Environmental Sample Processor (ESP)
First Generation: ESP (1G)

The original environmental sample processor--known as ESP-1G--was developed at MBARI, by scientists, and mechanical, electrical, and software engineers (Scholin et al., in press.). The analytical capacity of the first-generation instrument was focused on a suite of marine planktonic organisms--ranging from heterotrophic and photosynthetic bacteria, archaea, and eucarya to small invertebrates found in the upper ocean.

ESP-1G deployments

The prototype ESP-1G was first deployed in the Gulf of Maine and subsequently in Monterey Bay. Some results from those deployments can be seen at the links below

Conclusions from 1G deployments

  • The ESP concept is valid.
  • Deployments in Gulf of Maine and Monterey Bay were successful
  • Monterey Bay deployment showed the potential for detecting invertebrate larvae in situ, in real time.
