Fukushima’s Impact on the Ocean Analyzed, IEEE Spectrum by Prachi Patel, January 12, 2012:

[...] cesium-137 concentrations have stayed at near constant levels since July, implying that radioactive water is still being released, either directly from the reactors or indirectly from groundwater [...]

Ken Buesseler, a marine chemist at Woods Hole who is involved with researching ocean radiation off of Fukushima

“I’m convinced there are ongoing leaks” [...]

“Even if you plug all leaks and shut down reactors, groundwater keeps leaching into the ocean and these waters and contaminated sediments can be a long-term source of cesium-137 for decades to a century” [...]

Accumulation of radionuclides in marine sediment is the main concern, says Buesseler. [...]

Organisms that live in or on sediment, such as worms, shellfish, and bottom feeders, could be exposed to high radionuclide concentrations. “For a population that eats a lot of seafood, this is certainly of concern,” Buesseler says.
