  1. 1. SEA CHANGE Social-ecological co-evolution in Baltic Sea fisheries

    University dissertation from Stockholm : Stockholm Resilience Centre, Stockholm University

    Author : Jonas Hentati-Sundberg; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; resilience; social-ecological systems; complex adaptive systems; fisheries; Baltic Sea; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : Sustainable management of natural resources requires an in-depth understanding of the interplay between social and ecological change. Linked social-ecological systems (SES) have been described as complex adaptive systems (CAS), which mean that they are irreducible, exhibit nonlinear dynamics, have interactions across scales and are uncertain and unpredictable.

  2. 2. Air-Sea Fluxes of CO2 Analysis Methods and Impact on Carbon Budget

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Maria Norman; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; air-sea exchange; carbon dioxide; Baltic Sea; eddy-covariance method; inertial dissipation method; cospectral-peak method; Baltic Sea measurements; CO2 fluxes; Galathea 3 expedition; Baltic Sea modeling; water-side convection; coastal upwelling; carbon budget; Meteorologi; Meteorology;

    Abstract : Carbon dioxide (CO2) is an important greenhouse gas, and the atmospheric concentration of CO2 has increased by more than 100 ppm since prior to the industrial revolution.  The global oceans are considered an important sink of atmospheric CO2, since approximately one third of the anthropogenic emissions are absorbed by the oceans.

  3. 3. Nitrogen land-sea fluxes in the Baltic Sea catchment Empirical relationships and budgets

    University dissertation from Stockholm : Department of Applied Environmental Science (ITM)

    Author : Hanna Eriksson Hägg; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nitrogen fluxes; Baltic Sea; primary emissions; riverine export; Scenario analysis; climate change; animal protein consumption; fertilizer use; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi; tillämpad miljövetenskap; Applied Environmental Science;

    Abstract : In this thesis empirical relationships and modeling tools are used to describe the relationship between human activities and meso- and large scale riverine N fluxes from land to sea.On a large scale Paper I showed that by only having knowledge about human population size and runoff one can estimate the riverine export of DIN (r2= 0.76).

  4. 4. Bacterioplankton in the Baltic Sea influence of allochthonous organic matter and salinity

    University dissertation from Umeå : Umeå Universitet

    Author : Daniela Figueroa; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bacterioplankton production; bacterial community structure; allochthonous organic matter; carbon utilization; dissolved organic carbon composition; bacterioplankton ecological function; bacterial diversity; bacterial network; Baltic Sea estuary; food web; climate change.; Environmental Science; miljövetenskap;

    Abstract : Climate change is expected to increase the precipitation ~30% in higher latitudes during the next century, increasing the land runoff via rivers to aquatic ecosystems. The Baltic Sea will receive higher river discharges, accompanied by larger input of allochthonous dissolved organic matter (DOM) from terrestrial ecosystems. READ MORE

  5. 5. Multiple forces drive the Baltic Sea food web dynamics and its response to environmental change

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Susa Niiranen; Stockholms universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; climate change; Ecopath with Ecosim; food web interactions; multiple drivers; regime shift; trophic control; marin ekologi; Marine Ecology;

    Abstract : Understanding the interaction of multiple drivers and their compounded effects on ecosystem dynamics is a key challenge for marine resource management. The Baltic Sea is one of the world’s seas most strongly impacted by effects from both human activities and climate. READ MORE
