Title: Concentrations of deionized water-soluble aerosol trace elements collected from bulk aerosol samples on Leg 2 (Hilo, HI to Papeete, French Polynesia) of the US GEOTRACES PMT cruise (GP15, RR1815) on R/V Roger Revelle from Oct-Nov 2018 (NCEI Accession 0277904)
Abstract: This dataset contains chemical and physical data collected on R/V Roger Revelle during cruise RR1815 in the North Pacific Ocean and South Pacific Ocean from 2018-10-25 to 2018-11-23. These data include Iron and Manganese. The instruments used to collect these data include Aerosol Sampler, Anemometer, Data Logger, and Inductively Coupled Plasma Mass Spectrometer. These data were collected by William M. Landing of Florida State University and Christopher Marsay and Clifton S. Buck of Skidaway Institute of Oceanography as part of the "Collaborative Research: US GEOTRACES PMT: Quantification of Atmospheric Deposition and Trace Element Fractional Solubility (PMT Aerosol Collection)" and "US GEOTRACES Pacific Meridional Transect (U.S. GEOTRACES PMT)" projects and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-01-11.

GP15 DI Water Soluble Aerosols Leg 2

Dataset Description:
Acquisition Description:
A total of 11 48-hour integrated aerosol samples were collected during Leg 2 of the US GEOTRACES Pacific Meridional Transect research cruise (GP15), which took place on the RV Revelle (cruise RR1815) during October-November 2018. The cruise track consisted of a southward transect across the Pacific Ocean between Hawaii and Tahiti.

Bulk aerosol samples for multiple trace element analyses were collected using one of five Tisch Environmental high-volume (~1 m³ air min⁻¹) aerosol samplers (model 5170V-BL). For each deployment, 12 replicate 47 mm diameter Whatman 41 filters were loaded on open-face filter holders (Advantec MFS) installed on the aerosol sampler on a PVC adaptor plate (Shelley et al., 2015). Filters were acid-washed before use to reduce trace element blanks, following the procedure described by Morton et al. (2013). The samplers were deployed on the forward rail of the ship's 03 deck approximately 16m above sea level, to minimize the influence of sea spray on samples. Samplers were controlled by wind speed and direction, through a Campbell Scientific CR800 data-logger interfaced with an anemometer and wind vane set up in close proximity to the samplers, in order to eliminate contamination from the ship's stack exhaust. This setup was used to restrict sampling to periods when relative wind speed and direction were >0.5 m s⁻¹ and from within ±60° of the bow of the ship, respectively, for at least five continuous minutes.
