    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geodetic reference system; geoid potential; global vertical datum; climate change; global warming; mass change; ice melting; sea-level change; remote sensing; satellite gravimetry; geodetiska referenssystem; geopotential; globala vertikala datum; klimatförändring; global uppvärmning; massförändring; issmältning; havsnivåförändring; fjärranalys; satellitgravimetri;

    Sammanfattning : Our complex planet is continuously undergoing temporal and spatial changes. In this context, ongoing processes in the Earth subsystems (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) cause changes in the gravity field of the Earth across a wide range of temporal and spatial scales.

  5. 14. Multispectral reflectance measurements and signature analysis

    Författare :Wolter Arnberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The use of aerial photographs and satellite images may be.facilitated by a deeper knowledge of the reflection properties of natural features. This thesis, which includes a concluding essay and three more papers, is a study of two methods of multispectral reflectance measurements. LÄS MER

  7. 15. Land Degradation and Climate in Iceland - a spatial and temporal assessment

    Författare :Rannveig Olafsdottir; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spatial analysis; long-term analysis; Holocene; spatial simulations; Iceland; Geology; fysisk geografi; physical geography; Geologi; land cover; farmers perception; Land degradation;

    Sammanfattning : Degradation of vegetation and soil erosion has contributed to loss of biological productivity and land degradation in Iceland. This thesis focuses on spatial and temporal patterns of land degradation in Iceland from a geographical perspective both along short and long timescales. LÄS MER
