  4. 23. Applications of ocean transport modelling

    Författare :Hanna Corell; Kristofer Döös; Björn Kjerfve; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean transport modelling; connectivity; particle-tracking; sediment transport; Forsmark; marine protected areas; MPA; stream functions; heat flux; wind forcing; Carcinus maenas; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The advective motion of seawater governs the transport of almost everything, animate or inanimate, present in the ocean and those lacking the ability to outswim the currents have to follow the flow. This makes modelling of advective ocean transports a powerful tool in various fields of science where a displacement of something over time is studied. LÄS MER

  5. 24. Studies on Baltic Sea mysids

    Författare :Martin Ogonowski; Sture Hansson; Jörgen Berge; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mysids; hydroacoustics; Baltic Sea; abundance; stable isotopes; specific dynamic action SDA ; diel vertical migration; partial migration; trophic interactions; physiology; benthic-pelagic coupling; protein:DNA; C:N ratio; genetic structure; Marine Ecology; marin ekologi;

    Sammanfattning : Mysid shrimps (Mysidacea, Crustacea) are efficient zooplanktivores in both marine and freshwater systems as well as lipid rich prey for many species of fish.  Although some efforts have been made to study the role of mysids in the Baltic Sea, very few studies have been carried out in recent time and there are still knowledge gaps regarding various aspects of mysid ecology.
