This example was shot by Sherm Bloomer (OSU), Chief Scientist, Dawn
Wright (OSU), and Dave Tappin (BGS) during BOOMERANG Expedition
Leg 8 aboard the R/V Melville in May/Jun 1996. Seth Mogk (SIO) was
the Geophysical Engineer.
A single SSI 80 cubic inch watergun was used for the source. Only one
channel of a two channel "high speed" streamer is used in the plots
below. The data were recorded with the HIG Sun A/D at 1kHz (1 mil).
No recording filters were used. The shot interval was 10 seconds
while the ship progressed at 6 knots.
The plot was produced by the following SIOSEIS script:
