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

    Detta är en avhandling från Stockholm : Stockholm Resilience Centre, Stockholm University

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

    Sammanfattning : 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. Baltic Sea from Space The use of ocean colour data to improve our understanding of ecological drivers across the Baltic Sea basin – algorithm development, validation and ecological applications

    Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Författare :Dmytro Kyryliuk; Stockholms universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean Colour; MERIS; OLCI; water quality; marine ecology; coastal areas; Baltic Sea; marin ekologi; Marine Ecology;

    Sammanfattning : Coastal areas are the most densely populated areas in the world and thus are under immense anthropogenic pressure. To ensure their function and ecological role, coastal areas require continuous monitoring and management. The rapidly emerging field of satellite remote sensing provides a unique opportunity to monitor both land and oceans from Space. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Maria Norman; Uppsala universitet.; [2013]
    Nyckelord :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;

    Sammanfattning : 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.

  4. 4. Light conditions in seasonally ice-covered waters within the Baltic Sea region

    Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant Sciences

    Författare :Elina Kari; Stockholms universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seasonal sea ice; Fast ice; Drift ice; Phytoplankton spring bloom; Under-ice plume; Turbidity; Suspended particulate matter; Chlorophyll; Coloured dissolved organic matter; Baltic Sea; marin ekologi; Marine Ecology;

    Sammanfattning : Seasonal ice cover is a major driver of seasonality in aquatic ecosystems in the Baltic Sea region. Ice cover influences the underwater light conditions directly by limiting the light transfer and indirectly by modifying the mixing and circulation under the ice. LÄS MER

  5. 5. Mesoscale Processes over the Baltic Sea

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Nina Svensson; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary layer; Baltic Sea; stable conditions; low-level jet; sea breeze; boundary layer rolls; mesoscale effects; WRF; LIDAR;

    Sammanfattning : The objective of this thesis is to study mesoscale processes above the Baltic Sea, which is a small, semi-enclosed sea where land-sea interaction may have a large impact on the offshore conditions. It is only the last tens of years that offshore research has become more popular, and one reason for this is the increasing offshore wind energy, which poses the need for accurate estimates of wind speed and turbulence conditions in the marine environment.
