  2. 16. 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

    Author : Dmytro Kyryliuk; Susanne Kratzer; Steve W. Lyon; Michelle McCrackin; Koponen Sampsa; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean Colour; MERIS; OLCI; water quality; marine ecology; coastal areas; Baltic Sea; Marine Ecology; marin ekologi;

    Abstract : 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. READ MORE

  4. 17. Causal links of past climate change in Coupled Model Intercomparison Project Phase 5 climate models

    Author : Thanh Le; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; solar forcing; volcanic forcing; greenhouse gases radiative forcing; Granger causality; near-surface air temperature; ENSO; IOD; CMIP5; North Atlantic;

    Abstract : The climate system is influenced by various external forcings (e.g. volcanic forcing, solar forcing and change of greenhouse gas concentrations) and its own internal climate variability. READ MORE

  5. 18. Identifying Global Patterns of International Fisheries Conflict

    Author : Jessica Spijkers; Henrik Österblom; Tiffany Morrison; Maarten Bavnick; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; conflict; fisheries;

    Abstract : International conflict over fishery resources is becoming a growing security concern. As both incidences of conflict as well as their environmental drivers are expected to increase, the international community has become increasingly wary of this potential future security threat.

  6. 19. Structural changes in marine ecosystems – the application of novel network approaches to understand marine regime shift

    Author : Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Anthropogenic drivers, such as climate change and fishing, have severe, often unexpected impacts on marine ecosystems. Species responses to drivers may have cascading effects through ecological communities, potentially changing the structure and functioning of the food web. READ MORE

  7. 20. Carbon and nitrogen dynamics in agricultural soils : model applications at different scales in time and space

    Author : Thord Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : An understanding of soil organic carbon (C) and nitrogen (N) dynamics is essential for efficient and environmentally sustainable agricultural production. This thesis includes model studies of C mineralization at regional/national level with annual time steps, N balances at field level with annual time steps, and N dynamics at 34 locations within a single field with daily time steps.
