Subset of particulate iron, particulate sulfur, dissolved hydrogen, and dissolved methane collected during the PLUME RAIDERS cruise (RR2106) on the R/V Roger Revelle from 18 September – 6 November 2021 along the 16-18ºS section of the Southern East Pacific Rise

This dataset includes the concentrations of particulate total sulfur, particulate iron, dissolved hydrogen, and dissolved methane measurements for a subset of near-seafloor (< 40 m above bottom) and background water column samples collected on the 18 September to 6 November 2021 PLUME RAIDERS cruise to the 16-18ºS sector of the Southern East Pacific Rise on R/V Roger Revelle. Particulate iron and particulate total sulfur samples were collected at sea and later measured in lab using energy dispersive X-ray fluorescence (ED-XRF). Dissolved hydrogen and methane measurements were collected and processed shipboard using gas chromatography. Dr. Tamara Baumberger and Anson Antriasian generated the dissolved hydrogen and methane data. Nathan Buck generated the particulate iron and particulate total sulfur data.
