Natural Organic matter (OM) is globally ubiquitous and a keystone interactive medium in environmental ecosystem functioning. The vast molecular diversity of natural OM may be both a symptom or a cause of its mediating role in various processes essential for life on Earth, such as nutrient retention and resupply, or climate stability. Dissolved organic matter (DOM) forms the main carbon and energy source for microbial life, still it accumulates in the oceans to one of the biggest carbon reservoirs on Earth. Pyrogenic organic matter (PyOM) is an important component of OM and is characterized by its condensed aromatic composition. It originates from natural (e.g., wildfires) and anthropogenic sources (e.g., biochar) and despite the importance of PyOM in the environment, its processing and fate remain largely unknown.
In this session, we aim to bring together the latest insights into the partitioning and size of all reservoirs of the global carbon cycle and the processes governing fluxes of carbon between these reservoirs. We invite contributions from process- to field-scale approaches and method development for a detailed understanding of isotopic and molecular composition of individual carbon reservoirs, as well as their active role within ecosystem functioning. We are interested in studies showing new field data, laboratory experiments and modeling that use geochemical tracers (e.g., 14C, biomarkers, stable and non-traditional isotopes, trace elements) combined with geomorphic and hydrological tools to unravel controls on the carbon cycle from the local to the global scale. Modern analytical tools and their combination are crucial in advancing this research field, encompassing a variety of spectroscopic and mass spectrometric techniques (AMS, NIR, MIR, NMR, XPS, py-GC-MS, HR-MS, LC-MS-MS, EEMs-PARAFAC, PTR-MS, etc.) as well as new computational approaches.
