  1. 1. The Cambrian lophotrochozoans of the Transantarctic Mountains, Antarctica

    University dissertation from Uppsala : Uppsala universitet

    Author : Lewis Bassett-Butt; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Dailyatia; Cambrian; Drumian; Middle Cambrian; Early Cambrian; Antarctica; tommotiid; camenellan; palaeobiology; small shelly fossils; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The origin of many lophotrochozoan groups can be traced to “small shelly fossil” (SSF) faunas of the Early Cambrian. Antarctica is a key region of study, due to the continent’s known close geographical proximity to well-studied Australian and Indian basins in in the Cambrian. READ MORE

  2. 2. Ice Sheet, Climate, and Landscape Interactions in Dronning Maud Land, Antarctica

    University dissertation from Stockholm : Stockholm University

    Author : Jens-Ove Näslund; Stockholms universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antarctica; Basal temperature; Dronning Maud Land; Erosion; Escarpments; Glacial landforms; Ice Sheets; Ice sheet modelling; Landscape development; Palaeosurfaces; Radar; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap Övrig geovetenskap; Physical Geography; naturgeografi;

    Abstract : The impact of glaciers and ice sheets on the subglacial landscape are of fundamental importance for studies of glacial history and landscape development, both in previously glaciated areas and in areas that are glaciated today. The thesis concerns the present and past erosive capacity of the ice sheet in Dronning Maud Land, East Antarctica. READ MORE

  3. 3. Spatial distribution of snow in Antarctica and other glacier studies using ground-penetrating radar

    University dissertation from Stockholm : Department of Physical Geography and Quaternary Geology, Stockholm University

    Author : Cecilia Richardson-Näslund; Stockholms universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GPR; ground-penetrating radar; radar soundings; snow accumulation; accumulation rate; spatial variability; Antarctica; Dronning Maud Land; cold surface layer; thermal regime; glacial cirques; Sweden; Antarktis; Glaciärer; Ackumulering av snö; Geography; Physical Geography; geografi med naturgeografisk inriktning;

    Abstract : The overall aim of this thesis is to develop and exemplify the use of ground-penetrating radar (GPR) within the field of glaciology. The main focus is on the spatial distribution of snow in Dronning Maud Land, East Antarctica. READ MORE

  4. 4. Force Budget Analysis of Glacier Flow Ice Dynamical Studies on Storglaciären, Sweden, and Ice Flow Investigations of Outlet Glaciers in Dronning Maud Land, Antarctica

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jim Hedfors; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical geography and sedimentology; force budget; ice flux; ice dynamics; mass balance; strain heating; climate change; Storglaciären; Dronning Maud Land; Antarctica; Naturgeografi och sedimentologi; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap Naturgeografi;

    Abstract : This thesis contributes to the understanding of glacier response to climate change by ice dynamical studies on Storglaciären, Sweden, and Bonnevie-Svendsenbreen, Kibergbreen and Plogbreen in Dronning Maud Land, Antarctica. Ice surface velocities, ice geometry and temperature information is fed through a force budget model to calculate ice mass outflux of these glacial systems via three-dimensional stress distributions for a flux-gate.

    Abstract : Popular Abstract in Swedish Denna avhandling presenterar data från två olika geografiska områden, Dronning Maud land, Antarktis, och den Skandinaviska fjällkedjan som befinner sig på den Baltiska kontinentalplattan. Dessutom presenteras en jämförande studie mellan två metoder att datera bergarter. READ MORE
