1. 1. The implications of heavy fuel oil ban in arctic waters for sustainable arctic shipping

   University essay from Göteborgs universitet/Institutionen för marina vetenskaper

   Author : Kaung Thu; [2023-01-23]
   Keywords : Arctic region; heavy fuel oil; shipping; Sustainable;

   Abstract : The increased temperature in the polar regions is one of the significant impacts of global warming and consequential climate change. In the Arctic, regional warming leads to the accelerated loss of sea ice caps, which has opened up new international shipping routes. READ MORE

3. 2. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Author : Thibault Desjonquères; [2022]
   Keywords : Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

   Abstract : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. READ MORE

4. 3. Estimating active layer thickness at the high Arctic study site Zackenberg from remotely sensed ground subsidence

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Lotte Wendt; [2021]
   Keywords : active layer thickness; DInSAR; subsidence; permafrost; Zackenberg; CALM; Earth and Environmental Sciences;

   Abstract : The active layer thickness (ALT) is an indicator of permafrost thaw, which potentially leads to the release of large amounts of greenhouse gases under global warming, and thus could further amplify climate change. The thaw depth of the active layer also governs seasonal surface deformation, caused by the volume change between ice to water, which poses risks for slope stability and infrastructure foundations.

5. 4. Carbon Storage in Quaternary Deposits of the Circum-Arctic Permafrost Region

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Annegret Udke; [2021]
   Keywords : Quaternary deposits; Carbon storage; Permafrost region; Organic Geochemistry; Sedimentology; Vulnerability; Thermokarst;

   Abstract : Rapid warming in northern latitudes will lead to permafrost thaw and subsequent carbon remobilisa­tion and release to the atmosphere. To incorporate the permafrost carbon climate feedback in globalEarth System Models, it is of importance to know the carbon stored in the circum­Arctic permafrostregion as accurate and precise as possible.

6. 5. Combining luminescence dating and sedimentary analysis to derive the landscape dynamics of the Velická Valley in the High Tatra Mountains, Slovakia

   University essay from Lunds universitet/Geologiska institutionen

   Author : Roos van Wees; [2020]
   Keywords : IRSL; Chronology; Sedimentology; Landscape development; Middle Pleistocene; Modern Analogues; Clast shape analysis; Maximum particle size; High Tatras; Slovakia; Earth and Environmental Sciences;

   Abstract : Luminescence dating is widely used in combination with sedimentological analysis to reconstruct the landscape development of the Quaternary period. Here, quartz and K-feldspar measurements are used to date and evaluate the luminescence characteristics of sediments from seven sites of the lower part of the Velická valley (995-1250 m a.s.l.
