Juris Aigars

Juris Aigars serves as Director of an institute and holds the position of Assistant Professor at the University of Latvia. His primary research focus centers on biogeochemical cycles within the Baltic Sea ecosystem, specifically examining the circulation of biogenic elements, pollutants, and microplastics under changing climatic and anthropogenic pressures. His work critically assesses the Baltic Sea's capacity to deliver ecosystem services amidst these environmental stressors.

Research interests span marine ecology, biogeochemistry, and environmental pollution with emphasis on

• Microplastic distribution and chemical composition in Baltic surface waters
• Trophic transfer of contaminants like mercury in fish populations
• Seasonal dynamics of nutrient cycles and phytoplankton assemblages
• Climate change impacts on marine ecosystem services
• Methodological development for pollution monitoring

His publication record demonstrates consistent focus on Baltic Sea processes, particularly in the Gulf of Riga, with recent work expanding into microplastic pollution and cumulative impact assessment for maritime spatial planning.

Scientific contributions include collaborative projects such as

• Detect2Protect: New approaches for chemical pollution impact assessment
• LIFE REEF: Ecosystem service-focused marine research
• Maritime spatial planning tool development for Baltic policy implementation

His work bridges empirical field studies with policy-relevant applications for Baltic Sea management.

Professional engagement includes leadership in the institute where he directs research initiatives while maintaining active publication output. Current projects address microplastic pollution baselines, contaminant trophic magnification, and ecosystem service valuation for marine protected areas. His research group collaborates extensively across Baltic institutions to tackle regional environmental challenges through integrated approaches combining chemistry, ecology, and policy analysis.
