attribute	NC_GLOBAL	summary	String	During September 23 to November 22, 2018, the R/V Roger Revelle completed a trace element (and their isotopes) hydrographic section along ~152° West from 56° North to 20° South (GEOTRACES GP15). Full water column trace metal clean samples were obtained with the U.S. GEOTRACES Carousel (GTC) composed of 24 12-liter trace metal clean GO-Flow sampling systems mounted on a trace metal free powder-coated titanium rosette system. Three of the stations had lead (Pb) concentrations determined at Massachusetts Institute of Technology (MIT) by isotope dilution quadrupole inductively coupled plasma mass spectrometry (ICPMS) for intercalibration with the Texas A&M (TAMU) lab of Jessica Fitzsimmons who analyzed all of the cruise stations. The rest of the full- and super-stations were analyzed at MIT for Pb isotope ratios (206Pb/207Pb, 208Pb/207Pb, 206Pb/204Pb). These data are collected to document the penetration of atmosphericly-transported anthropogenic Pb into the ocean and its subsequent dispersion by circulation and chemical interactions between sinking particles and Pb dissolved in solution. Shuo Jiang, Nathan Lanning, and Edward Boyle performed the extractions and the ICPMS analyses. This dataset includes data from Leg 1 of the cruise, RR1814.
