attribute NC_GLOBAL acquisition_description String Sample storage bottle lids and threads were soaked overnight in 2N reagent\ngrade HCl, then filled with 1N reagent grade HCl to be heated in an oven at 60\ndegrees celcius\\u00a0overnight, inverted, heated for a second day, and rinsed\n5X with pure distilled water.\\u00a0 The bottles were then filled with trace\nmetal clean dilute HCl (0.01N HCl) and again heated in the oven for one day on\neither end.\\u00a0 Clean sample bottles were emptied, and double-bagged prior\nto rinsing and filling with sample.\n \nAs stated in the cruise report, trace metal clean seawater samples were\ncollected using the French GEOTRACES clean rosette (General Oceanics Inc.\nModel 1018 Intelligent Rosette), equipped with twenty-two new 12L GO-FLO\nbottles (two bottles were leaking and were never deployed during the cruise).\nThe 22 new GO-FLO bottles were initially cleaned in LEMAR laboratory following\nthe GEOTRACES procedures (Cutter and Bruland, 2012). The rosette was deployed\non a 6mm Kevlar cable with a dedicated custom designed clean winch.\nImmediately after recovery, GO-FLO bottles were individually covered at each\nend with plastic bags to minimize contamination. They were then transferred\ninto a clean container (class-100) for sampling. On each trace metal cast,\nnutrient and/or salinity samples were taken to check potential leakage of the\nGo-Flo bottles. Prior to filtration, GO-FLO bottles were mixed manually three\ntimes. GO-FLO bottles were pressurized to less than\\u00a08 psi with 0.2-um\nfiltered N2\\u00a0(Air Liquide). For Stations 1, 11, 15, 17, 19, 21, 25, 26,\n29, 32 GO-FLO spigots were fitted with an acid-cleaned piece of Bev-a-Line\ntubing that fed into a 0.2 um capsule filters (SARTOBRAN\\u00a0300, Sartorius).\nFor all other stations (13, 34, 36, 38, 40, 42, 44, 49, 60, 64, 68, 69, 71,\n77) seawater was filtered directly through paired filters (Pall Gelman Supor\n0.45um polystersulfone, and Millipore mixed ester cellulose MF 5 um) mounted\nin Swinnex polypropylene filter holders, following the Planquette and Sherrell\n(2012) method. Filters were cleaned following the protocol described in\nPlanquette and Sherrell (2012) and kept in acid-cleaned 1L LDPE bottles\n(Nalgene) filled with ultrapure water (Milli-Q, 18.2 megaohm/cm) until use.\nSubsamples were taken into acid-cleaned (see above) Nalgene HDPE bottles after\na triple rinse with the sample. All samples were acidified back in the Boyle\nlaboratory at 2mL per liter seawater (pH 2) with trace metal clean 6N HCl.\n \nOn this cruise, only the particulate samples were assigned GEOTRACES numbers.\nIn this dataset, the dissolved Pb samples collected at the same depth\n(sometimes on a different cast) as the particulate samples have been assigned\nidentifiers as \\u201cSAMPNO\\u201d which corresponds to the particulate\nGEOTRACES number. In cases where there were no corresponding particulate\nsamples, a number was generated as \\u201cPI_SAMPNO\\u201d.\n \nUpon examining the data, we observed that the sample taken from rosette\nposition 1 (usually the near-bottom sample) was always higher in [Pb] than the\nsample taken immediately above that, and that the excess decreased as the\ncruise proceeded. The Pb isotope ratio of these samples were higher than the\ncomparison bottles as well. A similar situation was seen for the sample taken\nfrom rosette positions 5, 20 and 21 when compared to the depth-interpolated\n[Pb] from the samples immediately above and below. Also, at two stations where\nour near-bottom sample was taken from rosette position 2, there was no [Pb]\nexcess over the samples immediately above. We believe that this evidence\npoints to sampler-induced contamination that was being slowly washed out\nduring the cruise, but never completely. So we have flagged all of these\nanalyses with a \\u201c3\\u201d indicating that we do not believe that these\nsamples should be trusted as reflecting the true ocean [Pb].\n \nIn addition, we observed high [Pb] in the samples at Station 1 and very\nscattered Pb isotope ratios. The majority of these concentrations were far in\nexcess of those values observed at nearby Station 11, and also the nearby\nUSGT10-01. Discussion among other cruise participants revealed similarly\nanomalous data for other trace metals (e.g., Hg species). After discussion at\nthe 2016 GEOVIDE Workshop, we came to the conclusion that this is*- evidence\nof GoFlo bottles not having sufficient time to \\u201cclean up\\u201d prior to\nuse, and that most or all bottles from Station 1 were contaminated. We flagged\nall Station 1 data with a \\u201c3\\u201d indicating that we do not believe\nthese values reflect the true ocean [Pb].\n \nSamples were analyzed at least 1 month after acidification over 36 analytical\nsessions by a resin pre-concentration method. This method utilized the\nisotope-dilution ICP-MS method described in Lee et al. 2011, which includes\npre-concentration on nitrilotriacetate (NTA) resin and analysis on a Fisons\nPQ2+ using a 400uL/min nebulizer. Briefly, samples were poured into 30mL\nsubsample bottles. Then, triplicate 1.5mL polypropylene vials (Nalgene) were\nrinsed three times with the 30mL subsample.\\u00a0 Each sample was pipetted\n(1.3mL) from the 30mL subsample to the 1.5mL vial.\\u00a0 Pipettes were\ncalibrated daily to the desired volume.\\u00a0 25 ul of a 204Pb spike were\nadded to each sample, and the pH was raised to 5.3 using a trace metal clean\nammonium acetate buffer, prepared at a pH of between 7.95 and 7.98.