Table 7. Diatom range distribution chart for Holes 1042A and 1042B. 																			

"Notes: Abbreviations for abundances are as follows: A = abundant, C = common, F = few, R = rare, B = barren, and lowercase"																			
"letters = reworked. Abbreviations for preservation are as follows: G = good, M = moderate, and P = poor."																			
" For more specific definitions refer to the ""Explanatory Notes"" chapter (this volume)."
