attribute	NC_GLOBAL	acquisition_description	String	Sample collection and filtering: Water column samples were collected by the\nU.S. GEOTRACES sampling team from 24 modified 12-L Teflon-coated GO-FLO\nsamplers (General Oceanics) deployed on the GEOTRACES clean CTD rosette system\n(Cutter and Bruland 2012). The U.S. GEOTRACES sampling team filtered the\nsamples through 0.2 \\u00b5m Supor Acropak filter cartridges (Pall) inside the\nU.S. GEOTRACES clean-air laboratory van. Near-surface samples (~2 m depth)\nwere collected underway either on approach or leaving each station using the\nKen Bruland lab towfish, \\u201cGeoFish\\u201d, deployed to collect surface\nsamples from outside the wake of the ship. Seawater from the GeoFish was\npumped directly into the Bruland lab clean air laboratory van and filtered\nthrough 0.2 \\u00b5m Supor Acropak filter cartridges.\n \nFiltered seawater samples for iron speciation (organic complexation) were\ncollected in 500 mL acid-cleaned Nalgene narrow-mouth fluorinated high-density\npolyethylene (FPE) bottles that had been filled with Milli-Q for at least two\nweeks after acid cleaning and rinsed three times with filtered seawater prior\nto sample collection (Buck et al. 2012). All filtered seawater samples for\ndissolved iron speciation were frozen at -20 \\u00baC shipboard by the sampling\nteam and shipped to the University of South Florida for laboratory-based\nanalyses post cruise.\n \nDissolved iron speciation (organic complexation) analyses: Dissolved iron\nspeciation (organic complexation) was analyzed using competitive ligand\nexchange- adsorptive cathodic stripping voltammetry (CLE-AdCSV) with\nsalicylaldoxime as the added competing ligand (Buck et al. 2015), modified\nfrom the original Rue and Bruland (1995) method. A borate-ammonium buffer was\nadded to all vials, for a final pH of 8.2 (NBS scale; Buck et al. 2007, 2012).\nDissolved iron additions of 0 to 10 nM were used in the titrations, for a\ntotal of at least 15 points in each titration. These dissolved iron additions\nwere chosen to match those of the U.S. GEOTRACES North Atlantic dataset and\ninclude additional datapoints within this range to allow higher resolution\ndata within titrations (Buck et al. 2016). Deposition times of 90 to 600 s\nwere applied to the analyses, with typically longer deposition times for\ndeeper water column samples. CLE-AdCSV analyses were performed on\nBioanalytical Systems (BASi) Controlled Growth Mercury Electrodes (static\nmercury drop setting, size 14) with Epsilon e2 (BASi) electrochemical\nanalyzers. There are no reference samples available for iron speciation\nmeasurements of iron in seawater, though this method has been shown to compare\nwell with other labs and techniques in GEOTRACES intercalibration exercises\n(Buck et al. 2012, 2016).\n \nFLAG:\\u00a0The standard Ocean Data View qualifying flags were used (reference\nall flags\nat\\u00a0[https://www.bodc.ac.uk/data/codes_and_formats/odv_format/](\\\\\"https://www.bodc.ac.uk/data/codes_and_formats/odv_format/\\\\\")):\n \n1: Good Value: Good quality data value that is not part of any identified\nmalfunction and has been verified as consistent with real phenomena during the\nquality control process. [Used when data were shown to be reproducible]\n \n2: Probably Good Value: Data value that is probably consistent with real\nphenomena but this is unconfirmed or data value forming part of a malfunction\nthat is considered too small to affect the overall quality of the data object\nof which it is a part.

attribute	NC_GLOBAL	instruments_4_description	String	Bioanalytical Systems (BASi) Mercury drop electrodes are generated by the BASi Controlled Growth Mercury Electrode (CGME) in three modes:\n\n DME (Dropping Mercury Electrode) - mercury is allowed to flow freely from the reservoir down the capillary and so the growth of the mercury drop and its lifetime is controlled by gravity. (The optional 100 um capillary is recommended for this mode.)\n\n SMDE (Static Mercury Drop Electrode) - the drop size is determined by the length of time for which the fast-response capillary valve is opened, and the drop is dislodged by a drop knocker. The dispense/knock timing is microprocessor-controlled and is typically coordinated with the potential pulse or square-wave waveform. This mode can also used to generate the Hanging Mercury Drop Electrode required for stripping experiments.\n\n CGME (Controlled Growth Mercury Electrode) - the mercury drop is grown by a series of pulses that open the capillary valve. The number of pulses, their duration, and their frequency can be varied by PC control, providing great flexibility in both the drop size and its rate of growth. This CGME mode can be used for both polarographic and stripping experiments.\n\nhttp://www.basinc.com/products/ec/cgme.php

