This OP is stating radiation has reached US shores, whilst the other is stating is has not.
The project includes the participation of 19 academic and government institutions and three other organizations/businesses, and samplings will take place several times in 2014, with the processed samples sent to the Lawrence Berkeley National Lab’s Low Background Facility. As the project makes progress, findings will be posted for public access.
Sampling will take place several times in 2014, and processed kelp samples will be sent to the Lawrence Berkeley National Lab’s Low Background Facility for detailed radionuclide analysis. As data becomes available it will be posted for public access.

Yes. It will. When the "plume" reaches the west coast.
And yes, it will be very diluted. Far below risk levels.
On the contrary. There are a number of modelling studies which show the diluted contaminants reaching the west coast. It will get there, but as you say, "not a whole lot".
The isotopes are heavier than water and will move along the sea floor as stated by prior oceanographers. The continental shelf will also keep it from reaching our shores. We might get some but not a whole lot.
Seems that the author may have jumped the gun!
“We’re trying to figure out how much is there and how much is getting into the ecosystem,” said Dr. Matthew Edwards, a professor from San Diego State University. “Things are linked a little more closely than sometimes we’d like to think. Just because it is on the other side of the world doesn’t mean that it doesn’t effect us.”