\\u00a0 2400\nbeads of NTA Superflow resin (Qiagen Inc., Valencia, CA) were added to the\nmixture, and the vials were set to shake on a shaker for 3 \\u2013 6 days to\nallow the sample to equilibrate with the resin.\\u00a0 After equilibration, the\nbeads were centrifuged and washed 3 times with pure distilled water, using a\ntrace metal clean siphon tip to remove the water wash from the sample vial\nfollowing centrifugation.\\u00a0 After the last wash, 350\\u03bcl of a 0.1N\nsolution of trace metal clean HNO3 was added to the resin to elute the metals,\nand the samples were set to shake on a shaker for 1 \\u2013 2 days prior to\nanalysis by ICP-MS.\n \nNTA Superflow resin was cleaned by batch rinsing with 0.1N trace metal clean\nHCl for a few hours, followed by multiple washes until the pH of the solution\nwas above 4.\\u00a0 Resin was stored at 4 degrees celcius\\u00a0in the dark\nuntil use, though it was allowed to equilibrate to room temperature prior to\nthe addition to the sample.\n \nNalgene polypropylene (PPCO) vials were cleaned by heated submersion for 2\ndays at 60 degrees celcius\\u00a0in 1N reagent grade HCl, followed by a bulk\nrinse and 4X individual rinse of each vial with pure distilled water. Each\nvial was then filled with trace metal clean dilute HCl (0.01N HCl) and heated\nin the oven at 60 degrees celcius\\u00a0for one day on either end.\\u00a0 Vials\nwere kept filled until just before usage.\n \nOn each day of sample analysis, procedure blanks were determined. Replicates\n(12) of 300uL of an in-house standard reference material seawater (low Pb\nsurface water) were used, where the amount of Pb in the 300uL was verified as\nnegligible. The procedural blank over the relevant sessions for resin\npreconcentration method ranged from 2.2 \\u2013 9.9pmol/kg, averaging 4.6\n+/-\\u00a01.7pmol/kg. Within a day, procedure blanks were very reproducible\nwith an average standard deviation of 0.7pmol/kg, resulting in detection\nlimits (3x this standard deviation) of 2.1pmol/kg. Replicate analyses of three\ndifferent large-volume seawater samples (one with 11pmol/kg, another with\n24pmol/kg, and a third with 38pmol/kg) indicated that the precision of the\nanalysis is 4% or 1.6pmol/kg, whichever is larger.\n \nTriplicate analyses of an international reference standard gave SAFe D2: 27.2\n+/-\\u00a01.7 pmol/kg. However, this standard run was linked into our own long-\nterm quality control standards that are run on every analytical day to\nmaintain long-term consistency. \\u00a0\n \nFor the most part, the reported numbers are simply as calculated from the\nisotope dilution equation on the day of the analysis. For some analytical\ndays, however, quality control samples indicated offsets in the blank used to\ncorrect the samples. For the upper 5 depths of Station 29, all depths of\nStation 40, and the deepest 2 depths of Station 42, the quality control\nsamples indicated our blank was overcorrecting by 3.4pM, and we applied a\n-3.4pM correction to our Pb concentrations for that day. For the deepest 11\ndepths of Station 34, the quality control samples indicated our blank was\novercorrecting by 10.2pM (due to contamination of the low trace metal seawater\nstock), and we applied a -10.2 pM correction to our Pb concentrations for that\nday. With these corrections, the overall internal comparability of the Pb\ncollection should be better than 4%.\n \nThe errors associated with these Pb concentration measurements are on average\n3.2% of the concentration (0.1 \\u2013 4.4pmol/kg). Although there was a formal\ncrossover station (1) that overlaps with USGT10-01 (GA-03), sample quality on\nthe first station of GEOVIDE appears problematical making the comparison\nunhelpful. However, GEOVIDE station 11 (40.33 degrees North, 12.22\ndegrees\\u00a0West) is not too far from USGT10-01 (38.325 degrees\\u00a0North,\n9.66 degrees\\u00a0West) and makes for a reasonable comparison. It should also\nbe noted that the MIT lab has intercalibrated Pb with other labs on the 2008\nIC1 cruise, on the 2011 USGT11 (GA-03) cruise, and on the EPZT (GP-16)\ncruises, and maintains in-lab quality control standards for long-term data\nquality evaluation.\n \nTen percent of the samples were analyzed by Rick Kayser and the remaining\nninety percent of the samples were analyzed by Cheryl Zurbrick. There was no\nsignificant difference between them for the lowest concentration large-volume\nseawater reference sample (RK averaged 11.0 +/-\\u00a01.6 pmol/kg; CZ averaged\n11.6 +/-\\u00a01.6 pmol/kg).

attribute NC_GLOBAL projects_0_description String Lead is a trace metal that has historically been emitted into the atmosphere through human activities such as coal burning and the use of leaded gasoline followed by deposition into the ocean. Once introduced into the marine environment, lead is dispersed via currents and removed by biota and other sinking particles. This century-scale growth of lead emissions followed by a decline upon the phase-out of leaded gasoline is one of the great global geochemical experiments. In this study, researchers at the Massachusetts Institute of Technology will analyze archived seawater samples to improve our knowledge on the spatial and temporal variability of lead concentrations and lead isotope ratios. This data will yield new insights into the sources and transport of lead and other metals, document the time-evolving human footprint on the ocean, and assist with validating models.
