This session is open to all contributions in biogeochemistry and ecology where stable isotope techniques are used as analytical tools, with foci both on stable isotopes of light elements (C, H, O, N, S, …) and new systems (clumped and metal isotopes). We welcome studies from both terrestrial and marine, aquatic and sedimentary environments as well as methodological, experimental and theoretical studies that introduce new approaches or techniques (including natural abundance work, labeling studies, modeling). Results from the successful EGU session that took place earlier have been published in several special issues of Organic Geochemistry and Isotopes in Environmental & Health Studies.
Stable isotope signatures provide unique tools to identify, quantify, and predict biogeochemical element cycling through and across boundaries of all geo spheres, and on extremly different scale dimensions. Mechanistic approaches, however, require careful approaches wrt. analytical methods, standardization, experimental verification, and theoretical evaluation. Stay tuned for the latest achievements in the field of stable isotope biogeosciences.
