USGS National Innovation Center UAS Research Center Saucer Shark Project, before science flight tests, Aeroshell and payload. Sling configuration and payload orientation verified before science flight deployment. Payload is on and ready to record!

USGS National Innovation Center UAS Research Center Saucer Shark Project, BisonCore displays the path of the sensor live, as it covers transects. Data received from the payload is then displayed within the BisonCore Ecosystem and is accessible for field viewing. The magnetic map is also used to validate payload directed algorithms.

Anthony Smith photo cred. Redwood Cr at Orick, 11482500. Under 101 bridge and is also the measuring section. Provisional peak was 42,700 cfs. Looks to be the highest peak since 1975. NWS had concerns of levee capacity that night. At the gage, highwater mark which exceeded CSG's, looked to be roughly 8 ft from top of levee.

A Pacific Gas and Electric Company (PG&E) compressor station in Hinkley, California. Although hexavalent chromium occurs naturally in groundwater in the Mojave Desert, concentrations increased in Hinkley Valley beginning in 1952 when the PG&E discharged it into unlined ponds. From there, hexavalent chromium entered the aquifer.

Hexavalent chromium, a known carcinogen under specific circumstances, occurs naturally in groundwater in the Mojave Desert. However, concentrations of hexavalent chromium increased in California’s Hinkley Valley beginning in 1952 when the Pacific Gas and Electric Company (PG&E) discharged it into unlined ponds.
