Abstract
This report synthesizes actions and lessons learned by the National Oceanic and Atmospheric Administration
(NOAA) and the overall marine debris community through efforts to detect marine debris caused by the tsunami
that struck Japan in March 2011. This tsunami inundated over 217 square miles of coastal Japan and washed an
estimated 5 million tons of debris out to sea as it receded. The Japanese government estimated that 70 percent of
that total sank immediately, leaving 1.5 million tons of Japan tsunami marine debris (JTMD) that broke up and
dispersed over the North Pacific in the months and years following the tsunami.
