Introduction

This auxiliary material is one text file with high resolution jpg figures 
embedded within it. Sampling and analytical techniques (not contained in the 
paper due to length restrictions) are described in detail in this supplement 
with Figures S1 and S2. Possible caveats to these findings are explored. Figure 
S3 is described in the results section of the paper and shows the changes in 
DMS/P/O concentrations with depth.
