Stable Isotope Ratios of Nonexchangeable H in Organic Matter
Lake carbon sources are a mix of different proportions of terrestrial plants and internally produced organic matter. Attributing source contribution in lakes of carbon pools and fluxes is essential for understanding how they work or how they respond to climate change. The organic matter produced by terrestrial plants has a very different isotopic signature compared to algae growing in lakes. Stable Isotope Ratios of Nonexchangeable H is a promising novel tool that is able to attribute the relative sources and contributions to aquatic ecosystems However, measurements are still difficult to carry out and availability is limited. My work over the last years has been to develop sample preparation and analysis. I have built new equipment for offline sample preparation, optimized sample treatment procedure and carried out experiments to understand critical aspects for these analyses.
