Environmental Observatory Research Value
“Mapping, Tracing, and Wireless Sensor technologies may do for ecology in the 21st century what DNA sequencing did for genetics in the 20th century.” – Beth Burnside, molecular biologist
and Vice Chancellor for Research at UCB
Spatial extents & frequency from 52 Articles from Ecology Journal 2003 -2004 (Porter, BioScience, 2005).
Definition: An environmental sensor observatory is a distributed array of sensors connected by a network that is aggregated into a single dataset.
It becomes an observatory when the combination of sensors provides information not possible to achieve by individual sensors.
Sensors: Keck HydroWatch Project
PI: Inez Fung, Atmospheric Scientist, Climate modeler

Description: Daniella, Jasper and I visited the site this past weekend. Unfortunately a bear did some damage recently. It systematically knocked over and chewed on everyone of the plastic bag covered resistance probes. They were each snapped at the soil boundary. I haven't had a chance to check to see when this might have happened according to the online record. The bear also knocked over the rainfall collector (James says he has found teeth marks in it before). It broke the extended plastic tube on well 7 and the wooden stake holding up the plastic tarp. and it knocked off the cap of well 6. We didn't detect other damage-- but there could be some. I encourage you all to check your favorite on line device. We put the cap back on 6, propped up well 7 tube and put back a stake. and reset up the rain collector.
