1. 1. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :William Mörtsjö Zung; [2023]
   Nyckelord :;

   Sammanfattning : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

3. 2. Detection of slush on the Greenland Ice Sheet using Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Viktor Wu; [2020]
   Nyckelord :slush; Greenland Ice Sheet GrIS ; surface mass balance SMB ; sea level rise SLR ; satellite imagery; Earth and Environmental Sciences;

   Sammanfattning : Sea Level Rise (SLR) is a growing global concern that is heavily influenced by a warming climate. Because of a potentially large added mass to the ocean through ice melt, the Greenland Ice Sheet (GrIS) plays an important role in the contribution to SLR. LÄS MER

4. 3. Arctic Loess as an Environmental Archive : Identifying Weathering with XRF Analysis in West Greenland

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Isabelle Karnik; [2019]
   Nyckelord :loess; XRF; weathering index; Holocene climate; Greenland;

   Sammanfattning : Loess from west Greenland was studied to evaluate Holocene paleoclimate in the Arctic region. Deposits of loess are formed over long time scales through deposition of fine aeolian sediment and they exist in several places in the world. LÄS MER

5. 4. Applying GIS to Investigate the Spatial Variability of Sub-Glacial Hydrology under Land Terminating Ice Sheets in Western Greenland Ice Sheet.

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Welsh Samuel; [2016]
   Nyckelord :Hydraulic potential; Greenland; GIS; sub-glacial hydrological network; ice sheet dynamics; Hydraulisk potential; Grönländ; GIS; sub-glacial hydrologi; istäckesdynamik;

   Sammanfattning : With continued warming regional surface air temperatures around the Artic in recent decades, there is growing importance in understanding how ice sheet dynamics interact with a shifting global climate system. This research investigates the spatial variability of sub-glacial hydrology under land terminating ice sheets in Western GrIS, when applying varying overburden ice pressures within Shreve’s (1972) hydraulic potential equation.
