Chicago Sanitary and Ship Canal near Lemont, Illinois Geophone Data

The study at Lemont replicated and expanded upon seismic data collected at that location in 2011 as well as evaluated the pressure field created in the water by the water gun. The replicate data were collected with the water gun placements and input pressure identical to the 2011 study, but added static underwater pressure monitoring. Two 80-in³ water guns were suspended below a platform at depths of 4 and 14 feet. Pressure values were lower when only the gun suspended at 4 feet was fired as compared to firing the single gun at 14 feet and both guns simultaneously, with the latter two producing similar pressures. Data were collected to assess the pressure field produced by two 80-in³ water guns suspended at a depth of 14 feet, but [...]
