Purpose
|
|
Identify the landslide and earthquake hazards as well as related ground deformation processes that have great potential to impact the social and economic well being of the inhabitants of the Southern California coastal region.
|
|
|
Information to be Derived
|
|
High-resolution multichannel (MCS) and Huntec seismic-reflection profiles to image the faults and to use dating of sediment -core samples to establish timing and rates of movement on the faults.
|
|
|
Summary
|
|
Continue surveying (the second of four planned data collection cruises)
|
|
the coastal zone between Santa Monica and San Diego; MCS and Huntec data
|
|
will be used to identify the active faults in the nearshore zone and to
|
|
assess the seismic hazards expected.
|
|
|
Notes
|
|
Lines with tags a, b, c, etc. are all planned lines.
|
|
a, b, etc. were added to the full line name
|
|
when something in the lab changed during the line
|
|
(i.e., for mcs, the blue screen of death or some other problem,
|
|
or for huntec, if the paper ran out or the recording disks ran out).
|
|
a and b indicators were used independently for mcs and huntec,
|
|
so they will can not be correlated between the two systems.
|
|
|
|
Once or twice we did the a planned line in two segments on different days
|
|
(I think 247,247a or 245,245a is one time this happened),
|
|
but this will show up on with the time indicators.
|
|
|
|
The tags "dl" or "dm" mean dog legs, between planned lines.
|
|
MCS may have been on during this time, but probably were not recorded.
|
|
"dm" was used as a,b was noted above.
|
|
|
|
99l: planned line on the 085 degree or 040 degree trends
|
|
(I'm not sure of the actual orientation of the lines, so don't quote me.)
|
|
In general (but not every time) MCS was on for these.
|
|
There are a couple of exceptions.
|
|
|
|
99n: Huntec-only lines run at night in any orientation.

Got Help?
|
For O-1-99-SC, we would appreciate any information on -- contract, days at sea, dive count, funding, kms of navigation, NGDC Info, organization, owner, project number, scanned materials, seismic description, station count, station description, submersible, tabulated info.
