Fukushima Meltdown Has Not Polluted the Entire Pacific, No Need to Panic!

That image is being widely misrepresented as radiation spread, when it was instead mapping the height of Tsunami waves.  The article went on to say

Does that mean we are all safe and can continue to live as though it is safe to eat anything in the ocean? Absolutely not, we have been dumping radiation into the environment for decades. Many species of fish travel this circle of ocean currents too, and will pick up increasing contamination with every swim by Japan. Little creatures that live in the ocean bottom near the reactor will stir up the sand and mud, and release some of the particles that are the worst, releasing those radioactive particles into the water and absorbing them at ever-increasing rates. Big fish eat little fish, and the problem escalates right up the food chain.
