  2. 1. Some Concepts of Estuarine Modeling

    Author : Bror Jönsson; Peter Lundberg; Kristofer Döös; Björn Kjärfve; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oceanography Modeling Estuaries; Meteorology; Meteorologi;

    Abstract : If an estuarine system is to be investigated using an oceanographic modeling approach, a decision must be made whether to use a simple and robust framework based on e.g. mass-balance considerations, or if a more advanced process-resolving three-dimensional (3-D) numerical model are necessary.

  4. 2. Importance of bacterial maintenance respiration and baseline respiration for development of coastal hypoxia

    Author : Kevin Vikström; Johan Wikner; Jan Karlsson; Josep M. Gasol; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Respiration; Estuarine; Allochthonous; Maintenance; primary production; bacterial production;

    Abstract : Reduced oxygen concentrations and increasing hypoxic zones havebecome more common in the sea due to climate change andeutrophication. The main cause of oxygen loss in oxygenatedenvironments is respiration. READ MORE

  5. 3. Fate of riverine iron over estuarine salinity gradients

    Author : Simon Herzog; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; iron Fe ; Organic matter; boreal rivers; XAS; DLS; Fe isotope;

    Abstract : Rivers have traditionally not been considered important sources of bioavailable iron (Fe) to the marine waters, since most Fe is lost by salinity-induced aggregation and sedimentation during estuarine mixing. However, recent studies from boreal rivers found a remarkably high Fe stability, probably due to the interaction with organic matter. READ MORE

  6. 4. Deltaic to estuarine deposition : process regime changes and products

    Author : Anna Pontén; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : .... READ MORE

  7. 5. Carbon and nitrogen fluxes associated to marine and estuarine phytoplankton

    Author : Malin Olofsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nutrient assimilation Stable isotopes Single cell diversity Phytoplankton;

    Abstract : Globally, mainly nitrogen or phosphorus is limiting the primary production. New nitrogen can enter estuarine ecosystems as nitrate from upwelling events, from river runoff, atmospheric deposition, or by nitrogen fixation. READ MORE
