  1. 11. 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

  3. 12. The Spatial Turn in the Heritage Field : A case study of the Arctic during the crisis of places.

    University essay from Uppsala universitet/Kulturvård

    Author : Cristian Martín Lanzas; [2023]
    Keywords : Human geographies; Arctic; dwelling; Spirit of Place; Phenomenology.;

    Abstract : Modern research on the shared points of natural and cultural heritage has opened new opportunities for the investigation of the dimensions of this natureculture phenomenon. Theo bjective of this study is to develop this subject by analysing the dialogue between the most critical human geographies and the heritage field. READ MORE

  4. 13. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

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

    Author : Alexina Brännlund; [2023]
    Keywords : Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Abstract : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  5. 14. 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. 15. Melting Security – Indigenous Livelihood in the Canadian Arctic

    University essay from Lunds universitet/Graduate School

    Author : Lisa Pohl; [2023]
    Keywords : Paris Agreement; Climate Change; Inuit; Nunavut; Societal Security; Social Sciences;

    Abstract : The COP21 Paris Agreement is considered a milestone on the way to limiting global warming to 1.5°C. For the first time in history, a climate convention is signed by all 198 members of the UNFCCC, with each signatory state being responsible for developing their own climate strategy that considers the national circumstances.
