Figures 4–10 in New method of estimation of the relative area of perforations on valves of centric diatoms using SEM images on the example of Minidisus vodyanitskiyi Lyakh et Bedoshvili
Figures 4–10. Steps used to measure the relative area of perforations on valve SEM images. 4. The bounded ellipse is constructed using five points, and ellipse main diameters were determined. 5. Areola foramens (yellow and blue) and inorganic flakes (pink) were manually selected. 6–8. The real convex shape of areola foramens covered by filiform siliceous growth was restored using convex hull algorithm. 9. Average diameter and distance between cribral pores were measured. 10. Cribral pores were represented by hexagons and the number of those hexagons was estimated.

Fig. 1 in Procedures for Obtaining Optimal SEM Images of Coccolithophore Debris in Coccolith Limestones
Fig. 1. CCI images of coccolith material in different stages of fragmentation within faecal pellets in coccolith limestone. Cross−sections of complete and dismembered, variously oriented, coccospheres allow to observe their structures. A. Perpendicular cross−section of a coccosphere with well visible distal (d) and proximal (p) shields of placoliths joined by parallel calcite crystallites in wide central area (c). Interlocking of adjacent edges of placolith shields is particularly well visible. The structure of the central area is well visible as a net in horizontal cross−section of the plate in the right (c1), ZNG PAN B−III−75/3. B. Perpendicular cross−sections of coccospheres clearly show distal (d) and proximal (p) shields of placoliths, and central areas (c). The central areas are seen as narrow massive or open structures, depending on the orientation of cross−sections (compare c and c1). Note the very tight interlocking of adjacent edges of placolith shields and additional placoliths (x) within the coccosphere. The structures closing the central area are seen as a narrow open structure in horizontal view of placoliths (c2), ZNG PAN B−III−75/5. Both images were obtained in ESEM using SE under low vacuum, from non−coated polished thin section at WD, 10.1 mm, SS, 37 s/frame.
