Expression of benthic isotope effects associated with nitrogen elimination and regeneration in lacustrine sediments

01.10.2020 – 30.09.2024

Summary

Scientific abstract

In many ocean regions, as a limiting nutrient, bioavailable nitrogen (N) controls marine primary productivity and thus the ocean’s capacity to fix and sequester atmospheric CO2 in its interior. In many lakes, N from both natural and anthropogenic sources is an important driver of lacustrine eutrophication. Therefore, both in the ocean and in lakes, it is crucial to understand the sources and sinks of fixed N. Denitrificatio...
