1. 1. Analysis of Rainfall-runoff processes at different scales in two mountainous, Arctic catchments in northern Sweden

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : June Johansson; [2023]
   Keywords : Arctic hydrology; Catchment response parameters; Water height recession analysis; Permafrost presence; Glacier presence;

   Abstract : The hydrological regime in Arctic catchments is being altered as an effect of climate change. To be able to project future changes in Arctic hydrology and hydrogeology, the mechanisms and drivers affecting runoff generation needs to be understood. READ MORE

3. 2. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

   University essay from Umeå universitet/Institutionen för fysik

   Author : Petter Ideström; [2023]
   Keywords : Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

   Abstract : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. READ MORE

4. 3. 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

5. 4. GIS, tracer test and water balance based hydrological analysis in Tarfala, Northern Sweden

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Elias Koivisto; [2022]
   Keywords : Tarfala; DEM; Tracer test; Water balance; the Arctic; Climate change; Permafrost; Glacier;

   Abstract : Current climate change poses a threat to the Arctic due to increasing temperatures, which cause the permafrost and glaciers to melt and thaw. This thesis focused on analyzing water balances in Tarfala catchment between 2000 and 2020 and using GIS as a support for tracer test results measured in Tarfala in 2021. READ MORE

6. 5. Vegetation cover change on Tindfjöll mountains, Iceland, assessed by aerial photographs, topography, and climate

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Guðrún Guðjónsdóttir; [2022]
   Keywords : Environmental changes; High Latitudes; Physical Geography; Ecosystem sciences; GIS; Climate Change; Vegetation change; Vegetation cover; Earth and Environmental Sciences;

   Abstract : Guðrún Guðjónsdóttir Climate change is having a great impact on the fragile High Latitude environment where warming is occurring at a rate at least double the global average. It is urgent to understand the relationship between climate and vegetation cover, which is playing an important role, as a carbon sink, for biodiversity, and for protecting against natural hazards.
