Figure F21. Diatom abundance and preservation and abundance pattern of selected biostratigraphic and paleoenvironmental significant diatom taxa at Site 1089, correlated with the magnetostratigraphic and diatom biostratigraphic record. Abundance abbreviations: A = abundant, C = common, F = few, R = rare, T = trace; preservation abbreviations: G = good, M = moderate, P = poor. Magnetostratigraphy shading: black = normal, white = reversed.