attribute	NC_GLOBAL	projects_0_description	String	From the NSF Award Abstract\nThe mission of the International GEOTRACES Program (www.geotraces.org), of which the U.S. chemical oceanography research community is a founding member, is \"to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions\" (GEOTRACES Science Plan, 2006). In the United States, ocean chemists are currently in the process of organizing a zonal transect in the eastern tropical South Pacific (ETSP) from Peru to Tahiti as the second cruise of the U.S.GEOTRACES Program. This Pacific section includes a large area characterized by high rates of primary production and particle export in the eastern boundary associated with the Peru Upwelling, a large oxygen minimum zone that is a major global sink for fixed nitrogen, and a large hydrothermal plume arising from the East Pacific Rise. This particular section was selected as a result of open planning workshops in 2007 and 2008, with a final recommendation made by the U.S.GEOTRACES Steering Committee in 2009. It is the first part of a two-stage plan that will include a meridional section of the Pacific from Tahiti to Alaska as a subsequent expedition.\nThis award provides funding for management of the U.S.GEOTRACES Pacific campaign to a team of scientists from the University of Southern California, Old Dominion University, and the Woods Hole Oceanographic Institution. The three co-leaders will provide mission leadership, essential support services, and management structure for acquiring the trace elements and isotopes samples listed as core parameters in the International GEOTRACES Science Plan, plus hydrographic and nutrient data needed by participating investigators. With this support from NSF, the management team will (1) plan and coordinate the 52-day Pacific research cruise described above; (2) obtain representative samples for a wide variety of trace metals of interest using conventional CTD/rosette and GEOTRACES Sampling Systems; (3) acquire conventional JGOFS/WOCE-quality hydrographic data (CTD, transmissometer, fluorometer, oxygen sensor, etc) along with discrete samples for salinity, dissolved oxygen (to 1 uM detection limits), plant pigments, redox tracers such as ammonium and nitrite, and dissolved nutrients at micro- and nanomolar levels; (4) ensure that proper QA/QC protocols are followed and reported, as well as fulfilling all GEOTRACES Intercalibration protocols; (5) prepare and deliver all hydrographic-type data to the GEOTRACES Data Center (and US data centers); and (6) coordinate cruise communications between all participating investigators, including preparation of a hydrographic report/publication.\nBroader Impacts: The project is part of an international collaborative program that has forged strong partnerships in the intercalibration and implementation phases that are unprecedented in chemical oceanography. The science product of these collective missions will enhance our ability to understand how to interpret the chemical composition of the ocean, and interpret how climate change will affect ocean chemistry. Partnerships include contributions to the infrastructure of developing nations with overlapping interests in the study area, in this case Peru. There is a strong educational component to the program, with many Ph.D. students carrying out thesis research within the program.\nFigure 1. The 2013 GEOTRACES EPZT Cruise Track.

attribute	NC_GLOBAL	projects_1_description	String	Description from NSF award abstract:\nDissolved iron (Fe), copper (Cu), and cobalt (Co) are essential elements for phytoplankton growth which in turn influences the marine carbon cycle; however, despite this important role, the cycling, distribution, and bioavailability of these bioactive elements remains poorly understood. For example, strong organic ligands influence bioavailability and solubility, but it is unclear how interactions change throughout the water column under variable conditions. Recognizing a need for this data, researchers from the Bermuda Institute of Ocean Sciences, Woods Hole Oceanographic Institution, and Scripps Institute of Oceanography will measure the organic complexation of dissolved Fe, Cu, and Co as well as total dissolved Co concentrations during the 2013 GEOTRACES cruise which will transect the coastal upwelling zone off Peru, an intense oxygen minimum zone, the East Pacific Rise hydrothermal plume, and the oligotrophic waters near Tahiti. This study will result in a significant dataset on the speciation of these bioactive elements throughout the water column which will help assess the relationships between dissolved Fe, Cu, and Co distributions and ligand concentration gradients and will likely reveal large chemical gradients over this dynamic oceanographic region. As regards dissolved Co concentrations, these measurements should provide new insights on the marine biogeochemistry of the element, especially in relation to oxygen minimum zones and hydrothermal plumes.

