  2. 11. Mapping bathymetry : From measurement to applications

    Author : Benjamin Hell; Martin Jakobsson; Michele Rebesco; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean and coastal mapping; Digital Bathymetric Model; Geographical Information System; Applications of bathymetric data; Baltic Sea; Arctic Ocean; Seafloor morphology; Ocean circulation; Other earth sciences; Övrig geovetenskap; Marine Geoscience; marin geovetenskap;

    Abstract : Surface elevation is likely the most fundamental property of our planet. In contrast to land topography, bathymetry, its underwater equivalent, remains uncertain in many parts of the World ocean. Bathymetry is relevant for a wide range of research topics and for a variety of societal needs. READ MORE

  4. 12. Predicting Ecosystem Response from Pollution in Baltic Archipelago areas using Mass-balance Modelling

    Author : Olof Magnus Karlsson; Andreas Bryhn; Lars Håkanson; Per Jonsson; Mikael Malmaeus; Kristoffer Naes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; archipelagos; aquatic ecosystems mass-balance modelling; sediment-water dynamics; phosphorus; dioxins; PCDD Fs; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Baltic archipelago areas have high nature values despite being polluted from various antrophogenic activities within the Baltic Sea catchment area and from long-range transport of airborne substances. The discovery of environmental problems in the Baltic Sea in the 1960s led to countermeasures that gradually gave results in reducing the toxic pollution, e. READ MORE

  5. 13. Form and Function of Coastal Areas

    Author : Dan Lindgren; Andreas Bryhn; Lars Håkanson; Lars Brydsten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coastal areas; morphometry; geographic information systems; GIS; ecological value; wave exposure; sediment; bottom dynamic conditions; mass balance modeling; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

    Abstract : Coastal waters have high biological productivity and provide goods and services with a high monetary value. Coasts are used by many different stakeholders and are often densely populated. READ MORE

  6. 14. Context Sensitive Transformation of Geographic Information

    Author : Ola Ahlqvist; Peter Fisher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geographic information; geographic context; semantic models; conceptual models; interoperability; uncertainty; scale; classification; rough sets; fuzzy sets; decision support; Other earth sciences; Övrig geovetenskap;

    Abstract : This research is concerned with theoretical and methodological aspects of geographic information transformation between different user contexts. In this dissertation I present theories and methodological approaches that enable a context sensititve use and reuse of geographic data in geographic information systems. READ MORE

  7. 15. Hydrogeochemistry of Fe and Mn in small boreal catchments

    Author : Louise Björkvald; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogeochemistry; Fe; Mn; boreal catchments; spring flood; Other earth sciences; Övrig geovetenskap;

    Abstract : It is suggested that the overall understanding of the general hydrogeochemistry of a region is best understood from a landscape perspective. If so, this can provide useful information when planning monitoring programmes and influence of human activity. READ MORE
