A field crew member stops to smile for a photo during sediment sampling on the Klamath River. The sediment sampler is lowered from a truck-mounted crane across the channel to collect measurements at multiple locations.

The U.S. Geological Survey (USGS) California Water Science Center is employing specific types of soil moisture probes to monitor watersheds, creeks, and streams as part of their hydrological studies and environmental monitoring efforts.

A soil moisture data logger buried in the ground is a specialized instrument designed to measure and record the moisture content of soil over time. Here's how it generally functions:

A USGS scientist meets with a Hinkley resident at research site to discuss the details of a geophysical survey.

Additional analyses at a USGS lab in Menlo Park were also conducted, but not before the Technical Advisory Committee was given a tour of the USGS and an explanation of all that is entailed. In this photo, a USGS scientist explains data from the mobile laboratory to members of the Hinkley community.
