  1. 36. Changes in the Cold Surface Layer on a Polythermal Glacier during Substantial Ice Mass Loss

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Klara Blomdahl; [2015]
    Keywords : Polythermal glacier; digital elevation model; ground-penetrating radar; cold surface layer; Pårteglaciären; northern Sweden; Polytermal glaciär; digital höjdmodell; georadar; kallt ytskikt; Pårteglaciären; norra Sverige;

    Abstract : Climate change in the Arctic and sub-Arctic has induced substantial changes in the inland cryosphere. The warming climate is causing a reduction in glacier size and extent and the average net mass balance for Arctic glaciers have been negative over the past 40 years. READ MORE

  3. 37. External Conditions Effects on the Self-Organised Criticality of the Calving Glacier Front of Tunabreen, Svalbard

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Pontus Westrin; [2015]
    Keywords : Calving; calving model; self-organized criticality; glacier dynamics; Tunabreen; Kalvning; kalvningsmodell; self-organized criticality; glaciärdynamik; Tunabreen;

    Abstract : Mass balance processes in glaciers are important for determining the growth or retreat of ice. Calving, the mechanical breakage of ice bergs from a glacier front, is a poorly understood phenomenon. This process has great importance to the mass balance of many glaciers, for example on Antarctica and in the Arctic. A recent paper by Åström et al. READ MORE

  4. 38. Shipping in the World's Northernmost Ocean - Legal Disputes & Controversies in the Arctic Sea Routes & the Legal Impact of an Future Internationalization

    University essay from Lunds universitet/Juridiska institutionen

    Author : Daniel Jonsson; [2014]
    Keywords : Transpolar Sea Route; Northwest Passage; Northern Sea Route; Arctic; Article 234; Daniel Jonsson; Daniel Viktor Jonsson; Law and Political Science;

    Abstract : Arktis utgör ett av de minst utvecklade internationella regioner i världen. Trots politiska initiativ som arktiska rådet och liknande existerar det inte idag något övergripande legalt ramverk för att adressera flertalet juridiska dispyter och kontroverser. READ MORE

  5. 39. Atmospheric mercury deposition in alpine snow, northern British Columbia and southwestern Yukon, Canada

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Pia Karlsson; [2014]
    Keywords : ;

    Abstract : High mercury (Hg) levels have been measured in fish in Kusawa Lake (KL), a subalpine, partly glacier-fed lake situated in the southwestern Yukon, Canada, but it is presently unknown where this Hg comes from. One possible source may be atmospheric deposition of Hg in snow and subsequent release by melt into the lake. READ MORE

  6. 40. Miljögifter – ett hot mot isbjörnens överlevnad?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Jannike Ring; [2014]
    Keywords : isbjörn; miljögifter; klimatförändring; organokloriner; kvicksilver; PCB; DDT; PFC; polar bears; climate change; pollutans; organochlorines; mercury;

    Abstract : De rådande klimatförändringarna drabbar Arktis och dess isbjörnar hårt. Smältande isar frigör miljögifter som i årtionden lagrats upp och kan nu ta sig in i och biomagnificeras i den marina näringskedjan, där isbjörnen som toppredator utsätts för hög toxisk stress. READ MORE
