About the Isotope Ecology and Environmental Science Laboratory (ISOE2)
The Isotope Ecology and Environmental Science Laboratory studies marine, lake and river environments to improve our understanding of aquatic food webs and the environmental fate of chemicals.
We develop and apply organic molecular biomarkers and stable isotope analysis techniques to investigate complex biogeochemical carbon and nitrogen cycles in aquatic environments.
Using these methods, we study aquatic ecosystem responses to global environmental change, including climate change and pollution. We reconstruct environmental records preserved in sediments and investigate biogeochemical cycling between the water column and sediments.
1. Isotope Ecology
We use stable isotope ratios in organisms to characterize aquatic food webs and understand energy flow and trophic relationships.
Marine Nitrogen Cycling and Stable Nitrogen Isotopes
Stable Nitrogen Isotopes of Amino Acids and Trophic Position
2. Organic Carbon Cycling
Stable isotope tracer experiments and biomarker analyses of different groups of organisms help us understand biological production, energy flow and ecosystem function in aquatic environments.
Cycling of Organic Matter Produced by Phytoplankton
Marine Dissolved Organic Carbon (DOC) and Ocean Acidification (Marine Chemistry, 2016)
3. Isotope Forensics
We develop isotope-based methods to trace the effects and extent of human-induced environmental pollution on ecosystems.
Marine Nitrogen Cycling and Stable Nitrogen Isotopes
Tracing the Sources of Particulate Organic Matter in Lake Sihwa (Marine Pollution Bulletin, 2014)
4. Organic Biogeochemistry and Petroleum Organic Geochemistry
We use organic molecular biomarkers to understand environmental change, and apply organic geochemical approaches to investigate the origin, formation, accumulation and alteration of petroleum.
