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 5L 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 until the end of the\ncruise and then at room temperature once shipped to the participating\nlaboratories analysis.\n \nAnalytical methods for dissolved radionuclides:  \nLDEO:  \n In the on-shore laboratory, seawater samples were weighed to determine\nsample size, taking into account the weight of the cubitainer and of the acid\nadded at sea. Then weighed aliquots of the artificial isotope yield monitors\n229Th (20 pg) and 233Pa (0.5 pg) and 15 mg dissolved Fe were added to each\nsample. After allowing 1 day for spike equilibration, the pH of each sample\nwas raised to 8.3-8.7 by adding ~12 mL of concentrated NH4OH (Fisher\nScientific OPTIMA grade) which caused iron (oxy)hydroxide precipitates to\nform. Each sample cubitainer was fitted with a nozzle cap, inverted, and the\nFe precipitate was allowed to settle for 2 days. After 2 days, the nozzle caps\nwere opened and the pH~8.3-8.7 water was slowly drained, leaving only the iron\noxyhydroxide precipitate and 250-500mL of water. The Fe precipitate was\ntransferred to centrifuge tubes for centrifugation and rinsing with Milli-Q\nH2O (>18 M\\u03a9) to remove the major seawater ions. The precipitate was then\ndissolved in 16 M HNO3 (Fisher Scientific OPTIMA grade) and transferred to a\nTeflon beaker for a high-temperature (180-200\\u00b0C) digestion with HClO4 and\nHF (Fisher Scientific OPTIMA grade) on a hotplate in a HEPA-filtered laminar\nflow hood. After total dissolution of the sample, another precipitation of\niron (oxy)hydroxide followed and the precipitate was washed with Mill-Q H2O,\ncentrifuged, and dissolved in 12 M HCl for a series of anion-exchange\nchromatography using 6 mL polypropylene columns each containing a 1 mL bed of\nBio-rad resin (AG1-X8, 100-200 mesh size) and a 45 \\u03bcm porous polyethylene\nfrit (Anderson et al. 2012). The final column elutions were dried down at\n180\\u00b0C in the presence of 2 drops of HClO4 and taken up in approximately 1\nmL of 0.16 M HNO3/0.026 M HF 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 mode,\nwhile the 232Th signals were large enough that they were measured in Analog\nmode. Two solutions of SRM129, a natural U standard, were run multiple times\nthroughout each run. One solution was in a concentration range where 238U and\n235U were both measured in counting mode, allowing us to determine the mass\nbias/amu (typical values varied from -0.01/amu to 0.03/amu). In the other,\nmore concentrated solution, 238U was measured in Analog mode and 235U was\nmeasured 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 NBP1702\nsamples, with the exception of two batches (30 samples). It was discovered\nthat the 233Pa spike added to these batches also contained ~0.4fg of 231Pa.\nThe samples which had this contaminated spike added were blank corrected for\n231Pa using the average 231Pa values in the two procedural blanks run in each\nof those two batches. The average procedural blanks (not including two batches\nwith high 231Pa in the 233Pa spike) for 232Th, 230Th, and 231Pa were 3.2 pg,\n0.25 fg, and 0.01 fg respectively.\n \nDerived Parameters:  \n Th_230_D_XS_CONC_BOTTLE \\- The dissolved excess Th-230 concentration refers\nto the 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 and xs231Pa is small.\nTherefore, even for a sample where the 232Th, used to make the correction, is\nflagged as bad, the error contributed in calculating xs230Th nd xs231Pa is\nsmall, so they are flagged as questionable (2).\\u00a0See the Processing\nDescription for complete\\u00a0quality flag definitions.

