Fukushima radioisotopes leaking into the ocean: how significant?

Caesium-137 from the Fukushima meltdowns can make fish in the region near Fukushima dangerous to eat, but when it disperses into the larger ocean, it is diluted to insignificance. The total amount is trivial beside the amounts released by nuclear weapons tests and previous accidents.

Strontium-90 is potentially worse. It accumulated in bones, including fish bones. It could make small fish such as sardines, commonly eaten with the bones, dangerous to eat.

I have found no information on the level of strontium-90 in the ocean off Fukushima or in fish there.
