attribute NC_GLOBAL acquisition_description String North and equatorial Pacific seawater samples were collected on the GP15\nexpedition as part of the U.S. GEOTRACES program (RR1804 and RR1805, September\nto November 2018). Dissolved water samples were collected along a transect\nthat mostly followed the 152W meridian from 76N to 20S, traveling from the\nGulf of Alaska to Hawaii (Leg 1), and on to Tahiti, French Polynesia (Leg 2).\nSampling locations included 20 deep full-depth stations with a bottom depth of\nover 4000 m, 5 shallow/coastal full-depth stations, and 10 surface stations\nwhere only the surface 1000 m was sampled.\n \nDissolved seawater samples were collected using a 24-bottle trace metal clean\nrosette equipped with 12 L Go-Flo bottles (General Oceanics), a titanium\nframe, and a Kevlar cable, as described in (Cutter and Bruland 2012). Surface\nwater samples were collected from a trace metal clean towfish and pump while\narriving at each station. Seawater from the Go-Flo bottles was subsampled in a\ntrace metal clean van under positive pressure. Dissolved Co subsamples were\nfiltered using a 0.2 um Acropack (Pall) and stored until analysis at 4 degrees\nC in a 60 mL LDPE bottle that had been soaked for ~1 week in Citranox, an\nacidic detergent, rinsed with Milli-Q water (Millipore), soaked for ~2 weeks\nin 10% trace metal grade HCl, and rinsed with lightly acidic Milli-Q water\n(<0.1% HCl). All Co values were analyzed at sea, but replicates of all samples\nwere taken for future dCo analysis in the laboratory. Preserved samples were\nfilled entirely with no remaining headspace, stored with one oxygen-absorbing\nsatchel (Mitsubishi Gas Chemical, model RP-3K) per 60 mL water sample, vacuum-\nsealed in plastic bags, and stored at 4 degrees C.\n \nDissolved cobalt was determined by cathodic stripping voltammetry (CSV) as\noriginally described by (Saito and Moffett 2001) and modified by (Saito et al.\n2010; Hawco et al. 2016). Measurement occurred shipboard within a trace metal\nclean plastic \\\"bubble\\\" within one week of sample collection using the\nMetrohm 663 VA and uAutolabIII systems equipped with a hanging mercury drop\nworking electrode. For total dissolved Co (dCo) analysis, 0.2 um filtered\nwater samples were UV-irradiated in acid-washed quartz tubes for one hour\nusing a water-cooled UV irradiation system (Metrohm 705 UV Digestor) to\ndestroy natural ligand-bound Co complexes. For labile dissolved Co analysis\n(L-dCo), no UV-irradiation was performed. Then, 11 mL of sample seawater was\naliquoted into 15 mL acid-washed polypropylene vials, and 33 uL of 0.1 M\ndimethyglyoxime (DMG, Sigma Aldrich) and 130 uL of 0.5 M\nN-(2-hydroxyethyl)piperazine-N-(3-propanesulfonic acid) (EPPS, Sigma Aldrich)\nbuffer was added. The samples were then processed on an autosampler (Metrohm\n858 Sample Processor), which added 8.5 mL of the sample solution and 1.5 mL of\na 1.5 M NaNO\\u2082 reagent (Merck) to a Teflon cup for electrochemical\nanalysis. The mercury electrode performed a fast linear sweep from -1.4 V to\n-0.6 V at a rate of 5 V s\\u207b\\u00b9, which reduced the Co bound in the\nCo(DMG)\\u2082 complex from Co(II) to Co(0) and produced a Co reduction peak at\n-1.15 V (Saito and Moffett 2001) with a height linearly proportional to the\namount of dCo present in the sample. A standard curve was created with 4\nadditions of 25 pM CoCl\\u2082 to each sample, and a linear regression of the\naddition standard curve allowed for the calculation of the initial amount of\nCo present in the sample, assuming all available Co binds to the DMG ligand.\nReagent purification protocols and standard addition calculations are outlined\nin more detail in (Saito and Moffett 2001). Triplicate technical replicates\nwere run on every sample to determine the precision of the method, and\nduplicate depths from different rosette casts were run when available.

