Table 5. Elemental composition of the exhumed carcasses and sediment particles: SEM/EDX point analysis (at 15 keV, on copper support). Content of the elements is shown (wt% as oxides) in the exhumed and rinsed nauplii (Body) and in the adhered sediment particles (Particles). See examples of the points in Figure 5.
