  3. 2. Tracing anthropogenic Technology Critical Elements using Environmental Forensics : Case studies at Kallholmsfjärden and the Bothnian Bay, northern Sweden

    Författare :Stacy Sutliff-Johansson; Anders Widerlund; Kristi Korkka-Niemi; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental Forensics; Technology Critical Elements; Sediment Contamination; Groundwater Contamination; Contaminant Tracing; Tillämpad geokemi; Applied Geochemistry;

    Sammanfattning : The rapidly changing landscape of today's technology industry has increased the number of electronic products being discarded. Society is always on the hunt for the latest product and newest technological advancement, thereby creating a constant influx of older model products into fast-growing waste streams. LÄS MER

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

    Författare :Jorien Elisabeth Vonk; Örjan Gustafsson; Jason Neff; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. The dynamics in harvested populations

    Författare :Anders Wikström; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluctuations; temporal; state-space; Harvest; cod; vendace; elasticity; stage-structured; stochastic; growth-rate; Baltic Sea; Bothnian Bay;

    Sammanfattning : We are interested in the effect of harvesting on population fluctuations and for that purpose we develop and analyze an age-structured model where recruitment is a stochastic process and the adult segment of the population is harvested. When a constant annual harvest is taken the coefficient of variation of the adult population increases for most parameter values due to the age truncation effect, i. LÄS MER
