  1. 6. 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. 7. Seasonal community dynamics of macroinvertebrates in an Arctic stream

    University essay from

    Author : Ellinor Jakobsson; [2019]
    Keywords : Macroinvertebrates; Arctic; seasonality; community composition; Abisko;

    Abstract : Arctic ecosystems are amongst the most vulnerable on Earth to ongoing climate change. While the responses to these changes are well studied on land, less is known about how aquatic communities may respond to a warmer arctic. READ MORE

  3. 8. 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

  4. 9. Quaternary Arctic foraminiferal isotopes: species reliability and palaeoceanographic application

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Aron Varhelyi; [2018]
    Keywords : Palaeoceanography; Arctic; foraminifera; stable isotopes; Paleoceanografi; Arktis; foraminiferer; stabila isotoper;

    Abstract : To investigate whether foraminiferal stable isotope (δ18O/δ13C) variations have potential as a chronostratigraphic tool in the Arctic Ocean, this thesis presents new δ18O/δ13C data from five marine sediment cores. Three of those are downcore analyses (PS92/54-1; TC/PC-03; PC-07) and the remaining two are core top analyses (PC-04; PC-08). READ MORE

  5. 10. Drones in Arctic Environments: Snow Change Tracking Aid using Sensor Fusion

    University essay from KTH/Mekatronik; KTH/Mekatronik

    Author : Daniela Attalla; Alexandra Tang; [2018]
    Keywords : ;

    Abstract : The Arctic is subject to rapid climate changes that canbe difficult to track. This thesis aims to provide a user case in which researchers in the Arctic benefit from the incorporation of drones in their snow ablation research. This thesis presents a way to measure ablation stakes with the help of a sensor fusion system mounted on a drone. READ MORE
