  2. 6. Self-calibration and direct georeferencing in terrestrial laser scanning

    Author : Yuriy Reshetyuk; Lars E. Sjöberg; Milan Horemuz; Hansjörg Kutterer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terrestrial laser scanning; self-calibration; direct georeferencing; error sources; Surveying; Lantmäteri;

    Abstract : An important step in data processing from terrestrial laser scanning (TLS) is georeferencing, i.e. transformation of the scanner data (point clouds) into a real world coordinate system, which is important for their integration with other geospatial data. READ MORE

  4. 7. Molecular and isotopic characterization of terrestrial organic carbon released to (sub-)Arctic coastal waters

    Author : Jorien Elisabeth Vonk; Örjan Gustafsson; Jason Neff; Stockholms universitet; []
    Keywords : organic carbon; terrestrial biomarkers; radiocarbon; particulate organic carbon; sediments; sphagnum; Arctic; Bothnian Bay; East Siberian Sea; Kalix River; Kolyma River; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Arctic soils store half of the global soil organic carbon (OC) pool and twice as much C as is currently present in the atmosphere. A considerable part of these carbon pools are stored in permafrost. READ MORE

  5. 8. Global Changes and European Terrestrial Ecosystems

    Author : Emmanuel Gritti; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; European species; Climatic risk; pedology; cartography; climatology; Fysisk geografi; geomorphology; Physical geography; Vegetation modelling; Pollen analysis; Plant invasion; geomorfologi; marklära; kartografi; klimatologi; Global Changes;

    Abstract : Global environmental changes are topics of important societal concern and current scientific interest. These changes are driven by many different forcing and feedbacks occurring at various time and geographic scales and are largely influencing the various Earth systems. READ MORE

  6. 9. Resonant Waves in the Terrestrial Magnetosphere

    Author : Tommy Eriksson; Lars Blomberg; Stephan Buchert; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Abstract : Waves in the mHz frequency range are a prominent feature in the terrestrial magnetosphere. In this frequency range the waves have wavelengths comparable to the lengths of the geomagnetic field lines. The waves are then standing waves along closed field lines with endpoints in the southern and northern ionosphere. READ MORE

  7. 10. Phytoremediation of mercury by terrestrial plants

    Author : Yaodong Wang; Maria Greger; Lena Kautsky; Douglas Godbold; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoremediation; phytoextraction; phytostabilization; bioavailability; willow; Hg; Plant physiology; Växtfysiologi;

    Abstract : Mercury (Hg) pollution is a global environmental problem. Numerous Hg-contaminated sites exist in the world and new techniques for remediation are urgently needed. READ MORE
