Deep-Water Near-Bottom Turbulence In Lake Michigan: An Underwater Investigation, David J. Cannon, Cary Troy
Deep-Water Near-Bottom Turbulence In Lake Michigan: An Underwater Investigation, David J. Cannon, Cary Troy
The Summer Undergraduate Research Fellowship (SURF) Symposium
Motivated by a need to characterize near-bottom deep-water turbulence for an understanding of the filtration capabilities of invasive quagga mussels, an instrument tripod was deployed in Lake Michigan for six months in 60m of water to measure current velocities, with specific interest being paid to near-bottom (0.10 to 0.95 meters above bottom) velocities during the deployment. The deployment period (September 2012-April 2013) was characterized by very little stratification and a median temperature of about throughout the water column. A mean horizontal velocity of 3.6 cm/s with a standard deviation of 2 cm/s was also measured at 1 meter above the …

Project Background
• Many rural areas on the planet do not have easy access to clean water!
• Water distillation basins are capable of distilling water by using incident solar radiation to evaporate polluted water.
• Current thermodynamic models used to predict behavior require instantaneous data; requires the use of expensive equipment.
• Distillation basins are dependent on multiple meteorological variables: insolation, temperature, wind speed, cloud cover.
• Non‐linear behavior is difficult to predict for long term operations.

Endocrine-disrupting compounds (EDCs), such as estrogen, are known to be present in the aquatic environment at concentrations that affect fish and other wildlife. For example, juvenile male fish exposed to estrogen will synthesize vitellogenin, which is a female-specific protein. Estrogen exposure is also linked to sex reversal, intersexuality, and inhibition of gonadal growth (Jobling et al., 1996).
Wastewater treatment plants are major contributors of EDCs into the environment. EDCs end up in wastewater as a result of natural excretion from the body or being washed off the skin. WWTPs are not designed to remove these substances. As a result, EDCs …
