DESCRIPTION:Rapid Arctic warming and permafrost thaw are exposing previousl
 y frozen minerals and sediments to chemical weathering\, with important im
 plications for river chemistryand the global carbon cycle. In this talk\, 
 I use sulfur and oxygen isotopes together with multi-decadal river chemist
 ry records from northeast Greenland to investigate howweathering processes
  have changed over time and react strongly to erosion and extreme rainfall
  events. Particular attention is given to sulfide oxidation and its intera
 ction withcarbonate minerals\, revealing how hydrological changes in perma
 frost landscapes canalter river chemistry and potentially influence atmosp
 heric CO₂ fluxes.
