How to obtain and preserve high quality isotope data

This multidisciplinary session invites contributions interested to obtain and preserve high quality of isotope data used in many scientific fields (biogeosciences, hydrology, climate reconstructions, atmospheric observations, environment, ecology, forensics). Number of studies using natural stable and radioisotopes - and the amount of data - is enormously increasing last years, and a high concern is attributed to the data quality and compatibility. Isotopic tools are becoming a common technique, but large datasets are still difficult to compare / combine as the data quality is often unknown or inconsistent due to: (i) different sampling and analytical protocols, (ii) deviations in calibration approaches, origin and quality of reference materials, (iii) improper sample manipulation and preparation; (iv) different methods of data corrections, normalizations and processing protocols, etc. All that may bring, and often do, to large unrecognised biases.
The problems and approaches in use are very similar, despite of different fields and isotope systems in use.

The session calls for papers focused on the detection of flaws with special attention to uncertainty estimation, creating protocols (SOPs) and tools for self-assessment of Quality Assurance/Quality Control (QA/QC), proper use of materials for normalization and exploring future trainings needs. This session is a plea for approaches and tools for high quality isotope data to be applied in many sciences and cross-disciplinary. High quality isotope data are required not only in contemporary studies, but also shall be preserved for the future, in order to better understand environmental and climatic changes.
