[...] Radioactivity readings in the seawater across the track ranged from less than 3 Bq per m3 up to 4,000 Bq per m3.
The maximum of these readings is about 1,000 times what could be measured in the water under normal conditions but they were about one-tenth the levels generally considered harmful, [WHOI marine chemist Ken Buesseler] noted, AP reports.
The cruise did not find these highest detections in areas sampled closest to Fukushima because swirling ocean currents formed concentrations of the radioactive compounds. At the same time, the researchers were not permitted any closer than 30km to the coast. [...]

[...] Analysis revealed elevated levels of radioactive elements that could be tied directly to releases from the nuclear power station.
These included caesium-137 and caesium-134. Radioactivity readings in the seawater across the track ranged from less than three becquerels per cubic metre up to 4,000 becquerels per cubic metre.
The maximum of these readings is about a thousand times what could be measured in the water prior to the nuclear accident.
Interestingly, the cruise found these highest detections were not in areas sampled closest to Fukushima. [...]
