Row Type Variable Name Attribute Name Data Type Value

attribute NC_GLOBAL acquisition_description String Large-volume particulate samples were collected using McLane Research in-situ
pumps (WTS-LV Standard Model). The wire-out was used to target depths during
deployment, and a self-recording Seabird 19plus CTD deployed at the end of the
line was used to correct for actual depths during pumping.

Filter holders used were 142 mm-diameter filter holders with a titanium
baffle. Filter holders were loaded with paired 0.8 \u00b5m Pall Supor800
polyethersulfone filters. Each cast also had \"dipped blank\" filters
deployed. These were single filters, either 0.2 \u00b5m or 0.8 \u00b5m,
deployed inside Ziploc bags with holes cut in them to expose the filters to
seawater, attached with plastic cable ties to a pump frame, and deployed.
Dipped blank filters were exposed to seawater for the length of the deployment
and processed and analyzed as regular samples, and thus functioned as full
seawater process blanks. We analyzed 1/4 portions of the dipped blank from
each pump cast.

All filters and filter holders were acid leached prior to use according to
methods recommended in the GEOTRACES sample and sample-handing Protocols
(Geotraces 2010).

Analytical methods for particulate radionuclides:
Filters were folded into 60 mL Teflon jars and weighed aliquots of
artificial isotope yield monitors 229Th (1 pg) and 233Pa (0.3-0.4 pg) and 7-8
mg dissolved Fe were added to each sample, which then sat overnight in 5 mL
16M HNO3 [All acids and bases used were Fisher Chemical OPTIMA grade or
equivalent from Trace Metal grade acids re-distilled in a Savillex\u2122
DST-1000 sub-boiling still]. The next day, the filters were heated for ~1 hour
at 180\u00b0C, at which point 4-5 ml HClO4 was added and the hot plate
temperature was increased to 220\u00b0C. Samples were heated until dense white
fumes appeared. After 10-20 minutes, the samples were covered with a Teflon
watch cover. After 30-60 minutes, rapid oxidation of the Supor material would
occur, at which point the Supor material was almost completely broken down.
The watch glasses were removed and beaker walls were rinsed down with 3 ml 8N
HNO3. Ten drops of HF were added, and the samples were heated at 220\u00b0C
until the HClO4 dried down to a viscous residue.

The sample residue was taken up in dilute HCl, and transferred to 50 mL
centrifuge tubes with Milli-Q water rinses. Fifteen to 25 drops of NH4OH were
added to raise pH to 8-8.5 when iron (oxy)hydroxide precipitated. This
precipitate was then centrifuged, supernatant was decanted, and the
precipitate was washed with Milli-Q H2O. These step were repeated. The
precipitate was then dissolved in 12 M HCl , ready for a series of anion-
exchange chromatography steps to purify Th and Pa, as outlined in Anderson et.
al., 2012. The purified Th and Pa solutions were dried down at 180-220\u00b0C
in the presence of 2 drops of HClO4 and taken up in 0.5 mL of 0.16 M
HNO3/0.026 M HF for mass spectrometric analysis.

Concentrations of 232Th, 230Th and 231Pa were calculated by isotope dilution,
relative to the calibrated tracers 229Th and 233Pa added at the beginning of
sample processing. Analyses were carried out on a Thermo-Finnegan ELEMENT XR
Single Collector Magnetic Sector ICP-MS, equipped with a high-performance
Interface pump (Jet Pump), and specially-designed sample (X) and skimmer (Jet)
cones to ensure the highest possible sensitivity. All measurements were made
in low-resolution mode (\u2206m/M\u2248300), peak jumping in Escan mode across
the central 5% of the flat-topped peaks. Measurements were made on a
MasCom\u2122 SEM; 229Th, 230Th,231Pa and 233Pa were measured in Counting mode,
while the 232Th signals were large enough that they were measured in Analog
mode. Two solutions of SRM129, a natural U standard, were run multiple times
throughout each run. One solution was in a concentration range where 238U and
235U were both measured in counting mode, allowing us to determine the mass
bias/amu (typical values varied from -0.01/amu to 0.03/amu). In the other,
more concentrated solution, 238U was measured in Analog mode and 235U was
measured in Counting mode, yielding a measurement of the Analog/Counting
Correction Factor. These corrections assume that the mass bias and Analog
Correction Factor measured on U isotopes can be applied to Th and Pa isotope
measurements. Each sample measurement was bracketed by measurement of an
aliquot of the run solution, used to correct for the instrumental background
count rates. To correct for tailing of 232Th into the minor Th and Pa
isotopes, a series of 232Th standards were run at concentrations bracketing
the expected 232Th concentrations in the samples. The analysis routine for
these standards was identical to the analysis routine for samples, so we could
see the changing beam intensities at the minor masses as we increased the
concentration of the 232Th standards. The 232Th count rates in our Pa
fractions are quite small, reflecting mainly reagent blanks, compared to the
232Th signal intensity in the Th fraction. The regressions of 230Th, 231Pa,
and 233Pa signals as a function of the 232Th signal in the standards was used
to correct for tailing of 232Th in samples.

In addition to laboratory procedural blanks (reagents/labware blanks) and
periodic measurements of an intercalibrated working standard solution of
232Th, 230Th and 231Pa, SW STD 2015-1, we also analyzed \"dipped blank\"
filters, mentioned above, to determine the total blank, associated with the
sample collection and handling in addition to the laboratory procedure.

