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

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Isabelle Karnik; [2019]
    Nyckelord :loess; XRF; weathering index; Holocene climate; Greenland;

    Sammanfattning : 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. LÄS MER

  3. 47. Isolation and genomic characterization of three PHA degrading bacteria from the marine environment

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Giulia Elli; [2019]
    Nyckelord :PHA; degradation of PHA; marine bacteria; sulphate reducing bacteria; SRB; SRM; biotechnology; bioteknik; Technology and Engineering;

    Sammanfattning : The broader goal of this project was to investigate what kind of effects the accumulation of polyhydroxyalkanoates (PHA) in the marine environment might have on the microbial world. Bacteria were isolated from biofilms fouling PHA pellets placed in the sediment-water interface; the goal was to isolate PHA degraders that were also sulphate reducers. LÄS MER

  4. 48. Climate Change and Precipitation Variability Influence on the Greenland Ice Sheet

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Jennie Olsson; [2018]
    Nyckelord :Physics; Ice Sheet; Surface Mass Balance; SMB; Representative Concentration Pathways; RCP; Climate Change; Greenland; Precipitation; Precipitation Variability; Glaciers; Glacier; Meteorology; Greenhouse Effect; Greenhouse Gas; Future Climate; Climate; Physics and Astronomy;

    Sammanfattning : Climate changes have a large impact on precipitation patterns and precipitation variability change. With this in mind, precipitation over Greenland is studied. This is done for present day precipitation model data from 1991-2010 compared to future model simulations of precipitation for 2081-2100. LÄS MER

  5. 49. Ice Sheet Modeling: Accuracy of First-Order Stokes Model with Basal Sliding

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eskil Jonsson; [2018]
    Nyckelord :Ice sheet modelling; First-Order Stokes model; basal sliding; Stokes equations;

    Sammanfattning : Some climate models are still lacking features such as dynamical modelling of ice sheets due to their computational cost which results in poor accuracy and estimates of e.g. sea level rise. LÄS MER

  7. 50. Atmospheric soot particle transformation from urban to rural

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Fredrik Johansson; [2018]
    Nyckelord :Aerosol; soot; atmosphere; Physics and Astronomy; Earth and Environmental Sciences;

    Sammanfattning : The main objective of this work was to investigate if there is a contribution of aerosol from the urban region of Copenhagen at the rural station Vavihill. This was done by analyzing measurement data between 1st of January and the 28th of February 2013 measured with a Dierential Mobility Particle Sizer (DMPS), Soot Particle Aerosol Mass Spectrometer (SP-AMS), a Cloud Condensation Nuclei Counter (CCNC) and a NOx-analyzer.
