Purpose
|
|
To determine sediment distribution and thickness behind Bonneville Dam. Sediment budget for Columbia River. Geologic control on benthic habitat (salmon, white sturgeon).
|
|
|
Information to be Derived
|
|
Surficial sediment distribution, sediment thickness, depth to bedrock, sediment volume, grain size
|
|
|
Summary
|
|
Completed sidescan mosaic of reservoir.
|
|
Approximately 30 km of subbottom data were collected
|
|
before Davit failed and fish was lost (but recovered 3 days later!).
|
|
Samples were collected at 21 sites,
|
|
most with good video and still photograpy.
|
|
|
Notes
|
|
Columbia River Gorge is windy, with winds greater than
|
|
40 knots, gusts up to 50. Swells ran 8-10 feet, with a period of
|
|
about 2 s. Tough place to work in a 30 foot boat. August is not
|
|
the ideal month. Expect better conditions in spring/early summer.

Got Help?
|
For E-1-01-WO, we would appreciate any information on -- contract, days at sea, dive count, funding, kms of navigation, national plan, NGDC Info, owner, project number, publications, scanned materials, seismic description, station count, station description, submersible, tabulated info.
