attribute NC_GLOBAL acquisition_description String Dissolved data:  \n Water samples were collected with a Sea-Bird Electronics CTD carousel fitted\nwith 24 12-liter PVC Niskin bottles.The carousel was lowered from the ship\nwith steel wire. Niskin bottles were equipped with nylon-coated closure\nsprings and Viton O-rings. After collection seawater was drained with Teflon-\nlined TygonTM tubing and filtered through Pall AcropakTM 500 filters on deck\n(gravity filtration, 0.8/0.45 \\u03bcm pore size) into Fisher I-Chem series 300\nLDPE cubitainers. Approximately 10L was collected per desired depth. Prior to\nthe cruise, the tubing, filters, and cubitainers were cleaned by immersion in\n1.2 M HCl (Fisher Scientific Trace Metal Grade) for 4-5 days. Once filtered,\nsamples were adjusted to a pH ~2 with ultra-clean 6 M HCl (Fisher Scientific\nOPTIMA grade), double-bagged, stored in pallet boxes on-deck until the end of\nthe cruise and then at room temperature once shipped to the participating\nlaboratories analysis.\n \nAnalytical methods for dissolved radionuclides:  \n In the on-shore laboratory, ~5L of seawater was transferred into a new acid-\ncleaned cubitainer, weighed to determine sample size, taking into account the\nweight of the cubitainer and of the acid added at sea. Then weighed aliquots\nof the artificial isotope yield monitors 229Th (20 pg) and 233Pa (0.5 pg) and\n15 mg dissolved Fe were added to each sample. After allowing 1 day for spike\nequilibration, the pH of each sample was raised to 8.3-8.7 by adding ~12 mL of\nconcentrated NH4OH (Fisher Scientific OPTIMA grade) which caused iron\n(oxy)hydroxide precipitates to form. Each sample cubitainer was fitted with a\nnozzle cap, inverted, and the Fe precipitate was allowed to settle for 2 days.\nAfter 2 days, the nozzle caps were opened and the pH~8.3-8.7 water was slowly\ndrained, leaving only the iron oxyhydroxide precipitate and 250-500mL of\nwater. The Fe precipitate was transferred to centrifuge tubes for\ncentrifugation and rinsing with Milli-Q H2O (>18 M\\u03a9) to remove the major\nseawater ions. The precipitate was then dissolved in 16 M HNO3 (Fisher\nScientific OPTIMA grade) and transferred to a Teflon beaker for a high-\ntemperature (180-200\\u00b0C) digestion with HClO4 and HF (Fisher Scientific\nOPTIMA grade) on a hotplate in a HEPA-filtered laminar flow hood. After total\ndissolution of the sample, another precipitation of iron (oxy)hydroxide\nfollowed and the precipitate was washed with Mill-Q H2O, centrifuged, and\ndissolved in 12 M HCl for a series of anion-exchange chromatography using 6 mL\npolypropylene columns each containing a 1 mL bed of Bio-rad resin (AG1-X8,\n100-200 mesh size) and a 45 \\u03bcm porous polyethylene frit (Anderson et al.\n2012). The final column elutions were dried down at 180\\u00b0C in the presence\nof 2 drops of HClO4 and taken up in approximately 1 mL of 0.16 M HNO3/0.026 M\nHF for mass spectrometric analysis.\n \nConcentrations of 232Th, 230Th, and 231Pa were calculated by isotope dilution,\nrelative to the calibrated tracers 229Th and 233Pa added at the beginning of\nsample processing. Analyses were carried out on a Thermo-Finnegan ELEMENT XR\nSingle Collector Magnetic Sector ICP-MS, equipped with a high-performance\nInterface pump (Jet Pump), and specially-designed sample (X) and skimmer (Jet)\ncones to ensure the highest possible sensitivity. All measurements were made\nin low-resolution mode (\\u2206m/M\\u2248300), peak jumping in Escan mode across\nthe central 5% of the flat-topped peaks. Measurements were made on a\nMasCom\\u2122 SEM; 229Th, 230Th,231Pa, and 233Pa were measured in Counting\nmode, while the 232Th signals were large enough that they were measured in\nAnalog mode. Two solutions of SRM129, a natural U standard, were run multiple\ntimes throughout each run. One solution was in a concentration range where\n238U and 235U were both measured in counting mode, allowing us to determine\nthe mass bias/amu (typical values varied from -0.01/amu to 0.03/amu). In the\nother, more concentrated solution, 238U was measured in Analog mode and 