  1. 1. 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

  2. 2. Replacement of fish protein in fish feed : effects on the yeast flora in the gut of Arctic charr (Salvelinus alpinus)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Hanna Rydmark; [2023]
    Keywords : Microbiota; Saccharomyces cerevisiae; fishmeal; mussel meal; Mytilus edulis; aquaculture;

    Abstract : The aim with this study was to investigate how feeds with different protein sources influence the levels and composition of the yeast flora in the gut of Arctic charr (Salvelinus alpinus). Arctic charr were fed for two weeks on a control diet (C) with fishmeal (FM) or experimental diets with 40% FM replaced by yeast (Saccharomyces cerevisiae) (Y), meal from blue mussel (Mytilus edulis) (M) or a feed with Baltic Sea originated protein; 33% FM, 33% mussel meal (MM) and 33% S.

  3. 3. Comparison of temperature variability and trends in Svalbard and Franz Joseph Land

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

    Author : Johanna Renberg; [2022]
    Keywords : Arctic warming; Arctic Amplification; Franz Joseph Land climate; Svalbard climate; linear regression;

    Abstract : Arctic warming is assumed to be four times the global warming. A published study by Ivanov et al. (2019) shows that the annual average temperature of Franz Joseph Land (the world’s northernmost island region, a Russian territory) has increased by 5.2 °C from 2000-2017. READ MORE

  4. 4. Arctic amplification and their relation to regional warming

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Marianne Olsson; [2022]
    Keywords : Arctic; arctic amplification; climate; climate change; global warming; metrics; Earth and Environmental Sciences;

    Abstract : Arctic amplification (AA) is defined as the enhanced warming of the surface temperatures in the Arctic region relative to the globe or Northern Hemisphere (NH) in response to external forcings. It is a prominent feature of the climate system. READ MORE

  5. 5. Feedback effects in the Arctic region and how they affect the global climate

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Lotta Nyman; [2020]
    Keywords : Arctic warming; Arctic change; Climate feedback effect; Lower latitude weather; Arctic amplification; Permafrost; Earth and Environmental Sciences;

    Abstract : The Arctic is warming at a rate two to three times that of the global average. Although only covering a small area of the globe, it is a vital component of the climate system. Through climatic feedback effects the warming is enhanced, and risks leading to further climate change. READ MORE
