  1. 1. Periglacial and glacial landform mapping in the Las Veguitas catchment, Cordillera Frondal of the Andes (Argentina).

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Eirini Makopoulou; [2018]
    Nyckelord :Geomorphological map; thermokarst lakes; glaciers; GIS; Argentinian Andes; spatial and temporal analysis;

    Sammanfattning : The semi-arid and arid Andes of South America are characterized by large areas with glacial and periglacial environments. This study focusses on the distribution of glacial and periglacial landforms in the Las Veguitas catchment, Cordillera Frontal, Argentina. LÄS MER

  2. 2. Sedimentology and Catchment Processes of Lake Bolterskaret, Svalbard

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

    Författare :Matilda Elise Ruth Svensson; [2018]
    Nyckelord :Lacustrine sedimentation; Bolterskaret; late Holocene; Climate change; Varves;

    Sammanfattning : Lacustrine sediments are important archives of landscape and climate evolution. Varved sediments offer a high-resolution archive enabling studies on annual and seasonal scale. Understanding the alteration of sedimentation in glacial lakes under a changing climate is important for paleoclimate reconstructions. LÄS MER

  3. 3. Development of a method for mapping the highest coastline in Sweden using breaklines extracted from high resolution digital elevation models

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

    Författare :Anna Lundgren; [2016]
    Nyckelord :Physical Geography and Ecosystem analysis; Geographical Information Systems; GIS; the highest coastline; Geological Survey of Sweden; SGU; high resolution digital elevation model; LiDAR; land surface parameter; curvature; breakline extraction; geomorphological mapping; Earth and Environmental Sciences;

    Sammanfattning : [b]Utveckling av en metod för att kartera högsta kustlinjen i Sverige med hjälp av brytlinjer extraherade från högupplösta höjdmodeller[/b] Högsta kustlinjens (HK) geografiska läge i landskapet markerar gränsen mellan subakvatiskt och supraakvatiskt avsatta sediment. Idag varierar HKs höjd över havet från några få m.ö.h. LÄS MER

  4. 4. LIDAR-analys av flygsanddyner i Västerbottens inland : Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Fredrik Bogren; [2015]
    Nyckelord :LIDAR; digital elevation model dem ; aeolian sand dunes; till-covered; preserved morphology; LIDAR; digital höjdmodell dem ; flygsanddyner; moräntäckt; bevarad morfologi;

    Sammanfattning : The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. LÄS MER

  5. 5. Geomorphological evidence for an ongoing transgression on northwestern Svalbard

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Kristian Westlund; [2014]
    Nyckelord :sea level; Svalbard; geomorphology; lagoons; estuaries; havsnivå; geomorfologi; laguner; estuarier; Earth and Environmental Sciences;

    Sammanfattning : Rise and fall of the global sea level during Pleistocene and Holocene are mainly caused by glacio-isostatic and glacio-eustatic factors directly linked to the cyclic increase and decrease of the Earth’s ice sheets. Apart from the dominating glacio-isostatic and glacio-eustatic factors, several other components have influenced the global sea level, which complicates the regional sea level curves of the world.
