Introduction
This auxiliary material includes 14C (Data Set S1; 2009pa001871-ds01.txt)  and 210Pb data (Data Set S2; 2009pa001871-ds02.txt) used to construct chronology for cores 34GGC and 31MC, compound-specific d13C values for the upper samples from 31MC (Data Set S3; 2009pa001871-ds03.txt), and a comparison of the C28, C30, and C32 fatty acid homologs downcore in both sediment cores (Figure S1; 2009pa001871-fs01.eps).

1. 2009pa001871-ds01.txt 
Radiocarbon dates (on mixed planktonic foraminifera) for cores 31MC and 34GGC.
1.1 Column "Core", core name
1.2 Column "ID", lab accession number
1.3 Column "Depth (cm)", depth in core in centimeters
1.4 Column "14C age", Measured 14C age
1.5 Column "1s (", 1-sigma error on measured 14C age
1.6 Column "Year AD", calibrated age in AD
1.7 Column "1s_(", 1-sigma error on calibrated age.

2. 2009pa001871-ds02.txt 
210Pb data for the top of multicore 31MC, units are in becquerels/gram sediment. The linear sedimentation rate derived from these data is 0.22 cm/yr.
2.1 Column "Depth (cm)", depth in core in centimeters
2.2 Column "Unsupported 210Pb (Bq/g)", unsupported lead in units of becquerels/gram sediment

Compound-specific d13C values (vs. VPDB) for the C28, C30, and C32 fatty acids from the top six samples from core 31MC. As stated in the main text, if the leaf waxes were influenced by anthropogenic land clearance, we might expect to see an enrichment trend in d13C from increased input of tropical C4 grasses. In contrast, we observe that the uppermost samples are only slightly depleted in d13C relative to the deeper samples.
3.1 Column "Depth (cm)", depth in core in centimeters
3.2 Column "Year AD", age of sample
3.3 Column "C28", d13C vs. VPDB for the C28 fatty acid
3.4 Column "C30", d13C vs. VPDB for the C30 fatty acid
3.5 Column "C32", d13C vs. VPDB for the C32 fatty acid

Normalized dD data from the BJ8-3 cores for the C28 (green), C30 (blue), and C32 (red) n-acids. All acids record a very similar signal, with the exception of C28 from -500-0 AD. This deviation may reflect an input of C28 acid from a separate source than the other long-chain acids during this time. Since the C30 acid was slightly more abundant in the sediments than the C32 acid (and thus had a lower analytical standard deviation), it was chosen to represent dDwax.
