Professor on PBS: “Consolidated mass” of radioactive water “moving in unison” across Pacific to West Coast — Study: Fukushima nuclear material stays “confined to a narrow band” in ocean — “Very little dispersion” (MAP & AUDIO)

KPBS, Feb. 13, 2014 (at 3:30 in) — Q: There have been a number of reports of the so-called ‘Fukushima plume’ — is this the radioactivity that you’re hoping to track or monitor with this project? Matt Edwards, San Diego State University: It’s definitely linked to that, yeah. When we talk about a plume of water, we’re really talking about is a consolidated mass of water that’s moving in unison. That’s happening here. But also, when you’re dealing with currents, and water, and motion of the ocean, things just dissipate, they basically become more dilute — more dilute as they spread out. If you think about putting cream in your coffee and you just put a little bit of motion to your coffee, the cream doesn’t stay there in nice striated patterns, it really becomes kind of uniformly dissolved throughout — the same thing kind of happens in the ocean.
Predicting the spread of nuclear radiation from the damaged Fukushima Nuclear Power Plant (pdf), State Oceanic Administration of China, published May 12, 2011 (emphasis added): […] The ocean circulation model indicates that the nuclear material would be slowly transported northeast of Fukushima and reach 150°E in 50 days, and the nuclear debris in the ocean would be confined to a narrow band. […] The nuclear debris would be transported northward by the ocean currents initially, approach 38.5°N, and turn eastward 20 days later. […] The nuclear debris in the ocean would be confined to a narrow band.
What happens to this “narrow band” of confined nuclear material as it approaches West Coast?
