Sediment Trap (IMAGE) Woods Hole Oceanographic Institution Caption To collect the particles of sinking phytoplankton, the scientific team used 6-foot-wide, funnel-shaped sediment traps at several locations across the North Atlantic, including the Sargasso Sea, the subarctic North Atlantic near Iceland, and the western North Atlantic near Massachusetts. The traps were submerged at depths of 150 meters for 24 hours and then the collected particles were analyzed in the lab.
