attribute NC_GLOBAL acquisition_description String Sample storage bottle lids and threads were soaked overnight in 2N reagent
grade HCl, then filled with 1N reagent grade HCl to be heated in an oven at 60
degrees celcius\u00a0overnight, inverted, heated for a second day, and rinsed
5X with pure distilled water.\u00a0 The bottles were then filled with trace
metal clean dilute HCl (0.01N HCl) and again heated in the oven for one day on
either end.\u00a0 Clean sample bottles were emptied, and double-bagged prior
to rinsing and filling with sample.

As stated in the cruise report, trace metal clean seawater samples were
collected using the French GEOTRACES clean rosette (General Oceanics Inc.
Model 1018 Intelligent Rosette), equipped with twenty-two new 12L GO-FLO
bottles (two bottles were leaking and were never deployed during the cruise).
The 22 new GO-FLO bottles were initially cleaned in LEMAR laboratory following
the GEOTRACES procedures (Cutter and Bruland, 2012). The rosette was deployed
on a 6mm Kevlar cable with a dedicated custom designed clean winch.
Immediately after recovery, GO-FLO bottles were individually covered at each
end with plastic bags to minimize contamination. They were then transferred
into a clean container (class-100) for sampling. On each trace metal cast,
nutrient and/or salinity samples were taken to check potential leakage of the
Go-Flo bottles. Prior to filtration, GO-FLO bottles were mixed manually three
times. GO-FLO bottles were pressurized to less than\u00a08 psi with 0.2-um
filtered N2\u00a0(Air Liquide). For Stations 1, 11, 15, 17, 19, 21, 25, 26,
29, 32 GO-FLO spigots were fitted with an acid-cleaned piece of Bev-a-Line
tubing that fed into a 0.2 um capsule filters (SARTOBRAN\u00a0300, Sartorius).
For all other stations (13, 34, 36, 38, 40, 42, 44, 49, 60, 64, 68, 69, 71,
77) seawater was filtered directly through paired filters (Pall Gelman Supor
0.45um polystersulfone, and Millipore mixed ester cellulose MF 5 um) mounted
in Swinnex polypropylene filter holders, following the Planquette and Sherrell
(2012) method. Filters were cleaned following the protocol described in
Planquette and Sherrell (2012) and kept in acid-cleaned 1L LDPE bottles
(Nalgene) filled with ultrapure water (Milli-Q, 18.2 megaohm/cm) until use.
Subsamples were taken into acid-cleaned (see above) Nalgene HDPE bottles after
a triple rinse with the sample. All samples were acidified back in the Boyle
laboratory at 2mL per liter seawater (pH 2) with trace metal clean 6N HCl.

On this cruise, only the particulate samples were assigned GEOTRACES numbers.
In this dataset, the dissolved Pb samples collected at the same depth
(sometimes on a different cast) as the particulate samples have been assigned
identifiers as \u201cSAMPNO\u201d which corresponds to the particulate
GEOTRACES number. In cases where there were no corresponding particulate
samples, a number was generated as \u201cPI_SAMPNO\u201d.

Upon examining the data, we observed that the sample taken from rosette
position 1 (usually the near-bottom sample) was always higher in [Pb] than the
sample taken immediately above that, and that the excess decreased as the
cruise proceeded. The Pb isotope ratio of these samples were higher than the
comparison bottles as well. A similar situation was seen for the sample taken
from rosette positions 5, 20 and 21 when compared to the depth-interpolated
[Pb] from the samples immediately above and below. Also, at two stations where
our near-bottom sample was taken from rosette position 2, there was no [Pb]
excess over the samples immediately above. We believe that this evidence
points to sampler-induced contamination that was being slowly washed out
during the cruise, but never completely. So we have flagged all of these
analyses with a \u201c3\u201d indicating that we do not believe that these
samples should be trusted as reflecting the true ocean [Pb].

In addition, we observed high [Pb] in the samples at Station 1 and very
scattered Pb isotope ratios. The majority of these concentrations were far in
excess of those values observed at nearby Station 11, and also the nearby
USGT10-01. Discussion among other cruise participants revealed similarly
anomalous data for other trace metals (e.g., Hg species). After discussion at
the 2016 GEOVIDE Workshop, we came to the conclusion that this is*- evidence
of GoFlo bottles not having sufficient time to \u201cclean up\u201d prior to
use, and that most or all bottles from Station 1 were contaminated. We flagged
all Station 1 data with a \u201c3\u201d indicating that we do not believe
these values reflect the true ocean [Pb].

