“…The main taxa on the map of engineering geocryological zoning of the Arctic coast correspond to the main genetic types of the coastal zone (abrasion, accumulative, and stable areas) according to the morphogenetic classification of Eurasian coasts developed within the scope of this project (Nikiforov et al 2004).…”

A set of digital maps including geology, Quaternary sediments, landscapes, engineering-geological, vegetation, geocryological and the series of regional sources have been selected to characterize the Russian Arctic coast. Based on this data, new maps of engineering geocryological zoning and zoning of the coast with respect to the intensity of exogenous geological processes and risk of technogenic impacts have been generated at the scales of 1:4,000,000-1:8,000,000. These maps are a tool to assess the impact of industry on the Arctic coast of the country.

“…However, its shallow southeastern part received much less attention. Studies of the Pechora Sea mainly described general oceanographic conditions in this region; most of them were based on 1-2 local field surveys (Loeng, 1991;Ilyin and Matishov, 1992;Adrov and Denisenko, 1996;Byshev et al, 2001;Nikiforov et al, 2005a;Nikiforov et al, 2005b;Mokhova et al, 2019). In particular, we are not aware of any study considering the Pechora plume as an individual water mass.…”

The Pechora River forms the large Pechora River plume in the southeastern part of the Barents Sea (also called the Pechora Sea). Many previous works addressed water masses in the Barents Sea, however, the Pechora plume received relatively little attention, therefore, many basic aspects of its structure and variability remain unknown. In this study, we focus on spreading of the Pechora plume in the Pechora Sea during ice-free periods. Based on the extensive in situ measurements and satellite observations, we describe the dependence of area and spatial characteristics of the Pechora plume on wind forcing, river discharge rate, and spring ice conditions. We reveal three general types of Pechora plume spreading, which are determined by the external forcing conditions. Joint analysis of a large set of in situ and satellite data provided opportunity to study the variability of the Pechora plume on the synoptic, seasonal, and interannual time scales. We reveal regular advection of the Pechora plume through the Kara Strait into the Kara Sea. In addition, we describe formation of a significant area of increased salinity within the Pechora plume formed during wind-induced coastal upwelling events. The results of this research are of key importance for understanding the physical, biological, and geochemical processes in the Pechora Sea and the adjacent areas of the Barents and Kara seas.

“…The landscape conception in the sense of climatic geomorphology seems to be a promising method to answer this question (Garner 1959(Garner , 1967Gutierrez 2005;Hoevermann 1985;King 1953;Nikiforov et al 2005;Pekala 1975Pekala , 1980Pekala andZietara 1977, 1980;Peltier 1950;Pope et al 1995;Stoddart 1969;Yang 2001). Geomorphologists postulate that climate must influence landforms and accordingly choose climatic boundaries which are anticipated to be significant for landforming processes (Gutierrez 2005;Hoevermann 1985;Pegui 1961;Peltier 1950;Wilson 1968;Yang 2001).…”

Natural environment of mid-latitude deserts of Central Asia is undergoing rapid changes. One of its elements is the relief. What needs to be particularly emphasized is its morphogenesis and landform evolution. In this study, a geomorphological research in the Ejina Basin (Inner Mongolia) is carried out with regard to identifying the main landforms and the contemporary geomorphic processes. We consider ancient and modern landforms as a unit and provide a general explanation for their evolution. Related environmental indications of existing landforms are discussed on the basis of climate geomorphology. Results show that the current basin is under the conditions favorable for the development and dominance of landforms originated from physical processes such as desiccationdeflation and aeolian. The landform system is characterized by its variable structure which is conditioned by specific hydrodynamics processes that existed during glaciations. It is suggested that landform patterns in Ejina are under the strong influence of rapid and/or intensive geomorphic processes. These signatures reflect the regional dynamics of landform evolution as characterized by a very effective integration of tectonic and climate-driven morphogenetic processes. Based on the present day climate data, we infer an obvious linkage of desert gorges and pediments in the basin to ancient humid phases, which provided high energy runoff for the formation of these landforms and were associated with erosional features under more humid and colder climate during the last glacial period. Desert plains and aeolian dunes in the central basin are the related products of contemporary climate. Clear evidences proving the landform inconsistency and landform instability in the Ejina are presented, indicating that the main geomorphic unit is experiencing transformation from alluvial plain to desert plain and then to aeolian dunes. However, the geomorphodiversity in the Ejina should be a compound result of complex surficial processes other than glaciation. Frost weathering, fluvial/alluvial action, desiccation-deflation and aeolian processes as well as climatic changes have played important roles.
