Concentrations and stable isotopes of total and deionized water-soluble Fe, Zn, and Cd bulk aerosols and Fe concentrations and stable isotopes of coarse and fine aerosols from Leg 1 of the US GEOTRACES PMT cruise (GP15, RR1814) from Sept to Oct 2018

This dataset reports concentrations and stable isotopes of total and deionized water-soluble iron (Fe), zinc (Zn), and cadmium (Cd) bulk aerosols and Fe concentrations and stable isotopes of coarse (>0.95 micrometers (µm)) and fine (<0.95 µm) aerosols collected during Leg 1 (RR1814) of the US GEOTRACES GP15 Pacific Meridional Transect (PMT) cruise on R/V Roger Revelle from September to October 2018 on a meridional transect along 152°W from Alaska to Tahiti. Concentration and isotope data were collected by Zachary Bunnell, Dr. Matthias Sieber, and Dr. Tim Conway at the University of South Florida using a Thermo Neptune Plus MC-ICPMS following aerosol collection and processing by Dr. Clifton Buck's group. Trace metal isotope ratios are an important emerging tool in aerosols to trace aerosol sources of each metal. Data from Leg 2 of the cruise (RR1815) are available in a separate dataset.
