3.4.2 Depth ui Mixing. D. The analyses of samples from various depths are included in Appendix The summary of these results (Table 3.7) show beta activity of the surface samples. and the integrated area under the curve for depth versus beta activity of sample. This area is representative of the total activity contained under a square centimeter of ocean surface. The surface and total activity are plotted in Figure 3.26.
