FIGURE 4. Energy dispersive spectrometer (EDS) area scan dataset. (A) EDS site of interest BSE image in a cross-sectional view of a gorgonian Plumigorgia hydroides axial skeleton acquired by INCA Energy software using same region as Figure 3, partial area scan was applied due to the visible topographical differences of the surfaces on both sides of the axis, thus only two small areas were selected for EDS analysis. Scale bar = 300 μm. (B) Bar chart of the quantitative results from (C) spectrum 1 for reference in that the analytical results of the two sites are identical as seen in Table 2.
