   Författare :Jan Mikael Malmaeus; Lars Håkanson; Kurt Pettersson; Jürg Bloesch; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; mass balance model; dynamic model; mechanistic model; phosphorus; LEEDS; suspended particulate matter; settling velocity; sedimentation; accumulation sediments; burial; diffusion; climate scenario; Erken; Balaton; Kinneret; Batorino; Miastro; Naroch; Galten; Ekoln; Geovetenskap; Earth sciences; Geovetenskap;

   Sammanfattning : This thesis presents predictive models for important variables concerning eutrophication effects in lakes. The keystone is a dynamic phosphorus model based on ordinary differential equations. LÄS MER

3. 2. Phytoplankton and Physical Disturbance : Seasonal dynamics in temperate Lake Erken, Sweden

   Författare :Yang Yang; Kurt Pettersson; Peeter Nõges; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton dynamics; high-frequency measurements; thermal stratification; water column stability; equilibrium; disturbance;

   Sammanfattning : Phytoplankton mirrors changes in the environment and plays an important role in biogeochemical processes. Phytoplankton dynamics is the outcome of both autogenic succession and external disturbances. LÄS MER
