The Effect of the Shrinking Great Salt Lake on Snow Duration in The
University of Utah UNDERGRADUATE RESEARCH JOURNAL Blowing in the wind: The effect of the shrinking Great Salt Lake on snow duration in the Wasatch Mountains. Chase Hodges-Heilmann (Gannet Hallar, Tanner Visnick, Christopher Rapp) Department of Atmospheric Science Introduction Utah has two things that tourists know about, the Great Salt Lake, and the Greatest Snow on Earth. The Great Salt Lake is receding and impacting the seasonal duration of the Greatest Snow on Earth. As the Great Salt Lake shrinks, the more arid surface contributes to more windblown dust. When this dust deposits onto snow, the albedo of the surface is decreased, and thus snow melts quicker. Relevant Literature Health complications, issues with visibility, and climate change are all influenced by windblown dust. Dust from the Great Salt Lake accounts for a total of 7% of all wind-blown dust in the Wasatch mountains (Skiles et al., 2018). Lake Sevier and the Great Salt Lake Desert make up the majority of wind-blown dust on the Wasatch mountains (Hahnenberger and Nicolli, 2012). Although dust from the Great Salt Lake right now isn’t major, the lakebed of the Great Salt Lake is becoming more and more exposed. Since pioneers arrived to Salt Lake City in 1847 the Great Salt Lake has decreased in elevation by 11 feet, which translates to a volume reduction of 48% and exposing nearly half of the lake bed (Wurtsbaugh et al., 2016). A decrease in volume of saline lakes is often attributed to global warming and climate change, but water development and diverting tributaries is also to blame (Wurtsbaugh et al., 2017). -

It has a red bill, blue-grey crown, pink chin, throat and foreneck, prominent yellow-green shoulder patches, bluish rump and back, and blue-green uppertail. Distribution This species has a patchy and irregular distribution in arid Australia. In the Northern Territory, it occurs in the southern section of the Tanami Desert south to Angas Downs and Yulara and east to Alice Springs. The exact distribution within this range is not well understood and it is unclear whether the species is resident in the Northern Territory. Few locations exist in the Northern Territory where the species is regularly seen, and even Known locations of the princess parrot. then there may be long intervals (up to 20 years) between records.

External Editor: Prasad S. Thenkabail Received: 16 June 2014; in revised form: 5 September 2014 / Accepted: 9 September 2014 / Published: 29 September 2014 Abstract: The spatial extent of desertified vs. rehabilitated areas in the Mu Us Sandy Land, China, was explored. The area is characterized by complex landscape changes that were caused by different drivers, either natural or anthropogenic, interacting with each other, and resulting in multiple consequences. Two biophysical variables, NDVI, positively correlated with vegetation cover, and albedo, positively correlated with cover of exposed sands, were computed from a time series of merged NOAA-AVHRR and MODIS images (1981 to 2010).
