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

    University essay from Stockholms universitet/Institutionen för naturgeografi

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Geologiska institutionen

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

    Abstract : 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. READ MORE

  4. 3. Processes of lateral moraine formation at a debris-covered glacier, Suldenferner (Vedretta di Solda), Italy

    University essay from Lunds universitet/Geologiska institutionen

    Author : Monika Rabanser; [2019]
    Keywords : Lateral moraines; Moraine genesis; Moraine stability; Debris-covered glaciers; Clast shape; Alps; Sedimentology; Glacier fluctuations; Earth and Environmental Sciences;

    Abstract : Lateral moraines are key features of glacial landscapes in high-alpine mountain areas. Research on lateral moraine formation is mostly limited to clean-ice glaciers; lateral moraine formation at the margins of debris-covered glaciers is currently poorly understood in an Alpine and sedimentological context.

  5. 4. Glacial history of the upper Drac Blanc catchment (French Alps)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Felix Martin Hofmann; [2018]
    Keywords : Physical Geography; 10Be exposure dating; structure-from motion; geomorphological mapping; moraine; equilibrium line altitude; Alps; Earth and Environmental Sciences;

    Abstract : Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. READ MORE

  6. 5. Investigating methods for identifying paleo surge-type glaciers or highly dynamical ice flows in Trygghamn, west Spitsbergen

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Åsa Wallin; [2016]
    Keywords : ;

    Abstract : Surge-type glaciers exhibit a cyclic behaviour with an ice mass increase in the reservoir area during the inactive, quiescent phase and a rapid transportation of ice during the active, surge phase. In order to interpret the effects of climate change correctly it is important to distinguish between advances of surge-type glaciers and those of ‘normal’ glaciers, caused by climatic fluctuations.
