Stability Of Basin-Scale Internal Waves Within The South Arm Of The Great Salt Lake, Joshua David Soelberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The fluid circulation patterns, temperature distributions, and density gradients of the South Arm of the Great Salt Lake were modeled using the Estuary, Lake, and Coastal Ocean Model (ELCOM) from the Centre for Water Research at the University of Western Australia. The effort is part of a research study in conjunction with the United States Geological Survey (USGS) and the Utah Water Research Lab located at Utah State University. The model was simulated for several different cases of salinity gradients over different time periods, using temperature and wind data from 2006. The model is then used to identify factors which …

Effects Of Heavy Metals (Cadmium, Copper, And Mercury) On Reproduction, Growth, And Survival Of Brine Shrimp (Artemia Salina) From The Great Salt Lake, Karl A. Gebhardt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to report findings concerning the effects of cadmium, copper, and mercury on the brine shrimp Artemia Salina, of the Great Salt Lake. Metal toxicity was observed in relation to acute susceptibility, growth, reproduction, and hatching of the brine shrimp.

Heavy metal concentrations such as cadmium, copper, and mercury are known to be considerably higher in the Great Salt Lake than those in both freshwater and seawater. No published study has been concerned with heavy metal effects on organisms in salinities greater than seawater (35 grams per liter total dissolved solids). The experiments reported …
