Supplemental files

Tables (pdf)
1. d13C record details: core name, lat, long, depth, region code, reference.

2. Correlation coefficient and statistical significance between records,
for both untreated records and pre-whitened records including:
Composite CO2, AIP vertical d13C gradient, AP vertical d13C gradient, 
(INA/2)-DP vertical d13C gradient, global mean d13C stack

Figures (pdf)
1. Two panels of (top) AIP and AP intermediate and deep stacks, and 95% CI 
and (bottom) AIP and AP vertical d13C gradients plotted with atmospheric CO2 (pdf)

Data files - the data are presented in a consistent order across files
Note: Regional age models are from Stern and Lisiecki, 2014 (aka, SL14)
1. 1_d13c_site_files: original d13C, organized by each region in a 
	separate .csv and .xls file (9 files)
	i. README_d13c_sites
		-First row is core name 
		-Third row, three columns per core of depth (in core, (cm)), age (kyr), 
		d13c (per mil V.P.D.B.)
	ii. *region_xyz 
		csv and xls: 1st column is core name, column 2-4 are core site latitude, 		longitude, depth (meters below sea level)
		txt files: *region*_xyz (in each column: core site latitude, longitude, 		depth (meters))
	iii. xyz_117.mat: location coordinates of each region (lat, long, depth (meters))
	
	
2. 2_d13c_117records_alignedSL14: d13C records aligned to the SL14 age models and lat, 
	long, depth (meters below modern sea level) (in .mat and txt files)
	i. README_aligned_d13c.txt
	ii. 20to6ka117.mat variables: age (6:1:20 ka), and regional d13c (in separate variables) (117 d13C records aligned to SL14 age models)
	iii. txt files: *region*_d13c.txt (117 d13C records aligned to SL14 age models)
	iv. xyz_117.mat: location coordinates of each region (lat, long, depth (meters))
		
		
3. Regional d13C stacks: nine regions 
	i. README_region_d13c_stacks.txt
	ii.-iii. regional_d13c_stacks.csv, .txt, and .xls: 
		column 1: age (kyr) (6:1:20)
		Even-numbered columns: d13C stacks, d13C for each time step
		Odd-numbered columns: 95% CI half-width for each regional d13C stack (hw)	iv. regional_d13c_stacks.mat: region variables for d13c and 95% CI half-width (hw)
	
4. Volume-weighted stacks: AIP, AP, global mean d13C
	i. README_volume_weighted_d13c_stacks.txt
	ii-iii. volume_weighted_d13c_stacks.csv and .xls: d13C at each age point for each 
		volume-weighted stack and the 95% confidence interval half-width
		1. AIP intermediate
		2. AP intermediate
		3. AIP deep
		4. AP deep
		5. AIP gradient
		6. AP gradient
		7. Global mean d13C
