Inorganic iodine concentrations from 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 0291397)

This dataset contains data collected on R/V Roger Revelle during cruise RR1815 in the North Pacific Ocean and South Pacific Ocean from 2018-11-01 to 2018-11-17. These data include depth. The instruments used to collect these data include BASi Controlled Growth Mercury Electrode, GO-FLO Teflon Trace Metal Bottle, and Perkin Elmer Lambda 35 Spectrophotometer. These data were collected by James W. Moffett of University of Southern California as part of the "U.S. GEOTRACES PMT: Measurement of the organic complexation and chemical lability of dissolved copper using multiple techniques (PMT Copper)" 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 2022-04-25.

Inorganic Iodine Concentrations on the GEOTRACES Pacific Meridional Transect

Dataset Description:
Acquisition Description:
Iodate and Iodide were measured along the GEOTRACES GP15 transect aboard R/V Roger Revelle. Samples were collected using the GEOTRACES trace-metal clean rosette. For the purposes of preserving the speciation, all samples were immediately frozen at -20 °C and shipped back to the United States in a cooler, overnight. The samples were kept frozen until analysis, at which point, they were defrosted. Iodate was analyzed on UV-Vis Spectrophotometer while Iodide was analyzed on the Hanging Mercury Drop Electrode with the Cathodic Square Wave Stripping Voltammetry setting. Both methods were described previously in Moriyasu et al., (2021).
