We had been studying to implement sampling surveys on the ocean soil, 
completed preparations and conducted the surveys on April 29, 2011. 
                                     (Previously announced on May 3, 2011)
 
We conducted nuclide analysis for the ocean soil sampled on October 13. As 
a result, radioactive materials were detected as shown in the appendix.
 
Out of seven sampling points, the sampling surveys planned at one coastal 
sea area and three offshore sea areas yesterday were cancelled due to bad 
weather, etc.
 
Today, we reported the results to NISA and the government of Fukushima 
Prefecture.
 
We will continuously conduct the same sampling surveys.
