Enivronmental Sample Processor

The Environmental Sample Processor (ESP) is a robotic device that autonomously collects and analyzes subsurface water samples. CMOP is using the ESP in a unique way by deploying it in the turbid waters of an estuary, from a pier, and performing adaptive sampling targeted to the timing and characteristics of specific biological hotspots.

Environmental Sample Processor Scientista run preliminary tests on Environmental Sample Processor in OHSU lab. More testing of ESP in OHSU lab
