abstract = {Two seismic field surveys were organized in the Fuglebekken coastal catchment of Hornsund, Spitsbergen, Svalbard, to map frozen and unfrozen ground and assess the spatial and temporal state of the permafrost. Surveys were conducted during maximum thawing in September and maximum freezing in April of the following year. The obtained seismic wavefields were interpreted using three methods: the dispersion of surface waves, seismic refraction, and travel time tomography. The seismic experiments were supported by nearby boreholes with continuous thermal monitoring. In the frozen survey, a gradual increase in ice content of water-filled sediments was found, farther from the coast. In September the shallow sensors in the boreholes validated positive ground temperatures down to 3.0 m depth, with below-zero temperatures at greater depths. However, seismic tomography indicated that the ground was unfrozen down to 30 m. The ground probably remained unfrozen due to intrusion of high-salinity seawater, even though it had been below 0°C. In April, in the area 300 m and farther from the coast, the ground below 3 m depth was frozen, except for a 19-m-deep open talik identified in a borehole at the slope of Fugle Mountain. We attribute the complex spatial extent, form, and condition of permafrost in the Fuglebekken coastal catchment to multiple factors, including variable solar energy, snow and ground cover, thermal and humidity properties of the soil, subsurface water flow, and seawater intrusion. The presented combination of seismic methods provides a new robust and precise approach to assess the spatial variability of permafrost in a coastal environment. The proposed interpretation shows deep percolation of subsurface flow into permafrost and its seasonal unfreezing at a depth of 30 m in both the zone of saltwater intrusion and the slope area. © 2022 John Wiley & Sons, Ltd.},

Two seismic field surveys were organized in the Fuglebekken coastal catchment of Hornsund, Spitsbergen, Svalbard, to map frozen and unfrozen ground and assess the spatial and temporal state of the permafrost. Surveys were conducted during maximum thawing in September and maximum freezing in April of the following year. The obtained seismic wavefields were interpreted using three methods: the dispersion of surface waves, seismic refraction, and travel time tomography. The seismic experiments were supported by nearby boreholes with continuous thermal monitoring. In the frozen survey, a gradual increase in ice content of water-filled sediments was found, farther from the coast. In September the shallow sensors in the boreholes validated positive ground temperatures down to 3.0 m depth, with below-zero temperatures at greater depths. However, seismic tomography indicated that the ground was unfrozen down to 30 m. The ground probably remained unfrozen due to intrusion of high-salinity seawater, even though it had been below 0°C. In April, in the area 300 m and farther from the coast, the ground below 3 m depth was frozen, except for a 19-m-deep open talik identified in a borehole at the slope of Fugle Mountain. We attribute the complex spatial extent, form, and condition of permafrost in the Fuglebekken coastal catchment to multiple factors, including variable solar energy, snow and ground cover, thermal and humidity properties of the soil, subsurface water flow, and seawater intrusion. The presented combination of seismic methods provides a new robust and precise approach to assess the spatial variability of permafrost in a coastal environment. The proposed interpretation shows deep percolation of subsurface flow into permafrost and its seasonal unfreezing at a depth of 30 m in both the zone of saltwater intrusion and the slope area. © 2022 John Wiley & Sons, Ltd.

Classical active layer can be thawed to a depth of approximately 2–8 cm, the thickest AL reaches over 20 m.

In glacial and sub-marine permafrost environments, the AL includes a layer of liquid water that seasonally accompanies the permafrost. Glaciers and ice sheets are usually devoid of the classical AL.

To provide a full picture of the occurrence of permafrost on the Earth surface, three different media must be considered: 1) exposed land, traditionally understood as “dry land”, 2) glaciers and ice sheets together with its bed and 3) the sea floor (continental shelves). The biggest weakness of the published study is not including glaciated areas in their estimations. The authors do not take either a clear position in this crucial matter, despite a radical divergence of opinions has emerged in recent years. Whether and in what way Greenland or other glaciated areas are covered by permafrost remains a pressing issue, as the final determination of the range of the permafrost worldwide depends on it. Until then, any criteria or benchmark used will continue to be ambiguous and open to discussion, maintaining the discrepancy at millions of square kilometers. © 2019 Elsevier B.V.

The area of each such land is determined by its borders. The question of the border between land and sea has everywhere raised certain doubts, but nowhere are these as severe as in the case of the Antarctic. Being entirely covered with ice creeping down to the ocean, Antarctica has a boundary that takes the form of an ice barrier along 95% of its length, with the ice in question entering the sea to a greater or lesser extent. There is thus no unified position as to where the borders of Antarctica should be taken to lie. Rather three different positions maintain that: 1. the border is the limit of the Antarctic ice sheet bedrock protruding above the water surface – and hence an entity particularly hard to determine given the aforementioned high level of coverage by a continental glacier; 2. the boundary of the Antarctic continent can be defi ned as a “grounding line”, i.e. a line where the creeping ice sheet as a whole rests on the sea-bed, and is thus in no part supported by water, i.e. floating. 3. the boundary of the continent is a land border together with the ice-barrier of glaciers ending in the sea, in particular ice shelves (the Antarctic continent is also sometimes taken to include so called “fast ice”; i.e. long-term sea ice frozen to the land or ice shelves and thus remaining at a standstill). Depending on criterion for the border that is adopted, Antarctica’s area can be seen to change markedly (in comparison with other continents). The size is usually calculated at between 13.5 and 14x106km2. However, this is not the end of the problems with defining borders and area in the case of Antarctica. As a continent may be deemed a continuous (in Latin continuus) land, hence the name of continent, it forms part of the lithosphere. However, ice joins other forms of water in being classified as part of the hydrosphere, and this precludes it being recognised as a component of the lithosphere. Antarctica is therefore believed commonly to be called a continent in a manner that has no regard to glaciation. In recent years, an image of the Antarctic bedrock called Bedmap 2 has been prepared on the basis of georadar research. This shows that 5.5x106 km2 of Antarctic bedrock, or 44.7% of the entire area, is located below sea level. This means that only about halfof the surface of the continent in the traditional sense can actually be recognized as land, or rather an archipelago similar to the one located in the Canadian Arctic.

Analysis was carried out in order to state whether in the High Tatras exist potential climatic conditions to preserve permafrost. Using freezing and thawing method it has been found that the High Tatras are in zone of potential occurrence of continuous, discontinuous and sporadic permafrost.

The movement of rock glaciers is their characteristic feature; creeping caused by plastic deformation, sliding down the material on the surface. The characteristic velocities are 5-160 cm/yr. The author also characterizes the rock glaciers occurring in Tatra Mts. In conclusion it was found, that the rock glaciers are less susceptible to the changes in climate, non-synchronous in evolution with classic glaciers and the active forms are most likely the indicators of existence of permafrost. However the rock glaciers may also be the indicators of palaeogeographic conditions connected with the decline of glaciation and occurrence of permafrost. -from English summary},
