Detailed Description
Pore-water profilers (foreground) in a wetland between Upper Klamath and Agency Lakes, Oregon. USGS scientists developed the profilers (U.S. Patent # US 8,051,727) to provide detailed information on the quality of water in sediment pores with depth. The concentration profiles help the scientists determine the movement of solutes, such as phosphate, into and out of bottom sediments.
