The name Ponar, according to the Grand Valley State University manual, comes from the Great Lakes scientists, Charles E. Powers, Robert A. Ogle, Jr., Vincent E. Noble, John C. Ayers, and Andrew Roberson. According to the Grand Valley State University manual, it states that “the Ponar grab sampler is lowered to the bottom where contact with the bottom sets off the trigger and a strong spring snaps the jaws shut trapping a sample of the bottom inside.” It is held together by two important pins, which are the safety pin and the spring pin. These pins are important because they make sure that the Ponar opens and closes securely so that sediments can be collected properly.
