Senior researcher, Hydrochemistry laboratory of the Marine monitoring department

Rita Poikāne has been at LIAE Marine monitoring department since 1998. She started out as a chemist working on sea and harbour sediment research. At the moment she is responsible for planning, leading and executing local and international science projects and monitoring. Responsible for creation and maintenance of LIAE data storage system “LATMARE” and providing data to different European environmental organizations for environmental status assessments and strategic planning. Through her work on national monitoring programme and scientific research Rita Poikāne has accumulated experience and expertise in collecting, pre-treatment and preparation of water, sediment and biota samples for further analysis, quantitative analysis of nutrients and hazardous substances, including metals, in water, sediment and biota, and interpretation of results in scientific articles, monitoring and scientific grant/project reports. Rita Poikāne trains new staff in practical skills for aquatic environmental research.
