  2. 11. 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. 12. Marine biogenic polysaccharides as a potential source of aerosol in the high Arctic : Towards a link between marine biology and cloud formation

    Author : Qiuju Gao; Caroline Leck; Ulrika Nilsson; Eric Saltzman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polysaccharides; Biogenic polymer microgels; Arctic Ocean; LC MS MS; Surface microlayer; Marine aerosol particles; Remote marine cloud condensation nuclei; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Primary marine aerosol particles containing biogenic polymer microgels play a potential role for cloud formation in the pristine high Arctic summer. One of the major sources of the polymer gels in Arctic aerosol was suggested to be the surface water and more specifically, the surface microlayer (SML) of the open leads within the perennial sea ice as a result of bubble bursting at the air-sea interface.

  5. 13. Eel migration - results from tagging studies with relevance to management

    Author : Niklas B. Sjöberg; Sture Hansson; Håkan Wickström; Erik Petersson; Alan Walker; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anguilla anguilla; Migration; Stocking; Marking; Anguillicola crassus; Data storage tags; Carlin tagging; Strontium; Survival analysis; Dormancy; Lake Mälaren; Baltic Sea; Atlantic Ocean; Sargasso Sea; Marine Ecology; marin ekologi;

    Abstract : In response to the drastic decline of the European eel (Anguilla anguilla (L.)) fisheries have been reduced and elvers are stocked in areas where natural abundances are low. READ MORE

  6. 14. Changes in ocean geochemistry across the K-Pg boundary interval

    Author : Tjördis Störling; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; K-Pg boundary; Paleocene; stable silicon isotopes; sponge spicules; radiolaria; Cerithium Limestone;

    Abstract : The Cretaceous - Paleogene boundary (K-Pg, 66 Ma) was a time interval with dramatic changes in the Earth’s climate and the ocean environment. It was characterized by severe disruptions of marine biogeochemical cycles due to a meteorite impact during a time of active volcanism. READ MORE

  7. 15. Bacterioplankton in the light of seasonality and environmental drivers

    Author : Carina Bunse; Jarone Pinhassi; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine bacteria; marine microbiology; seasonal succession; ocean acidification; proteorhodopsin; photoheterotrophy; microbial time series; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology; Miljövetenskap; Environmental Science;

    Abstract : Bacterioplankton are keystone organisms in marine ecosystems. They are important for element cycles, by transforming dissolved organic carbon and other nutrients. Bacterioplankton community composition and productivity rates change in surface waters over spatial and temporal scales. READ MORE
