Interesting, but radiation killing through water?

I thought water was supposed to be an excellent protector against radiation? So was there something special about this particular radiation event (or were the levels just so high) that they negated the protective qualities of the water?

If this was a mass extinction of land animals I'd believe it in a second, but under water, hmmm. The figure I've found online is that you halve the level of radiation for every 7cm of water it passes through. To kill off underwater creatures that dont need to surface (like whales and dolphins), that must have been one hell of a radiation event, wouldnt it?
