Modeling Sound Propagation in the Great Salt Lake
One candidate for dark matter are quark nuggets. One experiment to find quark nuggets is to detect acoustical waves generated by quark nuggets as they pass through large bodies of water. We are studying the possibility of detecting acoustical waves radiating from quark nuggets in the Great Salt Lake, chosen due to its lack of marine life and human activity. Acoustical measurements of explosions in the lake are taken as a model for quark nugget impacts. Various acoustical properties of the Great Salt Lake, like sound speed, density, and coefficient of attenuation, are used in a range-independent propagation model to calculate the transmission loss (transfer function) in the lake. Given the high salinity and shallow depth, the estimated transmission loss is large. We estimate a 3 km radius over which it would be possible to detect quark nuggets passing through the lake.
