  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; Henrik Österblom; Joakim Hjelm; Trevor Branch; [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; Anna Rutgersson; Erik Sahlée; William Drennan; [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; Meteorology; Meteorologi;

    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. Detection and classification of sea ice from spaceborne multi-frequency synthetic aperture radar imagery and radar altimetry

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Wiebke Aldenhoff; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sea ice; sea ice classification; Fram Strait; sea ice concentration; Beaufort Sea; SAR imaging; radar altimetry;

    Abstract : The sea ice cover in the Arctic is undergoing drastic changes. Since the start of satellite observations by microwave remote sensing in the late 1970's, the maximum summer sea ice extent has been decreasing and thereby causing a generally thinner and younger sea ice cover. READ MORE

  4. 4. Carbon Dynamics in Northern Marginal Seas

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Sofia Hjalmarsson; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved inorganic carbon; total alkalinity; continental shelf pump; marginal seas; Baltic Sea; Skagerrak; Laptev Sea; East Siberian Sea; Chukchi Sea;

    Abstract : The marginal seas have, despite their relatively small area, an important role in the global carbon cycle. They are largely influenced by carbon and nutrient fluxes from land and a large part of the biological production occurs in the marginal seas. READ MORE

  5. 5. Mesoscale Processes over the Baltic Sea

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Nina Svensson; Erik Sahlée; Hans Bergström; Anna Rutgersson; Søren Larsen; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Boundary layer; Baltic Sea; stable conditions; low-level jet; sea breeze; boundary layer rolls; mesoscale effects; WRF; LIDAR;

    Abstract : 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.
