to model their structure, and to study the possibilities of using them to improve the quality ofpromotion of educational services

Special Issue: Recent advances (2008 – 2015) in the study of ground ice and cryostratigraphy

Cryostratigraphy involves the description, interpretation and correlation of ground-ice 17 structures (cryostructures) and their relationship to the host deposits. Recent advances in the 18 study of ground ice and cryostratigraphy concern permafrost aggradation and degradation, 19 massive-ice formation and evaluation of ground-ice content. Field studies have increased our 20 knowledge of cryostructures and massive ground ice in epigenetic and syngenetic permafrost. 21 Epigenetic permafrost deposits are relatively ice-poor and composed primarily of pore-filled 22 cryostructures, apart from an ice-enriched upper section and intermediate layer. Syngenetic 23 permafrost deposits are commonly identified from cryostructures indicative of an aggrading 24 permafrost table and are characterized by a high ice content, ice-rich cryofacies, and nested 25 wedge ice. Degradation of ice-rich permafrost can be marked by thaw unconformities, 26 truncated buried ice wedges, ice-wedge pseudomorphs, and organic-rich ‘forest beds’. 27 Studies of massive ground ice have focused on wedge ice, thermokarst-cave ice, intrusive ice, 28 and buried ice. Significant advances have been made in methods for differentiating between 29 tabular massive ice bodies of glacier and intrasedimental origin. Recent studies have utilized 30 palynology, isotope geochemistry and hydrochemistry, in addition to sedimentary and 31 cryostratigraphic analyses. The application of remote sensing techniques and laboratory 32 methods such as CT scanning has improved estimations of the ice content of frozen 33 sediments

CLIMATE AND ITS DYNAMICS IN THE PLEISTOCENE-HOLOCENE AS A BASIS FOR THE OCCURRENCE OF DIFFERENT RISKS UNDER THE DEVELOPMENT OF CRYOLITHOZONE

Abstract: Earth’s climate global changes are considered as the main conditions for the risk occurrence under the Arctic region development, where is cryolithozone. Study is conducted for the North of Russia. Main factors of climate change, causes of Cenozoic cooling, conditions for permafrost and glacier forming are considered. Climate oscillatory nature throughout the Earth’s history as the main climate property is analyzed. Cryolithozone development in the Pleistocene and Holocene, together with mainly negative cryogenic processes, follows climate variations. Current climatic epoch is a stage in this oscillatory course. Due to disagreements over the modern warming causes (natural course or anthropogenic influence), climate variations in the 20th century are studied. The reasons for the relationship between atmospheric temperature and CO2 concentration (modern warming main factor according to opinion of anthropogenic influence supporters) are considered. It is concluded that both long-period past fluctuations and short-period modern fluctuations are determined by natural factors caused by common sources of energy: solar radiation and heat flux from Earth’s interior. On the basis of the revealed patterns, ideas on future climate development trends are expressed, which must be taken into account when organizing long-term structures in cryolithozone. It is assumed that the Earth’s global climate will develop in the direction of prolonged cooling. Against this background, oscillations of different periods and different amplitudes will remain, the extremes of which will have ever lower temperatures. In the near future some warming can be expected as a continuation of the warming period that has replaced the Little Ice Age.</jats:p

FORMATION AND EVOLUTION OF THE RUSSIAN ARCTIC CRYOLITHOZONE (ON THE SHELF AND THE CONTINENT) IN THE PLEISTOCENE-HOLOCENE

The paper addresses age nonuniformity of the permafrost of the Russian Arctic shelf. It has been widely accepted that recent permafrost exists on the present-day shelf, which was formed under subaerial conditions during shelf draining in the Late Pleistocene, was flooded during the subsequent transgression, and now exists as a relic zone. However, there is also modern permafrost forming under submarine conditions. The paper considers the mechanism of its formation. The author suggests a mechanism that involves bottom soil freezing and ice formation due to constant natural transformations in seabed sediments. The proposed mechanism is supported by analyzes of certain sections of the bottom sediments of shelf and of the Pleistocene marine plains (ancient shelves) composed of dislocated sequences with massive ice beds. Analysis of the massive ground ice genesis identified different geological history as well as different transgressive and regressive regime of the Russian Arctic western and eastern sectors. The glacial cover has limited distribution in the Russian North and was absent on the Russian Arctic and Subarctic plains to the East of the Kanin Peninsula

Ground ice as indicator of the Pleistocene history of the Russian Arctic

Based on the analysis of massive ground ice origin, the geological development of the Russian Arctic in the Quaternary period has been considered. A classification of massive ice with two new genetic types (submarine and coastal-marine) and new mechanism of their formation have been proposed by the author. The possibility of permafrost formation with massive ice directly in marine environments has been calculated. Significant differences in the geological development of western and eastern Arctic, particularly in the transgressive-regressive mode, have been revealed. This calls into question the leading role of glacial eustatic processes in sea level fluctuations and brings to the fore the role of tectonic processes

Предложена классификация пластовых льдов, содержащая два новых, выявленных автором генетических типа льдов – субмаринный и прибрежно-морской, для которых даётся новый механизм их образования. Установлена возможность формирования вечной мерзлоты с пластовыми льдами непосредственно в морских условиях. Выявлены существенные различия в геологическом развитии, в частности в трансгрессивно-регрессивном режиме, между западным и восточным секторами Арктики. Это ставит под сомнение ведущую роль гляциоэвстатических процессов в колебаниях уровня моря и выводит на первый план роль тектонических процессов.
