  2. 1. Late Weichselian and early Holocene shore displacement in the central Baltic, based on stratigraphical and morphological records from eastern Småland and Gotland, Sweden

    Author : Nils-Olof Svensson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pollen; Paleontologi; Shore displacement; Land uplift; Paleobotanic;

    Abstract : The glacial unloading and resulting isostatic land uplift have together with hydro-isostasy, eustatic rise of sea-level and geoidal changes, ruled the shore displacement of Fennoscandia. Within the Baltic basin, periods of damming and shifts of outlet further complicated the shore displacement during the period studied, c. 12,200-8400 BP. READ MORE

  4. 2. Benthic fluxes of biogenic elements in the Baltic Sea : Influence of oxygen and macrofauna

    Author : Nils Ekeroth; Sven Blomqvist; Per OJ Hall; Bjørn Sundby; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sediment biogeochemistry; Bioturbation; Benthic nutrient fluxes; Bottom water oxygenation; Box corer; Sediment sampling; Marine Ecology; marin ekologi;

    Abstract : This thesis investigates how benthic fluxes of phosphorus (P), nitrogen (N), and silicon (Si) change upon oxygenation of anoxic soft bottoms in the brackish, eutrophicated Baltic Sea. Direct measurements in situ by benthic landers demonstrated that fluxes of dissolved inorganic P (DIP) from anoxic bottom sediments in the Eastern Gotland Basin are higher than previously thought (Paper I).

  5. 3. On benthic fluxes of phosphorus in the Baltic Sea proper – drivers and estimates

    Author : Nils Ekeroth; Sven Blomqvist; Per Hall; Volker Brüchert; Brita Sundelin; Jonas Gunnarsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine Ecology; marin ekologi;

    Abstract : This Thesis focuses on the exchange of phosphorus (P) across the sediment–water interface in the Baltic Sea proper, with particular attention to the influence of bioturbating macrofauna and benthic redox conditions. Benthic P fluxes have major influence on P availability in the water column, which in turn regulates growth conditions for dinitrogen fixating cyanobacteria in the Baltic proper. READ MORE

  6. 4. Modelling the Dissolved Inorganic Carbon System in the Baltic Sea

    Author : Moa Edman; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Kattegat; pH; pCO2; total alkalinity; biogeochemistry; dissolved inorganic carbon; eutrophication; acidification; climate change; numerical modelling;

    Abstract : Oceans are capable of storing part of the emitted anthropogenic carbon dioxide (CO2) due to the formation of carbonic acid and subsequent dissociation. CO2 is also assimilated by biota and the inorganic carbon system is thus coupled to biogeochemical processes. READ MORE

  7. 5. Physical control of phytoplankton growth in the Baltic Sea : a multitude of spatio-temporal scales

    Author : Sulev Nõmmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fytoplankton;

    Abstract : Shipboard systems have been used for concurrent quasi-continuous measurements ofparticle size distribution, Chi fluorescence, salt and temperature and meteorologicalparameters. A resolution from 100 m to basin-wide, supplemented with variousmeasurements at fixed stations made it possible to investigate biological- physical couplingsduring the vernal phytoplankton bloom of the two years 1985/86 and in a coastal area ofthe Baltic Sea.
