This dataset includes concentrations of suspended particulate total mercury and monomethylmercury from 18 full-depth stations (16 depths each), and 4 stations on the South American margin (5–8 depths). Suspended particle samples (1 and 51 µm) were collected with a multiple-unit large-volume in situ filtration system.

Location and timing: October–December, 2013 from Manta, Ecuador to Papeete, Tahiti.

The section included stations between 10–15 °S from the Peru margin to 152 °W north of Tahiti. Samples were collected from the surface at 2 m to the ocean floor, as deep as 5500 meters. The section captured a buoyant hydrothermal vent plume extending over 4000 km west from the East Pacific Rise.