Samples were analyzed at least 1 month after acidification over 11 mass
spectrometry sessions by the method of Reuer et al. (2003) as modified by
Boyle et al. (2012) and further slightly modified as noted in the following:

Double magnesium hydroxide co-precipitation followed by anion exchange
purification: This method is a slight adaptation of the isotope ratio method
of Reuer et al., 2003, which was further modified as described by Boyle et al.
(2012) and as slightly revised as described below. The method includes low-
blank pre-concentration by Mg(OH)2\u00a0co-precipitation and isotope ratio
analysis on a GV/Micromass IsoProbe multicollector ICPMS using a 50 uL/min
nebulizer aspirated into an APEX/SPIRO desolvator, using post-desolvator trace
N2\u00a0addition to boost sensitivity.

Nalgene polypropylene separatory funnels (1000mL) and Corning 50 ml conical
centrifuge vials were cleaned by heated submersion for 2 days at 60 degrees
celcius\u00a0in 1N reagent grade HCl, followed by a bulk rinse and 4X
individual rinse of each vial with pure distilled water. Each vial was then
filled with trace metal clean dilute HCl (0.01N HCl) and heated in the oven at
60 degrees celcius\u00a0for one day on either end.\u00a0 Centrifuge vials were
kept filled until just before usage.

The separatory funnels were rinsed with distilled water after each use and
then filled with high-purity distilled water spiked with high-purity HCl
(final concentration 0.01N) between uses.

1000mL polypropylene separatory funnels (Nalgene) were weighed and rinsed one
time with seawater sample, then filled with 500ml of sample.
Mg(OH)2\u00a0coprecipitation was induced by minimal addition of high-purity
ammonia solution and mixing (typically 8uL ammonia per 1mL seawater sample).
The separatory funnels were left to settle overnight, then agitated to move
the precipitate down the funnel walls. After complete settling, the
precipitate was drawn from the bottom of the funnels into a 50mL conical
centrifuge tubes. The solution/precipitate mix was centrifuged and the
solution siphoned off, and then the precipitate was dissolved in a minimal
amount of high-purity 6N HCl before undergoing another ammonia addition and
Mg(OH)2\u00a0coprecipitation. The mixture was centrifuged and the overlying
solution was siphoned.

Eichrom AG-1x8 resin was cleaned by three batch rinses with 6N trace metal
clean HCl for a 12 hours on a shaker table, followed by multiple washes with
distilled water until the pH of the solution was above 4.5. Resin was stored
at room temperature in the dark until use.

The precipitate was dissolved in 1 ml of high purity 1.1M HBr. The amount of
solution was adjusted depending on the Si concentration of the seawater
sample; if too little solution is used, the Si precipitates as a gel, impeding
the column separation. The resin in the column was first cleaned with 6M HCl,
equilibrated with 1.1M HBr, and then sample was loaded onto the column. The
column was then washed with 1.1M HBr followed by 2M HCl and then eluted with
6M HCl. The samples in a 5 ml Savillex PTFE vial were then taken to dryness on
a hotplate in a recirculating filtered air fume hood, and stored sealed until
analysis.

Just before analysis, samples were dissolved for several minutes in 10\u03bcl
concentrated ultrapure HNO3. Then, an appropriate volume of ultrapure water
was added (typically 400ul) and spiked with an appropriate amount of Tl for
mass fractionation correction. IsoProbe multicollector ICPMS Faraday cups were
used to collect on 202Hg, 203Tl, 205Tl, 206Pb, 207Pb, and 208Pb. An Isotopx
Daly detector with a WARP filter was used to collect on 204Pb+204Hg. This Daly
detector is a revised version that eliminates a reflection problem with the
electronic circuitry of the previous version. We do not report 206Pb/204Pb
data for samples run on the old Daly detector. Because the deadtime of the
Daly detector varied from day to day, we calibrated deadtime on each day by
running a standard with known 206Pb/204Pb at a high 204 count rate. The
counter efficiency drifts during the course of a day, so we established that
drift by running a standard with known 206Pb/204Pb (and a 204 count rate
comparable to the samples) every five samples. Tailing from one Faraday cup to
the next was corrected by the 209Bi half-mass method as described by Thirlwall
(2000).

On each analytical date, we calibrated the instrument by running NBS981 and
normalized measured sample isotope ratios to our measured raw NBS981 isotope
ratios to those established by Baker et al. (2004). Using this method for 22
determinations of an in-house standard (\u201cBAB\u201d) shows that for
samples near the upper range of the Pb signals shown for samples (~1V),
206Pb/207Pb and 208Pb/207Pb can be reproduced to 200ppm. Low-level samples
will be worse than that, but generally better than 1000ppm in this data set.
Because of the drift uncertainty in the Daly detector, 206Pb/204Pb for samples
in the mid-to-upper range of sample concentrations will be at best
reproducible to 500ppm.

We have intercalibrated Pb isotope analyses with two labs as reported in Boyle
et al. (2012). Since that report, two more labs have added intercalibration
data. The outcome of that intercalibration suggests that the accuracy of our
measurements approaches the analytical reproducibility we note above.

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.
