    Abstract : A composite sediment sequence, consisting of a Russian core and an overlapping freeze core, comprising the uppermost meter of the sediment record, was retrieved from Lake Inre Abborrtjärn in the Torneträsk valley in Lappland, northern Sweden. The core was subsampled for analysis of organic matter content, inorganic carbon content and analysis of the sediment composition using a technique known as structural analysis, resulting in a high-resolution data set spanning the last 2000 years.

    Abstract : When sampling watercourses for environmental assessment it is not feasible to sample all the headwaters or at least not a large fraction of them. This because of the great number of headwaters and their variability in both flow and water chemistry. READ MORE

  3. 18. The effects of water chemistry on fish species distribution : a comparison between isolated and connected lakes in northern Sweden
