Internal view of the Environmental Sample Processor

The MBARI Environmental Sample Processor—the ESP—provides on-site (in situ) collection and analysis of water samples from the subsurface ocean. The instrument is an electromechanical/fluidic system designed to collect discrete water samples, concentrate microorganisms or particles, and automate application of molecular probes which identify microorganisms and their gene products. The ESP also archives samples so that further analyses may be done after the instrument is recovered.
