1. 16. Determination of depositional environment and luminescence dating of Pleistocene deposits in the Biely Váh valley, southern foothills of the Tatra Mountains, Slovakia

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Ingrid Bejarano Arias; [2020]
   Nyckelord :Luminescence dating; glacifluvial deposits; sedimentological analysis; High Tatra Mountains; IRSL dating.; Earth and Environmental Sciences;

   Sammanfattning : The Tatra Mountains have had several glaciations during the Quaternary. The deposits located in the southern foothills were classified as glacifluvial, based on geomorphology, but its sediments have not been studied in detail. LÄS MER

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

   Master-uppsats, Lunds universitet/Geologiska institutionen

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

   Sammanfattning : 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. LÄS MER

4. 18. 2D Effects of Geomorphology and Discharge on Hyporheic Exchange—a HEC-RAS Modelling Study

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Olivia Preston; [2020]
   Nyckelord :average hyporheic exchange velocity; water surface elevation; water surface concavity; hydrostatic head;

   Sammanfattning : Hyporheic exchange is an ecologically and biogeochemically essential function of rivers and streams. One important driver of hydrostatic (hyporheic) exchange is gra- dients in the hydrostatic hydraulic head at the streambed. LÄS MER

5. 19. Eoliska avlagringar och vindriktningar under holocen i och kring Store Mosse, södra Sverige

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Tim Bjermo; [2019]
   Nyckelord :Store Mosse; optiskt stimulerad luminiscens OSL ; kvartsdatering; flygsand; eoliska dyner; holocen; fjärranalys; LiDAR; optically stimualted luminiscence OSL ; quartz dating; aeolian sand; aeolian dunes; Holocene; remote sensing.; Earth and Environmental Sciences;

   Sammanfattning : Eoliska sanddyner är en sällan undersökt resurs ur ett paleoklimatperspektiv. Genom att undersöka dynernas geomorfologi och strukturer kan de klassificeras som olika dyntyper. Eoliska sanddyner kräver speciella omständigheter och förutsättningar för att bildas och agerar värdefulla klimatarkiv för de tidperioder då de avsatts. LÄS MER

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

   Master-uppsats,

   Författare :Taisiya Dymova; [2018]
   Nyckelord :;

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