Cruise Summary Notes (modified from 5/27/94 USGS Bulletin)
Recently returning from the Colorado River, Roberto Anima, Mike Marlow, Dave
Hogg, and Kaye Kinoshita report that wind, rain, hail, and heat, were
encountered during an extremely successful geophysical data collection cruise.
The team collected digitized high-resolution geophysics and side-scanning sonar;
fathometer, and underwater video to measure the extent of sediment stored along
fourteen reaches of the Colorado River corridor.
The project is part of the Grand Canyon Environmental Study (GCES) that is
investigating the effects of fluctuating river discharge (controlled by Glenn
Canyon Dam) on the river's ecosystem.
USGS's involvement is to look at the sediment supply along the corridor.
The initial results of the survey revealed that approximately 3 to 9 meters of
sediment cover bedrock or talus along many of the reaches, and that the amount
of talus in the river, from the margins, greatly effects the amount of sediment
cover.
Dave Hogg, Fred Paine, Mike Boyle and the rest of the ET shop did an outstanding
job of preparing all the electronics and boxing the equipment for the wet and
bumpy conditions encountered in the rapids.
Only two very minor wiring problems occurred during the 21 days of surveying.
