  1. 6. Evolutionary and Ecological Effects of Metal Pollution on Coastal Diatoms

    Författare :Björn Andersson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton; Diatoms; Skeletonema marinoi; Toxicity; Heavy metals; Copper; Evolution; Baltic Sea; Population genomics; Physiology; Ecology; Metabarcoding; Sedimentology; Resting stages; Dose-response relationships;

    Sammanfattning : Oceans are changing rapidly in response to human activities, such as toxic pollution, eutrophication, and climate change. Diatoms are major primary producers in the oceans with short generation times, flexible reproductive strategies, and high standing genetic diversity. LÄS MER

  3. 7. Numerical Model of Beach Topography Evolution due to Waves and Currents: Special Emphasis on Coastal Structures

    Författare :Thanh Nam Pham; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; morphodynamics; surface roller; wave-induced currents; random waves; sediment transport; coastal structures;

    Sammanfattning : The beach topography change in the nearshore zone may be induced by natural phenomena such as wind, wave, storm, tsunami, and sea level rise. However, it can also be caused by man-made structures and activities, for example, groins, detached breakwaters, seawalls, dredging, and beach nourishment. LÄS MER

  4. 8. Simulations of Coastal Atmospheric Dynamics and Transport Processes

    Författare :Ragothaman Sundararajan; Dimitris Melas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; coastal atmosphere; dynamics; transport; Lagrangian particle dispersion model; mesoscale model; turbulence; Geovetenskap; Earth sciences; Geovetenskap; Meteorology; meteorologi;

    Sammanfattning : The marine atmosphere can be highly variable in space and time, and the coastal terrain plays a crucial role in influencing its properties. These, in turn, determine the atmospheric transport in the coastal zone. LÄS MER

  5. 9. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments

    Författare :Elias Broman; Mark Dopson; Nils Risgaard-Petersen; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; sediment; oxygen; metatranscriptomics; metagenomics; 16S rRNA gene; RNA-seq; dead zone; re-oxygenation; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. LÄS MER

  7. 10. Geomorphology and environmental dynamics in Save River delta, Mozambique : A cross-timescale perspective

    Författare :Elidio Massuanganhe; Lars-Ove Westerberg; Robert Marchant; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Save River delta; deltaic wetlands; biogeomorphology; climate change; landscape evolution; coastal management; socio-ecological systems; Physical Geography; naturgeografi;

    Sammanfattning : Long-term perspectives on the evolution of river deltas have provided useful knowledge capable of responding to pending questions related to the ongoing climate and environmental changes. Increasing utilization pressure on delta environments has necessitated increased attention to protect the socio-economic and ecological values. LÄS MER
