  1. 1. Predicting the future summer range of a declining Arctic waterfowl: the Greenland White-fronted Goose (Anser albifrons flavirostris)

    Kandidat-uppsats,

    Författare :Emil Lundahl; [2022]
    Nyckelord :;

    Sammanfattning : This study investigates what the future might hold for an endemic goose species, found exclusively in the low Arctic region of West Greenland. Facing a decline since four decades, the Greenland White-fronted Goose constitutes one of few goose populations showing a declining trend. LÄS MER

  3. 2. A Lead (Pb) Mass-Balance Budget for a Dry Periglacial Catchment in West Greenland : Discussing the fate of pollutant Pb

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Andreas Nylund; [2020]
    Nyckelord :Lead mass-balance budget; Dry periglacial landscape; Whole catchment; Pollution; Climate change;

    Sammanfattning : Lead (Pb), occurs both naturally and as a pollutant in Arctic landscape systems. The ongoing climate change, especially pronounced in the Arctic, changes the premises for Pb transport and mobility. LÄS MER

  4. 3. Impactites from the Hiawatha crater, North-West Greenland

    Master-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

    Författare :Jacob Gustafsson; [2020]
    Nyckelord :Hiawatha; impact crater; Cape York; Baffin Bay; Greenland Ice Sheet; Younger Dryas; meteorite; impactite; organic carbon; conifer; vitrinite reflectance; Ro; cellular texture; chromite; chromium isotope; toasted quartz; ballen quartz; melted carbonate; granular zircon; planar deformation feature;

    Sammanfattning : The recent discovery of the 31-km-wide Hiawatha impact crater has raised unanswered questions about its age, impactor and highly unusual organic carbon component. Previous research suggests a fractionated iron meteorite impactor, a probable maximum 3–2.4 Ma impact age and a possible Younger Dryas impact age. LÄS MER

  5. 4. Assessment of Drone-Borne Multispectral Mapping in the Exploration of Magmatic Ni-Cu Sulphides – an Example from Disko Island, West Greenland

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Ethan Barnes; [2020]
    Nyckelord :mineral exploration; UAV; multispectral sensors; Illukunnguaq dyke; Greenland;

    Sammanfattning : The senseFly eBeePlus fixed-wing drone is a market available UAV compatible with a range of sensors that includes the Parrot Sequoia+ multispectral camera. Commercial applications of the drone predominantly focus on agriculture, environmental management, and engineering applications. LÄS MER

  7. 5. Arctic Loess as an Environmental Archive : Identifying Weathering with XRF Analysis in West Greenland

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Isabelle Karnik; [2019]
    Nyckelord :loess; XRF; weathering index; Holocene climate; Greenland;

    Sammanfattning : Loess from west Greenland was studied to evaluate Holocene paleoclimate in the Arctic region. Deposits of loess are formed over long time scales through deposition of fine aeolian sediment and they exist in several places in the world. LÄS MER
