  1. 16. Drones in Arctic Environments: Snow Change Tracking Aid using Sensor Fusion

    University essay from 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

  3. 17. 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. 19. 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

  6. 20. Local pollution and the risks of OPFR, PBDE and PFAS to the marine ecosystem outside Longyearbyen and Barentsburg in Svalbard

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Anna Olsson; [2016]
    Keywords : Local pollution; Organophosphorus flame retardants; Polybrominated diphenyl ethers; Perfluorinated alkylated substances; Sediment; Arctic; Svalbard; Adventfjorden; Grønfjorden; Risk analysis; Earth and Environmental Sciences;

    Abstract : Most of the ecotoxicological research conducted in the Arctic until today has focused on long range transport of pollutants, while fewer studies on local pollution have been published. The aim of this study was hence to investigate if local pollution of organophosphorus flame retardants (OPFRs), polybrominated diphenyl ethers (PBDEs) and perfluorinated alkylated substances (PFAS) occurs outside two settlements in Svalbard; Longyearbyen and Grønfjorden.
