Figure 4. A. Presence/absence of G. menardii (shaded) and N. dutertrei (hatched). The presence of warm-water fauna indicates a strong Angola Current influence. The absence of the species correlates with an influx of subantarctic diatom species. B. Dissolution (dashed line with triangles) and abundance (solid line with circles). Abundance is classified as 0 = barren; 1 = trace; 2 = rare; 3 = few; 4 = common; and 5 = abundant. Dissolution is grouped as 2 = some dissolution; 4 = moderate dissolution; and 5 = no dissolution.
