The lecture content includes information about permafrost occurrence, structure and functioning; thermokarst processes; engineering problems and solutions used in permafrost regions; industrial expansion circum-polar regions; functioning of glaciers and glacial hazards (glacial surges, avalanches, outbursts); polar bases and scientific programmes; indigenous people of the Arctic, pollution of the Arctic.

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

Following issues will be addressed during the lecture:

- Permafrost: distribution and types, methods of determining its thickness, thermal profiles, active layer, frost heave and thaw settlement, thermokarst processes; 3h

- Engineering solutions used in construction of houses, roads, rail-roads, air strips, pipelines on permafrost – examples from Siberia, Tibet, Alaska, Canada, Spitsbergen; 4h

- Industrial expansion in circum-polar regions; 1h

- Mountain glaciers and ice-caps: distribution, changing mass balance, history of glaciations, contemporary rate of deglaciation, glaciological threats: surges, ice avalanches, glacier outbursts (jökulhlaups); 6h

- High-mountain infrastructure (touristic, communication, industry); 2h

- Arctic Ocean sea-ice: rate of ice melting, territorial disputes over access to mineral deposits, industrial expansion in the Arctic – chances and threats; 4h

- Contemporary polar bases and scientific programmes – examples from Spitsbergen, Greenland and the Antarctic; 4h

- Indigenous people of the Arctic, ethnic groups, life in the north, political organisations, struggle for land ownership; 2 h

- Pollution of the polar areas – reasons and effects; 4h

The outcomes of the subjects includes:

KNOWLEDGE OF

- permafrost: distribution and types, its structure and thermal pattern, thermokarst processes

- selected examples of infrastructure on in permafrost regions

- engineering problems (and mitigations) rising from freeze-thaw processes in the ground

- mountain glaciers structure and functioning

- glacial hazards (surges, ice avalanches, glacier outbursts)

- examples of high-mountain infrastructure (touristic, communication, industry)

- Arctic Ocean sea-ice issues (rate of ice melting, territorial disputes)

- examples of contemporary polar bases and scientific programmes

- settlement history and ethnography of the Arctic

- elementary knowledge of pollution issues

ABILITY TO

- locate permafrost regions on the map and assess permafrost thickness and character

- forecast permafrost reaction to climate warming

- foresee hazards to infrastructure resulting from freeze-thaw processes and assess methods of mitigation of construction failures

- foresee mountain glacial hazards

- find information about circum-polar regions

ATTITUDE

- to acknowledge specific conditions of managing cold regions (circum-polar and high-mountain)

- to acknowledge importance of climate warming for geographical environments of cold regions

Summative assessment in a form of an essay on one of the issues referred to during the lecture.

The grade from the essay constitutes 50% of the final grade, attendance - another 50%.

Unjustificed absence on 8 lectures results in failure of the subject.

The best grade (5) is given in case of high attendance (max 2 unjustified absences) and the essay which significantly broadens the lecture content.

It is possible to pass a re-sit session on the same terms.
