This peristaltic pump, located in the walk-in cooler known as Big Antarctica, is used to filter water from the incubation samples. The colored tape on each graduated cylinder corresponds to the colors of each incubation group (A-F). As water flows through the pump (right) it travels through tubes to a filter. Diatoms are collected on the filter and the water collects in the graduated cylinders. Aboard the Nathaniel B. Palmer.
