Kari Austnes holds an MSc in environmental chemistry and a PhD in biogeochemistry. Her research deals with biogeochemical processes and how catchment processes affect water quality. The research is particularly focused on dissolved organic matter (DOM), acidification and nutrient transport. The effects of climate change on the biogeochemical processes are central to the research. The methodological approaches range from lab and field experiments to analysis of long-term data series and big regional data sets. She has experience in catchment modelling, and the use of sensor technology in monitoring has become a central part of her work in the last few years. The projects range from basic research via applied research to monitoring and assessments for the environmental management. She has been project leader for the national RID programme (Riverine and Direct Discharges), and has several projects for the environmental management authorities related to acidification – liming, critical loads and classification under the Water Framework Directive. She also works for the European Environment Agency through the European Topic Centre on Inland, Coastal and Marine waters, where she is involved in the assessment of the ecological status and nutrient conditions of European lakes and rivers, and evaluations of the effects of climate change on freshwaters.
