Introduction

This supplement contains the previously unpublished isotopic data. Methods are described in this paper. The data that was previously published in Lund et al. (2006) is not included in this supplement.

1. 2008pa001717-ds01.txt  
This data set contains the age model control points.  Column 1 Core = Core name.  Column 2 Depth = Depth in core (cm), Column 3 Species = foraminifera species used in radiocarbon analysis, Column 4 14C_Age = Radiocarbon ages calculated using 5568 (yrs) as the half-life of radiocarbon and are reported without reservoir corrections or calibration to calendar years, Column 5 Error = Age error in radiocarbon measurement (larger of the internal or external errors), Column 6 Calendar_Age = Calendar Age calculated using Calib 5.0.2 and Marine curve, Column 7 Note = Age model note (1=date used as age model control point, 2 = date not used as age model control point, 3= Average of dates at depths above and below and used as control point in age model)

2. 2008pa001717-ds02.txt  
This data set contains the down core isotopic data and age models.  For each core there are 3 lines of header information, 1 line of column labels, followed by a variable number of lines of data.  Column 1 Depth = Depth in core (cm), Column 2 d13C = average d13C (per mil PDB), Column 3 d18O = average d18O (per mil PDB), Number = number of individual foraminifers contributing to each average, Species = species analyzed, Laboratory = where analyzed, Quality = Quality code, Age = Age in calendar yrs BP.


Species Code: 1 = C. pachyderma, 2= P. ariminensis, 3 = C.  
wuellerstorfi, 4 = C. sp., 999 = G. sacculifer


Laboratory Code: 1 = LDEO Isoprime/Multiprep, 2 = WHOI MAT252/253 Kiel, 3 = Georgia Tech Isoprime/Multiprep


Quality Code: 1= OK, 0= not used in average