235U\nwas measured in Counting mode, yielding a measurement of the Analog/Counting\nCorrection Factor. These corrections assume that the mass bias and Analog\nCorrection Factor measured on U isotopes can be applied to Th and Pa isotope\nmeasurements. Each sample measurement was bracketed by measurement of an\naliquot of the run solution, used to correct for the instrumental background\ncount rates. To correct for tailing of 232Th into the minor Th and Pa\nisotopes, a series of 232Th standards were run at concentrations bracketing\nthe expected 232Th concentrations in the samples. The analysis routine for\nthese standards was identical to the analysis routine for samples, so we could\nsee the changing beam intensities at the minor masses as we increased the\nconcentration of the 232Th standards. The 232Th count rates in our Pa\nfractions are quite small, reflecting mainly reagent blanks, compared to the\n232Th signal intensity in the Th fraction. The regressions of 230Th, 231Pa,\nand 233Pa signals as a function of the 232Th signal in the standards was used\nto correct for tailing of 232Th in samples.\n \nWater samples were analyzed in batches of 15. Procedural blanks were\ndetermined by processing two 4-5 L of Milli-Q water in an acid-cleaned\ncubitainer acidified to pH ~2 with 6 M HCl as a sample in each batch. An\naliquot of two intercalibrated working standard solutions of 232Th, 230Th and\n231Pa, SW STD 2010-1 referred to by Anderson et al. (2012) and SW STD 2015-1\nwhich has lower 232Th activity (more similar to Pacific seawater conditions),\nwere also processed like a sample in each batch. Samples were corrected using\nthe pooled average of all procedural blanks run during processing of SO245\nsamples. The average procedural blanks for 232Th, 230Th, and 231Pa were about\n7 pg, 0.5 fg, and 0.03 fg respectively.\n \nDerived parameters:  \nTh_230_D_XS_CONC_BOTTLE \\- The dissolved excess Th-230 concentration refers to\nthe measured dissolved Th-230 corrected for a contribution of Th-230 due to\nthe partial dissolution of uranium-bearing minerals, or lithogenics. Thereby\nthe dissolved excess represents solely the fraction of Th-230 produced in the\nwater by decay of dissolved uranium-234. We estimate the lithogenic Th-230\nusing measuring dissolved Th-232 and a lithogenic Th-230/Th-232 ratio of\n4.0e-6 (atom ratio) as determined by Roy-Barman et al. (2002) and a conversion\nfactor to convert picomoles to micro-Becquerels.\n \nTh_230_D_XS_CONC_BOTTLE = Th_230_D_CONC_BOTTLE \\u2013 4.0e-6 *1.7473e5 *\nTh_232_D_CONC_BOTTLE\n \nPa_231_D_XS_CONC_BOTTLE \\- The dissolved excess Pa-231 concentration refers to\nthe measured dissolved Pa-231 corrected for a contribution of Pa-231 due to\nthe partial dissolution of uranium-bearing minerals, or lithogenics. Thereby\nthe dissolved excess represents solely the fraction of Pa-231 produced in the\nwater by decay of dissolved uranium-235. We estimate the lithogenic Pa-231\nusing measuring dissolved Th-232 and a lithogenic Pa-231/Th-232 ratio of\n8.8e-8 (atom ratio) which is derived from assuming an average upper\ncontinental crustal U/Th ratio (Taylor and McClennan, 1995) and secular\nequilibrium between Pa-231 and U-235 in the lithogenic material. An additional\nconversion factor is needed to convert picomoles to micro-Becquerels.\n \nPa_231_D_XS_CONC_BOTTLE = Pa_231_D_CONC_BOTTLE \\u2013 8.8e-8 * 4.0370e5 *\nTh_232_D_CONC_BOTTLE\n \nThe correction for dissolved 231Pa and 230Th derived from dissolution of\nlithogenic particles, when calculating xs230Th\\u00a0 and xs231Pa\\u00a0 is\nsmall. Therefore, even for a sample where the 232Th, used to make the\ncorrection, is flagged as bad, the error contributed in calculating\nxs230Th\\u00a0and xs231Pa is small, so they are flagged as questionable (2).\nSee the Processing Description for complete\\u00a0quality flag definitions.

attribute NC_GLOBAL projects_0_acronym String UltraPac Trace Elements
attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nWith 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.\nThis 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.
