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

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    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

  2. 2. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alicja Miodonska; [2019]
    Keywords : remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Abstract : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Isabelle Karnik; [2019]
    Keywords : loess; XRF; weathering index; Holocene climate; Greenland;

    Abstract : 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. READ MORE

  5. 5. 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
