  1. 1. Ocean circulation in the Amundsen Sea, West Antarctica

    Författare :Ola Kalén; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :ocean; currents; icebergs; remote sensing; ocean model;

    Sammanfattning : The increase of mass loss from the Antarctic Ice Sheet is a significant contribution to global sea level rise. The most rapid changes are occurring in the Amundsen Sea area, where the thinning of the floating glaciers is assumed to be driven by the ocean. LÄS MER

  2. 2. Parallelization of the HIROMB ocean model

    Författare :Tomas Wilhelmsson; KTH; []
    Nyckelord :parallelization ocean model; operational forecast; Baltic Sea; multi-frontal solver; domain decomposition; ice dynamics;

    Sammanfattning : .... LÄS MER

  3. 3. Implementation and Analysis of Air-Sea Exchange Processes in Atmosphere and Ocean Modelling

    Författare :Björn Carlsson; Anna Rutgersson; Ann-Sofi Smedman; Öyvind Saetra; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Sensible heat flux; Latent heat flux; Momentum flux; Wind stress; Marine boundary layer; Air–Sea interaction; Swell; Climate model; Ocean model; Roughness parameter; Drag coefficient; Wave breaking; Meteorology; Meteorologi;

    Sammanfattning : To understand and to predict the weather and climate, numerical models are important tools and it is crucial that the controlling processes are described correctly. Since 70% of the global surface is covered with water the description how the ocean and atmosphere communicates has a considerable impact. LÄS MER

  4. 4. From Corals to Corporations : Social-ecological dynamics in the Anthropocene ocean

    Författare :Jean-Baptiste Jouffray; Magnus Nyström; Toby Gardner; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Anthropocene; Ocean; Coral reef; Finance; Regime shift; Sustainability; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : The ocean has always been of paramount importance for the development of human civilisation. Today more than ever, the prospect of a new era of ‘blue growth’ poses great sustainability and governance challenges as marine ecosystems worldwide face unprecedented cumulative pressures from local human impacts, global climate change and distal socioeconomic processes.

  5. 5. Modelling calving and sliding of Svalbard outlet glaciers : Spatio-temporal changes and interactions

    Författare :Dorothée Vallot; Rickard Pettersson; Veijo Pohjola; Ken Mattsson; Tómas Jóhannesson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; cryospheric science; glacier modelling; time-lapse imagery; undercutting; sliding inversion; discrete particle model; calving model; subglacial hydrology; sliding law; automatic detection method; calving events size and frequency; ocean interaction; melt water runoff; ice dynamics; ice flow model; Geovetenskap med inriktning mot naturgeografi; Earth Science with specialization in Physical Geography;

    Sammanfattning : Future sea level rise associated to global warming is one of the greatest societal and environmental challenges of tomorrow. A large part of the contribution comes from glaciers and ice sheets discharging ice and meltwater into the ocean and the recent worldwide increase is worrying. LÄS MER
