Research in the Tzortziou Land-Ocean-Atmosphere Interactions laboratory focuses on assessing impacts of anthropogenic pressures and environmental hazards on inland, coastal, and open ocean biogeochemical cycles, ecological processes, and ecosystem services across temporal and spatial scales. Specific environmental stressors addressed in ongoing projects include urban development, human population shifts, atmospheric pollution, eutrophication, global warming, sea level rise, permafrost thawing, and changing hydrological regimes. Research in the Tzortziou laboratory applies an interdisciplinary framework that integrates enhanced ground-based and satellite remote sensing bio-optical tools with new coupled atmospheric-hydrodynamic-photo-biogeochemical models. Partnering with relevant stakeholders, a key objective of our research is applying results to link science to practice and enhance decision support systems.