Sample collection and filtering: Water column samples were collected by the\nU.S. GEOTRACES sampling team from 24 modified 12-L Teflon-coated GO-FLO\nsamplers (General Oceanics) deployed on the GEOTRACES clean CTD rosette system\n(Cutter and Bruland 2012). The U.S. GEOTRACES sampling team filtered the\nsamples through 0.2 \\u00b5m Supor Acropak filter cartridges (Pall) inside the\nU.S. GEOTRACES clean-air laboratory van. Near-surface samples (~2 m depth)\nwere collected underway either on approach or leaving each station using the\nKen Bruland lab towfish, \\u201cGeoFish\\u201d, deployed to collect surface\nsamples from outside the wake of the ship. Seawater from the GeoFish was\npumped directly into the Bruland lab clean air laboratory van and filtered\nthrough 0.2 \\u00b5m Supor Acropak filter cartridges.\n \nFiltered seawater samples for iron speciation (organic complexation) were\ncollected in 500 mL acid-cleaned Nalgene narrow-mouth fluorinated high-density\npolyethylene (FPE) bottles that had been filled with Milli-Q for at least two\nweeks after acid cleaning and rinsed three times with filtered seawater prior\nto sample collection (Buck et al. 2012). All filtered seawater samples for\ndissolved iron speciation were frozen at -20 \\u00baC shipboard by the sampling\nteam and shipped to the University of South Florida for laboratory-based\nanalyses post cruise.\n \nDissolved iron speciation (organic complexation) analyses: Dissolved iron\nspeciation (organic complexation) was analyzed using competitive ligand\nexchange- adsorptive cathodic stripping voltammetry (CLE-AdCSV) with\nsalicylaldoxime as the added competing ligand (Buck et al. 2015), modified\nfrom the original Rue and Bruland (1995) method. A borate-ammonium buffer was\nadded to all vials, for a final pH of 8.2 (NBS scale; Buck et al. 2007, 2012).\nDissolved iron additions of 0 to 10 nM were used in the titrations, for a\ntotal of at least 15 points in each titration. These dissolved iron additions\nwere chosen to match those of the U.S. GEOTRACES North Atlantic dataset and\ninclude additional datapoints within this range to allow higher resolution\ndata within titrations (Buck et al. 2016). Deposition times of 90 to 600 s\nwere applied to the analyses, with typically longer deposition times for\ndeeper water column samples. CLE-AdCSV analyses were performed on\nBioanalytical Systems (BASi) Controlled Growth Mercury Electrodes (static\nmercury drop setting, size 14) with Epsilon e2 (BASi) electrochemical\nanalyzers. There are no reference samples available for iron speciation\nmeasurements of iron in seawater, though this method has been shown to compare\nwell with other labs and techniques in GEOTRACES intercalibration exercises\n(Buck et al. 2012, 2016).\n \nFLAG:\\u00a0The standard Ocean Data View qualifying flags were used (reference\nall flags\nat\\u00a0[https://www.bodc.ac.uk/data/codes_and_formats/odv_format/](\\\\\"https://www.bodc.ac.uk/data/codes_and_formats/odv_format/\\\\\")):\n \n1: Good Value: Good quality data value that is not part of any identified\nmalfunction and has been verified as consistent with real phenomena during the\nquality control process. [Used when data were shown to be reproducible]\n \n2: Probably Good Value: Data value that is probably consistent with real\nphenomena but this is unconfirmed or data value forming part of a malfunction\nthat is considered too small to affect the overall quality of the data object\nof which it is a part. [Used when the reported value reflects analysis of a\nsingle or unverified replicate]\n \n3: Probably Bad Value: Data value recognized as unusual during quality control\nthat forms part of a feature that is probably inconsistent with real\nphenomena. [Not used]\n \n4: Bad Value: An obviously erroneous data value. [Not used]\n \n5: Changed Value: Data value adjusted during quality control. [Not used]\n \n6: Value Below Detection Limit: The level of the measured phenomenon was too\nsmall to be quantified by the technique employed to measure it. The\naccompanying value is the detection limit for the technique or zero if that\nvalue is unknown. [We report \\u201cnot_detected\\u201d rather than zero or a\ndetection limit value for this case]\n \n7: Value in Excess: The level of the measured phenomenon was too large to be\nquantified by the technique employed to measure it. The accompanying value is\nthe measurement limit for the technique. [Not used]\n \n8: Interpolated Value: This value has been derived by interpolation from other\nvalues in the data object. [Not used]\n \n9: Missing Value: The data value is missing. Any accompanying value will be a\nmagic number representing absent data. [Not used]

The Bioanalytical Systems EC epsilon is a family of potentiostat/galvanostats for electrochemistry. The most basic epsilon instrument can be used for standard techniques, as well as chronopotentiometry for materials characterization (e.g., characterization of transition metal complexes by cyclic voltammetry and controlled potential electrolysis, or of biosensors by cyclic voltammetry and constant potential amperometry). Pulse, square wave, and stripping techniques can be added by a software upgrade, and a second channel can be added by a hardware upgrade.\nhttp://www.basinc.com/products/ec/epsilon/

