EBD at Garner Valley, CA Aug 15-21 2004
Background
Garner Valley has been monitored for about 15 years by UCSB, due to its
fault proximity and alluvial soil. It presents a nice opportunity to
instrument basin soil conditions similar to those in many populous
cities. For this collaborative experiment, the T-Rex shaker truck from
UT was used to shake the earth at 18 sites throughout the valley,
while the USGS and UCSB people measured the results with local and
distributed sensors. Secondary efforts included the CENS
self-organizing wireless sensor networks, a grand opening with
ribbon-cutting by Marta Brown and presentations to a busload of
students.

This (PDF) presentatation on the
experiment is well worth a read as both introduction and background.

Demo movies
These are a series of movies that I shot using our Sony DSC-V1 camera.
This is a 5 megapixel camera we bought for JCamera/PTP testing which
turned out to have inadquate PTP support. However, it can capture MPEG1
movies of any length, limited only by the size of the 'Memory Stick' in
the camera.
All of these are as they came off the camera, no editing or format
conversions performed. All are VGA (640x480), 25fps, with audio.
- MOV00478.MPG, 4.1MB, 12", T-Rex in
vertical actuation.
- MOV00479.MPG, 4.1MB, 12", T-Rex in
longitudinal motion.
- MOV00480.MPG, 2.3MB, 7", wide-angle
shot of T-Rex.
Remote particpation during the experiment
Scott Gose and myself, with the assistance of Ben Clifford at ISI, set
up a Polycom webcast of the speeches, and also video from the sites'
permanently mounted telepresence camera. I also attempted to get
streaming data configured, so that remote participants could observe it
as well, but had problems with the orb2nsds code Steve at UCLA is going to get me a set of manuals so I can finish
orb2nsds off once and for all; it was very frustrating to have
unrepairable code.
You can see the now-outdated instruction page I wrote at
this location.
Pictures
Due to the number of pictures, I've put them on a separate page. It's a
mixed lot; equipment, people, setup, shake sites, some scenery.
All taken with the same Sony camera.
