Presentation Transcript

  1. Tracing dust provenance and paleoclimate in the Wasatch Mountains using strontium isotopes Olivia Miller

  2. Previous work Sr ratio in soil water taken up by the trees moves towards that of water (.71). (Goran, 1994) (Groussetand Biscaye, 2005)

  3. Dust landing on snow • Earlier melt and less runoff • Dust increases with drought and soil disturbance Black = observed Purple = modeled without dust ~85% of SLC water comes snowmelt water

  4. Deficiencies my study will address Where is the dust coming from? Can we see the dust record in tree rings? Is the dust source changing over time?
