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

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

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

    Sammanfattning : 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.

  2. 2. Microstructures and Compressive Strength of Lake Ice in Sweden A structural Documentation and Compressive Strength Analysis of Lake Ice Cores from Uppsala, using the SonReb Method

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Julia Ladefoged; [2023-08-18]
    Nyckelord :;

    Sammanfattning : Lake ice have been utilized by humans through centuries, as transportation routes and recreational activities to name a few (Sharma et al., 2019). Despite our frequent usage of lake ice there is a lack of extensive knowledge of it. LÄS MER

  3. 3. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jakob Gunnarsson; [2023-05-10]
    Nyckelord :;

    Sammanfattning : Polynyas are recurring areas of open water or thin ice within the sea ice pack, which alter the local oceanatmosphere heat and moisture exchange. They are differentiated as coastal (latent heat) or open-ocean (sensible heat) polynya according to their formation process. LÄS MER

  4. 4. The implications of heavy fuel oil ban in arctic waters for sustainable arctic shipping

    Master-uppsats, Göteborgs universitet/Institutionen för marina vetenskaper

    Författare :Kaung Thu; [2023-01-23]
    Nyckelord :Arctic region; heavy fuel oil; shipping; Sustainable;

    Sammanfattning : The increased temperature in the polar regions is one of the significant impacts of global warming and consequential climate change. In the Arctic, regional warming leads to the accelerated loss of sea ice caps, which has opened up new international shipping routes. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

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

    Sammanfattning : 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. LÄS MER
