  1. 1. 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
