  2. 1. Landscape from space : geographical aspects on scale, regionalization and change detection

    Author : Ola Hall; Risto Kalliola; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Regionalization; Scale; Change detection; Multiscale analysis; Objectspecific analysis; Watershed transformation; Landscape; Satellite data; Geography; Complex systems theory; Fuzzy set theory; Multicriteria-evaluation.; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Abstract : Landscapes are complex systems composed of multiscale hierarchically organized entities that interact within unique spatial and temporal scales. These interactions result in scaledependent spatial patterns that visually change depending upon the scale at which they are observed. READ MORE

  4. 2. An inductive approach to the modeling of lake water quality in dimictic, glacial/boreal lakes

    Author : Tomas K. E. Thierfelder; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

    Abstract : To explore the interaction between elements of the watershed and lake water quality, a database large enough to approximate the generic population of dimictic, glacial/boreal lakes is assembled and analyzed with multivariate statistical methods in an inductive top-down approach. Utilizing the analytical capabilities of geographical information systems, the spatially distributed characteristics of land cover, soil and bedrock elements are identified and parameterized with respect to element morphology and hydrology.

  5. 3. Mass balance of perfluoroalkyl acids in the Baltic Sea

    Author : Marko Filipovic; Urs Berger; Michael McLachlan; Bert Ove Lund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFOA; PFOS; mass balance; Baltic Sea; PFOA; PFOS; massbalans; Östersjön; miljökemi; Environmental Chemistry;

    Abstract : Perfluoroalkyl acids (PFAAs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer applications, such as constituents in fire fighting foams, hydraulic oils and food packaging materials. READ MORE
