Notes: Ages for chrons are from Cande and Kent (1995). (o) = onset, (t) = termination of a polarity chron. NR = a reversal where the polarity of the field changed from normal to reversed, RN = a reversal where the polarity of the field changed from reversed to normal. * = the reversal boundary is the same as identified by Shipboard Scientific Party (1999c), but the location of the boundary has been adjusted slightly. † = identification of chron and reversal boundaries is speculative; therefore, these reversal boundaries are not used in the sedimentation rate plots. ** = The reversal boundary location is identical to that given by Shipboard Scientific Party (1999c). Comments: (1) = the mudline is taken as 0-Ma sediment.
