  1. 1. Direct multispectral photogrammetry for UAV-based snow depth measurements

    University essay from KTH/Geoinformatik

    Author : Kathrin Maier; [2019]
    Keywords : Unmanned Aerial Vehicles UAV ; snow depth; direct photogrammetry; multispectral imagery; cryosphere;

    Abstract : Due to the changing climate and inherent atypically occurring meteorological events in the Arctic regions, more accurate snow quality predictions are needed in order to support the Sámi reindeer herding communities in northern Sweden that struggle to adapt to the rapidly changing Arctic climate. Spatial snow depth distribution is a crucial parameter not only to assess snow quality but also for multiple environmental research and social land use purposes. READ MORE

  2. 2. Snow layer mapping by remote sensing from Unmanned Aerial Vehicles : A mixed method study of sensor applications for research in Arctic and Alpine environments

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Isacsson; [2018]
    Keywords : UAV; Drones; Snow; Remote Sensing; Sensors; Arctic; Alpine; Mapping; UAV; Drönare; Snö; Fjärranalys; Sensorer; Arktis; Alpin; Kartläggning;

    Abstract : Examensarbetet presenterat i den här rapporten utfördes i syfte att kartlägga vilka sensorer och metoder som skulle kunna vara tillämpbara inom kartläggning av snölager i den arktiska regionen. För att göra den bedömningen har flera olika metoder använts. READ MORE

  3. 3. Probability Modelling of Alpine Permafrost Distribution in Tarfala Valley, Sweden

    University essay from Uppsala universitet/Luft-, vatten och landskapslära

    Author : Micael Alm; [2017]
    Keywords : Alpine permafrost; BTS; stepwise regression; logistic regression; Tarfala; Alpin permafrost; BTS; stegvis regression; logistisk regression; Tarfala;

    Abstract : Datainsamling har genomförts i Tarfaladalen under 5 dagar vid månadsskiftet mellan mars och april 2017. Insamlingen resulterade i 36 BTS-mätningar (Bottom Temperature of Snow cover) som därefter har använts tillsammans med data från tidigare insamlingar, till att skapa en sammanställd modell över förekomsten av permafrost omkring Tarfala.

  4. 4. A 2D Electrical Resistivity Survey of Palsas in Tavvavuoma, sub-arctic Sweden

    University essay from Uppsala universitet/Luft-, vatten och landskapslära

    Author : Per Marklund; [2014]
    Keywords : Palsas; permafrost; peat plateaus; resistivity; ert; geophysics; Tavvavuoma; Palsar; permafrost; torvplatåer; resistivitet; ert; geofysik; Tavvavuoma;

    Abstract : Electrical resistivity tomography (ERT) is a commonly used geophysical method to investigate permafrost in the mountain environment, but few studies have employed this method in a permafrost affected peatland. For this thesis, 5 ERT profiles were measured over 17 palsas and peat-plateaus in a palsa peatland environment in Tavvavuoma, northern Sweden, where the primary aim was to investigate the depth to the base of permafrost under the mounds.

  5. 5. Atmospheric mecury deposition in alpine snow, northern British Columbia and southwestern Yukon, Canada

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Pia Karlsson; [2014]
    Keywords : ;

    Abstract : High mercury (Hg) levels have been measured in fish in Kusawa Lake (KL), a subalpine, partly glacier-fed lake situated in the southwestern Yukon, Canada, but it is presently unknown where this Hg comes from. One possible source may be atmospheric deposition of Hg in snow and subsequent release by melt into the lake. READ MORE