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:\nScientists established more than 30 years ago that the climate-related variability of carbon dioxide levels in the atmosphere over Earth's ice-age cycles was regulated by the ocean. Hypotheses to explain how the ocean regulates atmospheric carbon dioxide have long been debated, but they have proven to be difficult to test. Work proposed here will test one leading hypothesis, specifically that the ocean experienced greater density stratification during the ice ages. That is, with greater stratification during the ice ages and slower replacement of deep water by cold dense water formed near the poles, the deep ocean would have held more carbon dioxide, which is produced by biological respiration of the organic carbon that constantly rains to the abyss in the form of dead organisms and organic debris that sink from the sunlit surface ocean. To test this hypothesis, the degree of ocean stratification during the last ice age and the rate of deep-water replacement will be constrained by comparing the radiocarbon ages of organisms that grew in the surface ocean and at the sea floor within a critical region around Antarctica, where most of the replacement of deep waters occurs. Completing this work will contribute toward improved models of future climate change. Climate scientists rely on models to estimate the amount of fossil fuel carbon dioxide that will be absorbed by the ocean in the future. Currently the ocean absorbs about 25% of the carbon dioxide produced by burning fossil fuels. Most of this carbon is absorbed in the Southern Ocean (the region around Antarctica). How this will change in the future is poorly known. Models have difficulty representing physical conditions in the Southern Ocean accurately, thereby adding substantial uncertainty to projections of future ocean uptake of carbon dioxide. Results of the proposed study will provide a benchmark to test the ability of models to simulate ocean processes under climate conditions distinctly different from those that occur today, ultimately leading to improvement of the models and to more reliable projections of future absorption of carbon dioxide by the ocean.\nThe proposed work will add a research component to an existing scientific expedition to the Southern Ocean, in the region between the Ross Sea and New Zealand, that will collect sediment cores at three to five locations down the northern flank of the Pacific-Antarctic Ridge at approximately 170°W. The goal is to collect sediments at each location deposited since early in the peak of the last ice age. This region is unusual in the Southern Ocean in that sediments deposited during the last ice age contain foraminifera, tiny organisms with calcium carbonate shells, in much greater abundance than in other regions of the Southern Ocean. Foraminifera are widely used as an archive of several geochemical tracers of past ocean conditions. In the proposed work the radiocarbon age of foraminifera that inhabited the surface ocean will be compared with the age of contemporary specimens that grew on the seabed. The difference in age between surface and deep-swelling organisms will be used to discriminate between two proposed mechanisms of deep water renewal during the ice age: formation in coastal polynyas around the edge of Antarctica, much as occurs today, versus formation by open-ocean convection in deep-water regions far from the continent. If the latter mechanism prevails, then it is expected that surface and deep-dwelling foraminifera will exhibit similar radiocarbon ages. In the case of dominance of deep-water formation in coastal polynyas, one expects to find very different radiocarbon ages in the two populations of foraminifera. In the extreme case of greater ocean stratification during the last ice age, one even expects the surface dwellers to appear to be older than contemporary bottom dwellers because the targeted core sites lie directly under the region where the oldest deep waters return to the surface following their long circuitous transit through the deep ocean. The primary objective of the proposed work is to reconstruct the water mass age structure of the Southern Ocean during the last ice age, which, in turn, is a primary factor that controls the amount of carbon dioxide stored in the deep sea. In addition, the presence of foraminifera in the cores to be recovered provides a valuable resource for many other paleoceanographic applications, such as: 1) the application of nitrogen isotopes to constrain the level of nutrient utilization in the Southern Ocean and, thus, the efficiency of the ocean?s biological pump, 2) the application of neodymium isotopes to constrain the transport history of deep water masses, 3) the application of boron isotopes and boron/calcium ratios to constrain the pH and inorganic carbon system parameters of ice-age seawater, and 4) the exploitation of metal/calcium ratios in foraminifera to reconstruct the temperature (Mg/Ca) and nutrient content (Cd/Ca) of deep waters during the last ice age at a location near their source near Antarctica.\nNote: Project Acronym \"SNOWBIRDS\" = Silicon and Nitrogen Observed in the Water column Biologic Isotope Records During Sedimentation
