  1. 26. Acoustic survey of sea floor features in Asköfjärden

    Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Kim Lundmark; [2017]
    Nyckelord :Marine Geology; Marine Geophysics; Multibeam; Sub-bottom Profiler; Stockholm Archipelago; Geomorphology; Baltic Sea; Gas Seeps; Methane Gas; Fluid Migration; Groundwater; Acoustic Units; Sediment Profile;

    Sammanfattning : Marine geological surveys in Asköfjärden in the southern Stockholm Archipelago hasrevealed step like features in the sediments on the Baltic sea floor. The aim of this project is toanalyse the steps and possible formation processes from the survey data. LÄS MER

  2. 27. Paleoglaciological study of the Ahlmannryggen, Borgmassivet and Kirwanveggen nunatak ranges, Dronning Maud Land, East Antarctica, using WorldView imagery

    Master-uppsats,

    Författare :Elena Serra; [2017]
    Nyckelord :;

    Sammanfattning : Paleoglaciological reconstructions based on glacial geological and geomorphological evidence areused to constrain and test numerical models of ice sheet extent and dynamics. The MAGIC-DMLresearch project (“Mapping, Measuring and Modelling Antarctic Geomorphology and Ice Change, inDronning Maud Land”) is trying to reconstruct the timing and pattern of ice surface elevation changessince the mid-Pliocene across western Dronning Maud Land, East Antarctica.

  3. 28. Dynamics of a retreating ice sheet : a LiDAR study in Värmland, SW Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Alastair Goodship; [2017]
    Nyckelord :LiDAR; SIS; retreat; deglacial; DEM; geomorphology; Värmland; Earth and Environmental Sciences;

    Sammanfattning : Värmland in south central Sweden lies across the established zone of aquatic-terrestrial transition of the Scandinavian Ice Sheet margin during its rapid final retreat following the Younger Dryas. Recently acquired LiDAR data across Värmland allows more highly detailed observation and analysis of glacial landforms formed during this stage than has previously been possible. LÄS MER

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

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Åsa Wallin; [2016]
    Nyckelord :;

    Sammanfattning : 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.

  5. 30. Diatom distribution in the lower Save river, Mozambique : Taxonomy, salinity gradient and taphonomy

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Marie Christiansson; [2016]
    Nyckelord :Diatoms; Quaternary geology; micropaleontology; taphonomy; taxonomy; siliceous microfossils;

    Sammanfattning : In this study diatom distribution within the lower Save River, Mozambique, has been identified from surface sediments, surface water, mangrove cortex and buried sediments. Sandy units, bracketing a geographically extensive clay layer, have been dated with optical stimulated luminescence (OSL). LÄS MER
