  1. 6. 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

  2. 7. 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

  3. 8. 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

  4. 9. A comparison of modelled precipitation in Greenland

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Rebecca Vesterberg; [2017]
    Keywords : Greenland; precipitation; Surface mass balance; SMB; ice sheet; accumulation; ablation; sea level rise; Regional Climate Model; HIRHAM5; Numerical Weather Prediction model; HIRLAM7.3; biases; climate change; Physics and Astronomy;

    Abstract : The Greenland ice sheet develops throughout the year with the changing weather condi- tions. Precipitation contributes by increasing the mass, whilst warmth induces melting, which makes the ice sheet diminish. READ MORE

  5. 10. Investigating Seasonal Snow in Northern Sweden – a Multi-Layer Snow Pack Model and Observations from Abisko Scientific Research Station Provide Clues

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Anna Staffansdotter; [2017]
    Keywords : Snow characteristics; snow layer development; snow pack modelling; climate change; Abisko Scientific Research Station; Snöegenskaper; snöskiktutveckling; snöpackmodell; klimatförändringar; Abisko naturvetenskapliga station;

    Abstract : Meteorological parameters determine the physical properties of snow precipitating from the atmosphere, but snow layers also continue to develop within the snow pack after the precipitation event. New characteristics form depending on temperature fluctuations, interaction with the soil, overburden compression, rain-on-snow events and more. READ MORE
