Notes: Overall abundance is given as 0 = barren; 1 = trace; 2 = rare; 3 = few; 4 = common; and 5 = abundant. The dominant assemblage in each core catcher and the characteristic diatom stratigraphic zone are given. Note the occurrence of Simonseniella curvirostris in Sample 175-1081A-7H-1, 70 cm, and of S. barboi in Samples 13H-1, 70 cm, to 23X-5, 85 cm (see text).
