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.

- Scientists: Radioactivity in sea NOT falling off -- Hypothesis says Fukushima groundwater is leaking radiation
- New Study: 'Fuel rod materials' may have been released when acid seawater interacted with ruptured fuel rods, carrying radioactive materials into ground -- "Full magnitude of release has not been well documented"
- Groundwater a likely source for continued flow of radiation into ocean -- "Complete melt through" so "not surprising" discharges continue, says study
