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

    Author : Robert M. Graham; Agatha de Boer; Alberto Naveira Garabato; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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

  2. 2. 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 : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Southern Ocean; Front; Water mass; Antarctic Polar Front; Descriptive Physical Oceanography; Functional Principal Component Analysis; Elephant Seal; Biologging; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    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).

  3. 3. The Location and Variability of Southern ocean Fronts

    Author : Robert M. Graham; Agatha M. de Boer; Jonas Nycander; Qiong Zhang; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. Moreover, the Subtropical Front (STF) is believed play a key role in the global climate system. READ MORE

  4. 4. Formation and Distribution of Marine Biogenic Halocarbons with Emphasis on Polar Regions

    Author : Anders Karlsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : volatile biogenic halocarbons; Arctic Ocean; Southern Ocean; sea ice; snow; air-sea exchange; cyanobacteria;

    Abstract : It is well-established that marine micro- and macroalgae form volatile halogenated compounds (halocarbons). Production occurs throughout the world ocean with strong regional sources in coastal areas. In the atmosphere, these compounds are converted to reactive inorganic halogen compounds, which degrade ozone. READ MORE

  5. 5. Drivers of Population Dynamics in Bacterioplankton : Spotlight on Alphaproteobacteria and its dominant SAR11 Lineage

    Author : Friederike Heinrich; Stefan Bertilsson; Alexander Eiler; David Kirchman; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; bacterial community dynamics; Alphaproteobacteria; SAR11; LD12; Southern Ocean; lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Bacteria are mediators of biogeochemical cycles and are in this way vital for maintaining life on earth. Their distribution, abundance and functioning are driven by environmental heterogeneity and dynamic change in abiotic and biotic factors. READ MORE
