1. 1. Glacier front variatons in Sweden: 2015-2022

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Martin Houssais; [2023]
   Nyckelord :Swedish glaciers; Glacier front variation; Remote sensing; MaQiT; Sentinel-2; Handheld GNSS; UAV photogrammetry; Total station;

   Sammanfattning : This study aims at increasing the amount of data available on recent past Swedish glacier front variations, at improving the knowledge on the present behavior of these glaciers, and at contributing to the defnition of the guideline for future of glacier front observations in Sweden. To do so, the study proposes Sentinel-2 based yearly front variation measurements for 22 Swedish glaciers between 2015 and 2022, calculated based on the multicentreline approach of the MaQiT tool.

3. 2. Shallow near-surface lapse rates and their connection to glacier meteorology on Storglaciären and Rabots glaciär, Northern Sweden

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Moon Taveirne; [2022]
   Nyckelord :Temperature lapse rate; glacier meteorology; near-­surface lapse rate; ablation gradient;

   Sammanfattning : Glacier melt is strongly impacted by climate and meteorology. Temperature lapse rates are used to model glacier melt, and the accuracy of the spatial distribution of modelled melt can be impacted by the lapse rate used in modelling. Additionally, the observed spatial distribution of melt is highly temporally variable. LÄS MER

4. 3. Spatial Variability in Winter Balance on Storglaciären Modelled With a Coupled Terrain Based Approach

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Yoram Terleth; [2021]
   Nyckelord :mass balance; accumulation; snow transport; snow drift; avalanches; glaciology;

   Sammanfattning : Although most processes governing the surface mass balance on mountain glaciers are well understood, the causes and extent of spatial variability in accumulation remain poorly constrained. In the present study, the EBFM distributed mass balance model is newly coupled to terrain based modelling routines estimating mass redistribution by snowdrift, preferential deposition, and avalanching (ST-EBFM) in order to model winter balance on Storglaciären, Sweden.

5. 4. Cold Surface Layer Dynamics of Storglaciären, Northern Sweden 2009-2019

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Shunan Feng; [2019]
   Nyckelord :Storglaciären; cold surface layer; cold-temperate transition surface; polythermal glacier; Storglaciären; kallt ytskikt; kall-tempererad is; polyterrmal glaciär;

   Sammanfattning : Storglaciären is a sub-Arctic polythermal glacier in northern Sweden. Twenty years' monitoring of thecold surface layer found that it has lost one third of its total volume of cold ice with an average thinningrate of 0.80 ± 0.24 m·a-1 for the period of 1989-2009. LÄS MER

7. 5. Optimering av den skandinaviska massbalansmetoden på Storglaciären, Kebnekaisemassivet

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Hannah Fahlborg; Emma Flodin; [2017]
   Nyckelord :Mass balance; climate; Storglaciären; the scandinavian method; optimization; Massbalans; klimat; Storglaciären; skandinaviska metoden; optimering;

   Sammanfattning : Klimatförändringar har direkt påverkan på glaciärers tillväxt och avsmältning. Genom att studera glaciärers massbalans kan framtida riskbedömningar, för bland annat havsytans stigning, uppskattas. LÄS MER
