We investigate the effect of weathering and erosion of fossil organic carbon, which is eroded today in eastern Nepal at the upstream Kali Gandaki river. This carbon was removed from the atmosphere through photosynthesis millions of years ago and is exported today by this river. We are developing novel methods to characterize this organic carbon on a molecular level (compound-specific carbon and hydrogen isotope analysis, ultra-high resolution mass spectrometry FT-ICR-MS) and better understand transport and transformation.
