Live Data from the Samish ESP

The Environmental Sample Processor (ESP) is an advanced biosensor. It remotely and autonomously samples the water, conducts molecular analyses to look for target organisms, and telemeters the results to scientists at their desks in near real-time. Below are live data from the 2013 Samish Bay ESP deployment.

Vibrio parahaemolyticus (Vp) is a naturally occurring marine bacterium that accum ulates in shellfish and can cause gastroenteritis in humans. The gene for the ­t­hermo­labile hemolysin (tlh) is present in all strains of Vp, whereas the genes for the thermostable direct hemolysin (tdh) and urease (ureR) are present in only some strains of Vp that are more likely to be make people sick.

Bacteria in the Bacteroides genus are abundant in fecal material, and can be used to distinguish bovine (BoBac) from human (BacHum) sources.
