1. 1. A re-investigation of hummocky moraine formed from ice sheet decay using geomorphological and sedimentological evidence in the Vomb area, southern Sweden

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Tim Bjermo; [2022]
   Nyckelord :glacial geomorphology; remote sensing; LiDAR; sedimentology; glacitectonite; deformation structures; hummocky moraine; quaternary geology; deglaciation; glacial geomorfologi; fjärranalys; sedimentologi; glacitektonit; deformationstrukturer; småkullig morän; backlandskap; moränlandskap; kvartärgeologi; Earth and Environmental Sciences;

   Sammanfattning : Glacial sediment-landform assemblages have long been used to reconstruct the dynamics of ice sheets throughout the Quaternary time period, particularly so for the period of the last glaciation in northern Europe and southern Scandinavia. One such sediment-landform assemblage is hummocky moraine, which has previously been used as an all-encompassing descriptive terminology strongly associated with dead ice meltout and passive deglaciation.

3. 2. En exkursionsguide till Uppsala läns kvartärgeologiska landskapsutveckling

   Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Linus Strömberg; Emil Henriksson; Axel Fremling; [2021]
   Nyckelord :Excursion guide; geology of Uppsala; quaternary; last glaciation; esker; Exkursionsguide; Uppsala geologi; kvartär; istiden; rullstensås;

   Sammanfattning : Detta kandidatarbete har haft som mål att ta fram en exkursionsguide för naturvetenskapsstudenter som är i ett tidigt stadie i deras utbildning och för den intresserade allmänheten. Syftet har varit att exkursionsguiden ska ge en översiktlig version av Uppsala läns kvartärgeologiska landskapsutvecklingsom är lätt för potentiella läsare att ta till sig. LÄS MER

4. 3. Foreland evolution of Blåisen, Norway, over the course of an ablation season

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Alexander Hamilton-Foyn; [2020]
   Nyckelord :Geomorphological Mapping; Structure from Motion; Glacial Landforms; Ice-Marginal Landforms; Landform Preservation; Hardangerjøkulen; Norway; Earth and Environmental Sciences;

   Sammanfattning : This study presents a detailed investigation into the evolution of sedimentary landforms over an ablation season at Blåisen, an outlet of the Hardangerjøkulen Icecap, Norway. The two visits to Blåisen, one each side of the ablation season, allowed the preservation and evolution of the landforms to be studied. LÄS MER

5. 4. Geomorphology alteration effects over Kävlinge River Basin

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Erik Frias Olguin; [2020]
   Nyckelord :Kävlingeån; DEM; Flooding; Geomorphology; model; MIKE HYDRO; Technology and Engineering;

   Sammanfattning : This thesis focuses on the case study over the Kävlinge catchment located in the south of Sweden, and mainly in the Kävlinge river. This river, which is the mainstream of the catchment, has been subject to modifications due to agricultural activities. LÄS MER

7. 5. Implications of a rapidly thinning ice-margin for annual moraine formation at Gornergletscher, Switzerland

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Lukas Rettig; [2020]
   Nyckelord :Recessional moraines; Ice-marginal processes; Glacier retreat; Glacial geomorphology; Glacial sedimentology; Alpine glaciers; Swiss Alps; Earth and Environmental Sciences;

   Sammanfattning : This study examines genetic processes and climatological significance of annual moraine formation in the foreland of Gornergletscher, a large alpine-valley glacier located in the southern Swiss Alps. A particular focus is set on moraine ridges that have been forming between 2007 and 2019, a period when the glacier has been subject to accelerated retreat and pronounced frontal thinning. LÄS MER
