  1. 1. Modelling impact climate-related change on the thermal responses of lakes

    Author : Ana I. Ayala; Donald C. Pierson; Stéphane Goyette; Andreas Lorke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Modelling; climate change; lakes; thermal structure; surface heat fluxes; extreme events;

    Abstract : In response to climate-related changes, lakes worldwide have experienced warmer surface water temperatures, shorter ice cover periods and changes in lake stratification. As these aspects of lake dynamics exert substantial control over nutrient availability, oxygenation and biogeochemical cycling, predicting changes in lake water temperature and stratification dynamics can improve our understanding of the consequences of warming on lake ecosystems.

  2. 2. Climate Effects on Phytoplankton Biomass and Functional Groups

    Author : Hampus Markensten; Donald Pierson; Kurt Pettersson; Bengt Boström; Colin Reynolds; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; Climate change; phytoplankton; chlorophyll a; Lake Mälaren; Galten; PROTBAS; numerical modeling; water quality; succession; shallow lake; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Future climate in temperate regions is projected to get warmer and in many cases wetter. This poses questions about how phytoplankton in our lakes will respond. READ MORE

  3. 3. Climate Change Impacts on the Catchment Contribution to Lake Water Quantity and Quality

    Author : Karen Moore; Kurt Pettersson; Donald Pierson; Timothy Kratz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; water quality modelling; Lake Mälaren; GWLF; nutrient transport;

    Abstract : A key question related to climate change projections is how will aquatic systems respond to changes in variables such as temperature and precipitation? This thesis uses GWLF, a simple catchment scale model to explore potential impacts of climate change on water quantity and quality.River discharge and nutrient loads were modelled for several warmer world scenarios.