String

Bioanalytical Systems (BASi) Mercury drop electrodes are generated by the BASi Controlled Growth Mercury Electrode (CGME) in three modes:\n\n DME (Dropping Mercury Electrode) - mercury is allowed to flow freely from the reservoir down the capillary and so the growth of the mercury drop and its lifetime is controlled by gravity. (The optional 100 um capillary is recommended for this mode.)\n\n SMDE (Static Mercury Drop Electrode) - the drop size is determined by the length of time for which the fast-response capillary valve is opened, and the drop is dislodged by a drop knocker. The dispense/knock timing is microprocessor-controlled and is typically coordinated with the potential pulse or square-wave waveform. This mode can also used to generate the Hanging Mercury Drop Electrode required for stripping experiments.\n\n CGME (Controlled Growth Mercury Electrode) - the mercury drop is grown by a series of pulses that open the capillary valve. The number of pulses, their duration, and their frequency can be varied by PC control, providing great flexibility in both the drop size and its rate of growth. This CGME mode can be used for both polarographic and stripping experiments.\n\nhttp://www.basinc.com/products/ec/cgme.php

From the NSF Award Abstract\nThe mission of the International GEOTRACES Program (www.geotraces.org), of which the U.S. chemical oceanography research community is a founding member, is \"to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions\" (GEOTRACES Science Plan, 2006). In the United States, ocean chemists are currently in the process of organizing a zonal transect in the eastern tropical South Pacific (ETSP) from Peru to Tahiti as the second cruise of the U.S.GEOTRACES Program. This Pacific section includes a large area characterized by high rates of primary production and particle export in the eastern boundary associated with the Peru Upwelling, a large oxygen minimum zone that is a major global sink for fixed nitrogen, and a large hydrothermal plume arising from the East Pacific Rise. This particular section was selected as a result of open planning workshops in 2007 and 2008, with a final recommendation made by the U.S.GEOTRACES Steering Committee in 2009. It is the first part of a two-stage plan that will include a meridional section of the Pacific from Tahiti to Alaska as a subsequent expedition.\nThis award provides funding for management of the U.S.GEOTRACES Pacific campaign to a team of scientists from the University of Southern California, Old Dominion University, and the Woods Hole Oceanographic Institution. The three co-leaders will provide mission leadership, essential support services, and management structure for acquiring the trace elements and isotopes samples listed as core parameters in the International GEOTRACES Science Plan, plus hydrographic and nutrient data needed by participating investigators. With this support from NSF, the management team will (1) plan and coordinate the 52-day Pacific research cruise described above; (2) obtain representative samples for a wide variety of trace metals of interest using conventional CTD/rosette and GEOTRACES Sampling Systems; (3) acquire conventional JGOFS/WOCE-quality hydrographic data (CTD, transmissometer, fluorometer, oxygen sensor, etc) along with discrete samples for salinity, dissolved oxygen (to 1 uM detection limits), plant pigments, redox tracers such as ammonium and nitrite, and dissolved nutrients at micro- and nanomolar levels; (4) ensure that proper QA/QC protocols are followed and reported, as well as fulfilling all GEOTRACES Intercalibration protocols; (5) prepare and deliver all hydrographic-type data to the GEOTRACES Data Center (and US data centers); and (6) coordinate cruise communications between all participating investigators, including preparation of a hydrographic report/publication.\nBroader Impacts: The project is part of an international collaborative program that has forged strong partnerships in the intercalibration and implementation phases that are unprecedented in chemical oceanography. The science product of these collective missions will enhance our ability to understand how to interpret the chemical composition of the ocean, and interpret how climate change will affect ocean chemistry. Partnerships include contributions to the infrastructure of developing nations with overlapping interests in the study area, in this case Peru. There is a strong educational component to the program, with many Ph.D. students carrying out thesis research within the program.\nFigure 1. The 2013 GEOTRACES EPZT Cruise Track.

Description from NSF award abstract:\nDissolved iron (Fe), copper (Cu), and cobalt (Co) are essential elements for phytoplankton growth which in turn influences the marine carbon cycle; however, despite this important role, the cycling, distribution, and bioavailability of these bioactive elements remains poorly understood. For example, strong organic ligands influence bioavailability and solubility, but it is unclear how interactions change throughout the water column under variable conditions. Recognizing a need for this data, researchers from the Bermuda Institute of Ocean Sciences, Woods Hole Oceanographic Institution, and Scripps Institute of Oceanography will measure the organic complexation of dissolved Fe, Cu, and Co as well as total dissolved Co concentrations during the 2013 GEOTRACES cruise which will transect the coastal upwelling zone off Peru, an intense oxygen minimum zone, the East Pacific Rise hydrothermal plume, and the oligotrophic waters near Tahiti. This study will result in a significant dataset on the speciation of these bioactive elements throughout the water column which will help assess the relationships between dissolved Fe, Cu, and Co distributions and ligand concentration gradients and will likely reveal large chemical gradients over this dynamic oceanographic region. As regards dissolved Co concentrations, these measurements should provide new insights on the marine biogeochemistry of the element, especially in relation to oxygen minimum zones and hydrothermal plumes.
