These watergun signatures were collected by Alan Mix (OSU), Chief Scientist, and Steve Bloomer (UNB) during Leg 3 of the GENESIS Expedition in spring 1997 aboard the R/V Roger Revelle. Seth Mogk (SIO) was the Geophysical Engineer. The ship was stationary and a modified sonobuoy hydrophone was lowered over the side. A single 80cu.in. SSI watergun was fired at different depths. The data were recorded on the "HIG" Sun A/D and decimated to a 1/4 mil sample interval. No filters were used. The data are located in /sam1/mcs/1997/gene03rr.SIOSEIS plot of shots 101 - 110.
