  1. 1. Insights Into Wind Profile Characteristics in the Arctic Marine Boundary Layer

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Charlotte Sophie Gausa; [2024]
    Keywords : Arctic; wind profile power law; MOST; boundary layer; low level jets; sea ice; vindprofil; Arktis; gränsskikt; vindenergi; låghöjdsvindar; havsis;

    Abstract : The atmospheric boundary layer in the Arctic is essential for the understanding of climate change and improving regional weather prediction. The aim of this study is to investigate to which degree wind speed profiles retrieved in the Arctic agree with well known wind profile concepts and understand which local impact factors influence the wind speed profile.

  3. 2. The bzzzt of frirends. Interspecific competition in Arctic plants for pollination services.

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Malin Olsson; [2023-06-27]
    Keywords : the Arctic; pollinator networks; competition; autonomous selfing; Arktis; pollinationsnätverk; konkurrens; autonom självpollinering;

    Abstract : The Arctic has a harsh environment that is challenging for the flora and fauna that inhabits the region. The ruling abiotic factors of the region results is a low species richness that creates a potential challenge for the region’s plant species. READ MORE

  4. 3. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sara Rognås; [2023]
    Keywords : aeolian transport; loess; grain size analysis; loss on ignition; palaeoclimate; Svalbard; Holocene; vindtransporterat material; lössjord; kornstorlek; loss on ignition; paleoklimat; Svalbard; Holocen;

    Abstract : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. READ MORE

  5. 4. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Albin Andreasson; Noa Lind; [2023]
    Keywords : Svalbard; loess soil; XRF; weathering; climate change;

    Abstract : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.

  6. 5. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Ideström; [2023]
    Keywords : Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Abstract : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. READ MORE
