Figure 7. Distribution of Radioactivity in Surface Waters of the Barents, Kara and Greenland Seas. 

 A: Distribution of radioactivity ('^^Cs), based on 1982 daU; B: Hypothetical distiibution of radioactivity of sur- 

 face waters of Barents and Kara Seas if the source of the radioactivity had been ti-ansport by currents from 

 northern seas. Hatching indicates areas of high and low concentrations (near Spitzbergen Island) that cannot be 

 explained by transport from the Arctic Sea alone. Arrows: directions of major currents.