attribute NC_GLOBAL projects_0_description String A 60-day research cruise took place in 2018 along a transect form Alaska to Tahiti at 152° W. A description of the project titled \"Collaborative Research: Management and implementation of the US GEOTRACES Pacific Meridional Transect\", funded by NSF, is below. Further project information is available on the US GEOTRACES website and on the cruise blog. A detailed cruise report is also available as a PDF.\nDescription from NSF award abstract:\nGEOTRACES is a global effort in the field of Chemical Oceanography in which the United States plays a major role. The goal of the GEOTRACES program is to understand the distributions of many elements and their isotopes in the ocean. Until quite recently, these elements could not be measured at a global scale. Understanding the distributions of these elements and isotopes will increase the understanding of processes that shape their distributions and also the processes that depend on these elements. For example, many \"trace elements\" (elements that are present in very low amounts) are also important for life, and their presence or absence can play a vital role in the population of marine ecosystems. This project will launch the next major U.S. GEOTRACES expedition in the Pacific Ocean between Alaska and Tahiti. The award made here would support all of the major infrastructure for this expedition, including the research vessel, the sampling equipment, and some of the core oceanographic measurements. This project will also support the personnel needed to lead the expedition and collect the samples.\nThis project would support the essential sampling operations and infrastructure for the U.S. GEOTRACES Pacific Meridional Transect along 152° W to support a large variety of individual science projects on trace element and isotope (TEI) biogeochemistry that will follow. Thus, the major objectives of this management proposal are: (1) plan and coordinate a 60 day research cruise in 2018; (2) obtain representative samples for a wide variety of TEIs using a conventional CTD/rosette, GEOTRACES Trace Element Sampling Systems, and in situ pumps; (3) acquire conventional CTD hydrographic data along with discrete samples for salinity, dissolved oxygen, algal pigments, 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 data to the GEOTRACES Data Assembly Centre (via the US BCO-DMO data center); and (6) coordinate all cruise communications between investigators, including preparation of a hydrographic report/publication. This project would also provide baseline measurements of TEIs in the Clarion-Clipperton fracture zone (~7.5°N-17°N, ~155°W-115°W) where large-scale deep sea mining is planned. Environmental impact assessments are underway in partnership with the mining industry, but the effect of mining activities on TEIs in the water column is one that could be uniquely assessed by the GEOTRACES community. In support of efforts to communicate the science to a wide audience the investigators will recruit an early career freelance science journalist with interests in marine science and oceanography to participate on the cruise and do public outreach, photography and/or videography, and social media from the ship, as well as to submit articles about the research to national media. The project would also support several graduate students.

attribute NC_GLOBAL projects_1_acronym String PMT Cobalt and Metalloenzymes
attribute NC_GLOBAL projects_1_description String NSF abstract:\nCobalt is important for many forms of marine life, yet it is one of the scarcest nutrients in the sea. Cobalt's oceanic abundance and distribution, along with other scarce nutrients, can influence the growth of microscopic plants (phytoplankton). This in turn can influence carbon cycles in the ocean and atmosphere. Therefore, knowledge of the controls on cobalt's abundance and chemical forms in seawater is a valuable component of our ability to understand the ocean's influence on global carbon cycling. Within phytoplankton and other marine microbes, metals such as cobalt, iron, nickel, and copper are used as critical components of enzymes responsible for key cellular reactions. Since these enzymes require metals to work, they are named metalloenzymes. Participating in a Pacific Ocean cruise from Alaska to Tahiti, this project will study the oceanic distributions of dissolved cobalt and the cellular content of a group of metalloenzymes known to influence biogeochemical cycles. The project will provide scientific impact by creating new knowledge about oceanic micronutrients in regions of economic interest with regard to fisheries and deep-sea mining. Measurement of proteins in the North Pacific will provide data of broad biological and chemical interest and will be made available through a new NSF-funded \"EarthCube Ocean Protein Portal\" data base. Educational impact will stem from participation of a graduate student and two young technicians, as well as the PI's development of a high school chemistry curriculum for use in two local high schools, thus allowing teachers to include real oceanic and environmental data at their first introduction to chemistry.\nCobalt has a complex biogeochemical cycle. Both its inorganic and organic forms are used by biology in the upper ocean and it is removed from solution by being scavenged in the intermediate and deep ocean. This scavenging removal results in cobalt having the smallest oceanic inventory of any biologically utilized element. Recent studies, however, have found that large dissolved cobalt plumes occur in major oxygen minimum zones due to a combination of less scavenging and additions from sedimentary and remineralization fluxes. The GP15 US GEOTRACES Pacific Meridional Transect (PMT) provides an opportunity to examine the influence of oxygen depletion on cobalt chemistry. Moreover, the study of the protein component of microbial communities using new proteomic techniques will provide evidence of how different major microorganisms respond to the chemical environment (e.g. through transporter production for specific nutrients and micronutrients) as well as the biochemical basis for metal requirements related to the use of specific metalloenzymes. Specifically, the PMT provides an opportunity to confirm that the Pacific oxygen minimum zones contain a large amount of cobalt and to test the hypotheses that simultaneous zinc scarcity could induce wide-scale biochemical substitution of cobalt for zinc in the North Pacific Ocean.
