Introduction 
This auxiliary material contains a table showing the individual contributors who submitted DMS data 
to the Global Surface Seawater Dimethylsulfide Database. Their data were used to create the updated 
DMS climatology in this study. The auxiliary material also contains three figures that represent: (S1) 
the location of the 1x1 degree pixels with DMS data, (S2) the smoothed monthly first-
guess fields of sea surface DMS concentration (nM), and (S3) the latitudinal difference between the 
previous climatology (K00) and that obtained in the present study (L10). Figure S1 was constructed by 
pooling together all existing DMS data in 1 degree latitude 1 degree longitude squares; the map 
shows the squares where DMS data exist. The monthly maps of Figure S2 were created from the annual 
cycles of each biogeographical province by computing the province monthly mean concentrations 
either from in situ data or by interpolation or substitution where there were no data; transitions 
across province borders were smoothed using an unweighted 11-point filter. Figure S3 shows the % of 
difference between K00 and L10 of monthly DMS concentrations in 1 degree latitudinal bands.
