Tracing dust provenance and paleoclimate in the Wasatch Mountains using strontium isotopes
Olivia Miller
Previous work
(Grousset and Biscaye, 2005) (Goran, 1994)
Sr ratio in soil water taken up by the trees moves towards that of water (.71).
Dust landing on snow
Black = observedPurple = modeled without dust
• Earlier melt and less runoff• Dust increases with drought and soil
disturbance
~85% of SLC water comes snowmelt water
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?
