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 diatom stratigraphic zone (after Barron, 1985) are given. Note the occurrence of Proboscia (= Simonseniella) curvirostris in Sample 175-1083A-8H-CC and of P. barboi in Samples 15H-CC through 22H-CC.
