The Environmental Sampler Processor (ESP) performs a variety of chemical and genetic assays on samples it takes directly from its position moored 2 to 30 meters underwater. This Linux controlled "lab in a can" was developed to identify health hazards, such as toxic algae blooms, in hours rather than days or weeks.

Initially, energy consumed by the main microprocessor and radio communications limited the duration of deployments to about 30 days. Fitfully, over the course of the last 10 years, the system's hardware, software, firmware, and requirements have evolved to reduce energy use such that year long deployments have recently became possible. The greatest energy savings were achieved with a holistic approach that is readily applicable to many other remote (IOT) devices.
