Terrestrial cosmogenic nuclides (TCNs) have become a standard tool within the Earth Sciences for dating geomorphological events and for quantifying rates of surface processes over a wide range of spatial and temporal scales. Long-standing questions of glacial geomorphology and landscape development have been addressed, principally through the use of in-situ 10Be and 26Al. The last decade has also seen the refinement of analysis and interpretation of hitherto less commonly-used isotopes, 3He, 21Ne and 36Cl. More recently new applications of TCNs have flourished alongside innovative sampling strategies and advances in sample chemistry and measurement. Work is also being carried out on new isotopes such as 14C and 53Mn.

This session invites contributions that consider both novel applications of TCNs and the methodological development of the technique. We particularly encourage studies that: (1) focus on the development and/or applications of new isotopes, such as 14C and 53Mn; (2) develop more complex interpretative strategies that extend the application of TCNs beyond dating events and determining process rates; (3) combine geo-chronometers in order to integrate across different temporal scales and/or use cosmogenic 3He and 21Ne to quantify palaeo-denudation rates; and (4) use TCNs to constrain surface process models at all scales.