We pooled all procedural blank-corrected \"dipped\" blanks to determine filter
blank corrections. That is, the data were corrected by the average dipped
blank values. Averages for \u201cdipped\u201d filter blanks from SO245 for a
1/4 filter fraction for 232Th, 230Th, and 231Pa at LDEO were 8.67 \u00b1 4.26
pg, 1.56\u00b10.7 fg, and 0.09 \u00b1 0.04 fg, respectively.

Further details on analysis of seawater particulate radionuclides are given by
Anderson et al. (2012).

Derived Parameters:
Th_230_TP_XS_CONC_PUMP \- The total particulate excess Th-230 refers to the
measured total particulate Th-230 corrected for a contribution of Th-230
originating from U-bearing minerals or lithogenic Th-230. Some of this
lithogenic Th-230 will be still intact within minerals and some after partial
dissolution will have adsorbed to particle surface to contribute in part to
the total adsorbed Th-230. Using the measured total particulate Th-232 and a
lithogenic Th-230/232 atomic ratio of 4e-6, and not taking into account the
fact that some of the measured particulate Th-232 is adsorbed, corrects for
all of the lithogenic Th-230 whether it be adsorbed or within intact minerals.
This excess Th-230 is what should be used in scavenging or particle flux
studies where it is desired to compare particulate Th-230 concentrations to
Th-230 production by decay of uranium dissolved in seawater. An additional
conversion factors converts picomoles to micro-Becquerels.

Th_230_TP_XS_CONC_PUMP = Th_230_TP_CONC_PUMP \u2013 4.0e-6 * 1.7473e5 *

Pa_231_TP_XS_CONC_PUMP \- The total particulate excess Pa-231 refers to the
measured total particulate Pa-231 corrected for a contribution of Pa-231
originating from U-bearing minerals or lithogenic Pa-231. Some of this
lithogenic Pa-231 will be still intact within minerals and some after partial
dissolution will have adsorbed to particle surface to contribute in part to
the total adsorbed Pa-231. Using the measured total particulate Th-232 and a
lithogenic Pa-231/Th-232 atomic ratio of 8.8e-8, and not taking into account
the fact that some of the measured particulate Th-232 is adsorbed, corrects
for all of the lithogenic Pa-231 whether it be adsorbed or within intact
minerals. This excess Pa-231 is what should be used in scavenging or particle
flux studies where it is desired to compare particulate Pa-231 concentrations
to Pa-231 production by decay of uranium dissolved in seawater. An additional
conversion factor converts picomoles to micro-Becquerels.

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:
With funding from this RAPID award, an American research team at the Lamont-Doherty Earth Observatory of Columbia University will study the supply and removal of trace elements in the South Pacific Subtropical Gyre (SPSG). This will be done in the context of an international program (UltraPac) under the direction of Dr. Tim Ferdelman of the Max Planck Institute in Breman, Germany, who has invited the Lamont-Doherty team to join the German scientists aboard their expedition on the Research Vessel Sonne (December 2015 - January 2016) between Antofagasta, Chile and Wellington, New Zealand. UltraPac is a coordinated interdisciplinary study of the SPSG, including research on microbiology, molecular biology, zooplankton, aerosols, trace metals, nitrogen fixation, carbon and nutrient biogeochemistry, among other topics. The American team will measure dissolved and particulate concentrations of long-lived, naturally-occurring radioisotopes in the uranium and thorium decay series that can be used to provide constraints on the rates of supply and removal of trace elements within this regime. The project will also provide education, training and professional development for two PhD students that would otherwise be unavailable through other aspects of their PhD research. It will also provide an opportunity for the students to network with foreign collaborators, which will be very beneficial to their long-term career development.
This project will enable the Lamont-Doherty scientists to quantify the rates of supply and removal of trace elements in the severely undersampled SPSG, the ocean's largest biogeographic province, characterized by a hyper-oligotrophic (low biological productivity) ecosystem and ultra-low dust fluxes. Evaluating the supply of trace elements from dust provides critical information about sources of essential micronutrients that influence the ecology and biogeochemistry of the SPSG. The award will cover the travel expenses for two people to participate in the cruise, shipping to and from the cruise, and instrument fees to analyze samples collected on the cruise. Comparing scavenging results from the SPSG with results from recent studies of other biogeographic providences, including the North Pacific Subtropical Gyre, the Subarctic North Pacific, the North Atlantic Subtropical Gyre and the Eastern Tropical South Pacific, will build toward the team's long-range goal of characterizing the intensity of trace element removal from the ocean in terms of environmental, ecological and biogeochemical characteristics of ocean biogeographic provinces. The deep water column of the SPSG is influenced by the hydrothermal plume emanating from the East Pacific Rise. Comparing SPSG results with those from regions lacking significant influence by hydrothermal plumes will also enable them to constrain the role of these plumes in defining the global distribution of trace elements in the deep ocean. This effort should provide rates of supply and removal of biologically essential micronutrients, and of other trace elements, in an end-member ocean regime that is not scheduled for sampling by a GEOTRACES ocean section, thus filling a gap in the global database for trace elements and isotopes under development by GEOTRACES. Results will be obtained using GEOTRACES-compliant methods, and made available through the GEOTRACES database for use by investigators in other fields.
