What a difference a second makes.... (as automatically seen by an HPWREN motion-detect camera)

Retardant operations had a minor glitch from Ramona AAB during product transfer from Airslide trailer. Lots of clean-up required by airbase staff. The powder is moved using low air pressure from truck transfer, about 6-10 PSI as the air escapes out when powder moves inside.

NOTE: No one was hurt after the airsock broke on back of retardant trailer, causing P-100 powder burst into air surrounding operations, loading pits and way out & over T-70 in pit #1 about 100' away. The airsock lets the air out as powder goes into trailer.

Wolf (and raven) spectrum analyzer outputs from a newly deployed acoustics sensor at the HPWREN-connected California Wolf Center. The images above are rotated for better fit on this web page. /Acoustics/CWC-acsensor1.html shows the sound samples as they are being collected, only a few of them actually contain wolf howls. Clicking on either image will lead to an almost 6 megabyte sound file in .wav format.

Initial experimental setup for a wind-based power generator on the roof of the San Diego Supercomputer Center. The plan is to move it to an HPWREN site where solar power alone has proven insufficient after many cloudy days.

Mountain Empire School Science Teacher Roger Wynn is talking via LIVE-3D to National Park Service Intern and CSUCI student Nick de Roulhac at the NPS Cabrillo National Monument. Roger participated from the exhibit of this year's annual meeting of the American Association for the Advancement of Science, using special glasses to view the images from two projectors via polarizing filters. The Cabrillo National Monument setup included two cameras. Two separate simultaneous skype streams provided the video data transport.

Flash flooding illustration at the river crossing in the SDSU Santa Margarita Ecological Reserve, where it started with the water level high enough to just get feet wet. Just minutes later crossing the river would probably not be survivable, due to the river's raging nature, along with the generally rocky environment.
