  1. 1. LIDAR-analys av flygsanddyner i Västerbottens inland : Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?

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

    Författare :Fredrik Bogren; [2015]
    Nyckelord :LIDAR; digital elevation model dem ; aeolian sand dunes; till-covered; preserved morphology; LIDAR; digital höjdmodell dem ; flygsanddyner; moräntäckt; bevarad morfologi;

    Sammanfattning : The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. LÄS MER
