Sediment Trap

Caption

Researchers deployed time-series sediment traps 115 kilometers (approximately 70 miles) southeast of the nuclear power plant at depths of 500 meters (1,640 feet) and 1,000 meters (3,280 feet). The two traps began collecting samples on July 19, 2011 -- 130 days after the March 11th earthquake and tsunami -- and were recovered and reset annually.
