  1. 1. Tracing pathways in the ocean circulation : A temperature and salinity perspective

    Author : Sara Berglund; Kristofer Döös; Jonas Nycander; Göran Broström; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lagrangian trajectories; Climate modelling; Atlantic Ocean; Southern Ocean; Ocean circulation; heat; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The ocean circulation plays an essential role in our climate system. It redistributes heat, salt, carbon and other tracers across the globe, making the climate of Earth more moderate. This thesis targets density differences that are driving the ocean circulation. These differences are caused by changes in temperature and salinity. READ MORE

  2. 2. The role of Southern Ocean fronts in the global climate system

    Author : Robert M. Graham; Agatha de Boer; Alberto Naveira Garabato; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; fronts; jets; Antarctic Circumpolar Current; wind stress; chlorophyll; iron; Last Glacial Maximum; Marine Geology; maringeologi;

    Abstract : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. However, until recently fronts have been poorly resolved by available data and climate models. READ MORE

  3. 3. Unraveling the thermohaline structure of the Southern Ocean using functional data analysis

    Author : Etienne Pauthenet; Fabien Roquet; Jonas Nycander; Alberto Naveira Garabato; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; Front; Water mass; Antarctic Polar Front; Descriptive Physical Oceanography; Functional Principal Component Analysis; Elephant Seal; Biologging; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The Southern Ocean connects the Indian, Pacific and Atlantic Oceans and provides a direct pathway to exchange mass, heat and salt across the Global Ocean, therefore playing an important role in the global climate system. Due to the complexity of its structure and the general inadequacy of its sampling, both in time and space, it remains a challenge to describe and visualize the three dimensional pattern of its circulation and the associated tracer distribution (temperature, salinity, oxygen or nutrients).

  4. 4. Towards Technology Assessment of Ocean Energy in a Developing Country Context

    Author : Linus Hammar; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electricity; Indian Ocean; technology assessment; ocean energy; Africa; rural electrification; ocean thermal energy conversion; wave power; tidal power;

    Abstract : New technologies for the extraction of valuable ocean resources are emerging: renewable ocean energy. Ocean energy technologies have so far primarily been developed in industrialized countries but will be deployed in both industrialized and developing countries. READ MORE

  5. 5. Turbulence in the sea ice impacted Southern Ocean and its implications for primary production and carbon export

    Author : Isabelle Giddy; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; sea ice; submesoscale; diapycnal mixing; heat fluxes; primary production; carbon export; gliders.;

    Abstract : The sea ice impacted Southern Ocean, south of the Antarctic Circumpolar Current, is one of the most important regions on earth for the cycling of carbon and distribution of heat and freshwater around the globe. Here, along-isopycnal upwelling of warm, carbon-rich circumpolar deep water coincides with the annual growth and melt of Antarctic sea ice that represents one of the worlds largest surface water transformations.
