Skrócony opis:

The lecture includes information about: 1) history and causes of global glaciations, 2) origin of glacier ice and glacier morphology, 3) glacial hydrology, 4) processes of glacial flow, erosion and deposition, glacial sediments, 5) development of various glacial landforms, 6) glacial and paraglacial hazards, 7) structure of permafrost, 8) periglacial climate, 9) freeze-thaw processes in active layer, 10) development of periglacial landforms and ground structures, 11) hazards arising from frost heave and thaw settlements, human impact, thermokarst, and engineering solutions.

The lecture refers to knowledge in fields of: glaciology, glacial and periglacial geomorphology and geology, geoecology, hydrology, climatology, spatial managing, and building engineering.

Pełny opis:

Following issues will be addressed during the lecture:

1) history and causes of global glaciations (brief history of continental glaciation, Little Ice Age, studies of ice-cores, Milankovitch cycles); 1h

2) origin of glacier ice and glacier morphology (accumulation and ablation zones, determination and reconstruction of ELA, elements of glacier morphology and types of glaciers); 1h

3) glacial hydrology (supra-, en- and subglacial drainage); 2h

4) processes of glacial flow, erosion and deposition, glacial sediments (glacial abrasion and plucking, deformation of glacial ice, lodgement-, melt-out- and deformation tills, “flow till”, glacitectonics, glacier-permafrost interactions); 4h

5) development of various glacial and glacifluvial landforms (striation, P-forms, roches moutonnees, glacial cirques and troughs, ground moraine, drumlins, flutes, Rogen moraines, de Geer moraines, terminal and lateral moraines, sandar, kames and kettles, eskers, glacial erratics); 6h

6) glacial and paraglacial hazards (surges, ice avalanches, glacier outbursts –jökulhlaups, landslides, quick sands) ; 1h

7) structure of permafrost, its regional history and distribution (depth of permafrost, taliks, thermal structure of permafrost; regional history of permafrost and distribution); 2h

8) periglacial climate (regional differences in periglacial climates); 1h

9) freeze-thaw processes in active layer (development of ground ice, frost heave, thaw settlement); 2h

10) development of periglacial landforms and ground structures (patterned ground, frost wedges and polygons, thufur, palsa, pingo, solifluction landforms, rock glaciers, thermokarst landforms); 6h

11) hazards arising from frost heave and thaw settlements, human impact, thermokarst, and engineering solutions (use of thermal piles, examples of infrastructure on permafrost (houses, roads, pipelines, airstrips); 4h.
