attribute NC_GLOBAL acquisition_description String Location: Cultures collected from Northeast Pacific Line P Transect 48.8167 N\n128.667 W\n \nMetal quotas  \n Cellular metal quotas were measured by inductively coupled plasma mass\nspectrometry (ICP-MS). Biomass from replicate 25 mL matrix cultures of P.\ntricornutum CCMP632, P. delicatissima UNC1205, and Thalassiosira UNC1203 were\npooled upon entering stationary phase and were centrifuged at 11,000 RPM\n(14,610 x g) for 40 minutes at 4\\u00b0C. The cell pellet was resuspended in ~1\nmL media and transferred to an acid-cleaned microcentrifuge tube. Cultures\nwere centrifuged again for 30 min at 14,100 RPM (13,336 x g) at 4\\u00b0C\nbefore the supernatant was discarded. The remaining cell pellet was acidified\nin 800 L of 5% nitric acid (Optima) containing 1 ppb indium for at least seven\ndays. Solids were removed by centrifugation. No attempt was made to remove\nextracellular metals by washing cells with additional metal chelators in order\nto minimize processing blanks. Quota determinations therefore include\ncontributions from both intracellular and extracellular pools. Process blank\ndigestions containing acid but no cells were performed in parallel. Digests\nwere diluted by a factor of 9 with 5% nitric acid 1 ppb indium solution before\nbeing analyzed in duplicate on a Thermo ICAP-Q plasma mass spectrometer\ncalibrated to a multi-element standard curve (Spex Certiprep) over a range of\n1 \\u2013 20 ppb. Samples were analyzed in KED mode after an 85s sample uptake\nwindow and element mass windows were scanned 3 times during measurements. The\n1 ppb indium internal standard was used to correct for variation in sample\ndelivery and plasma suppression between samples. Process blanks were\nsubtracted from measured concentrations. Phosphorus concentrations were also\nmeasured by ICP-MS simultaneously and were calibrated to a standard curve\nranging from 100 \\u2013 3,200 ppb using a 1 ppm certified P stock (Alfa Aesar\nSpecpure). The seawater media base used for all growth experiments was\nsimilarly analyzed via ICP-MS using a 1:10 dilution of media base into 5%\nnitric acid 1 ppb indium and analyzed as above to determine background media\nconcentrations of total Zn and Co (0.9 nmol L-1 and 0.1 nmol L-1,\nrespectively).\n \nMissing data identifiers in this dataset include:  \n * \"nd\" indicating no data  \n * Below Detection  \n * \"contam\" indicating the sample was contaminated\n \nIsolation sources and locations  \n * Pseudonitzschia delicatissima UNC1205 and Thalassiosira UNC1203 were\nisolated from  \n station P8 of the Line P transect, 48.817\\uf0b0N 128.666\\uf0b0W  \n * Phaeodactylum tricornutum CCMP632 was ordered from Bigelow, the strains\noriginal  \n location of isolation was 54\\uf0b0N 4\\uf0b0W  \n * Thalassiosira pseudonana CCMP1335 was also from Bigelow, original location\nof  \n isolation was 40.756\\u00b0 N 72.82\\u00b0 W

attribute NC_GLOBAL projects_0_acronym String PMT Cobalt and Metalloenzymes
attribute NC_GLOBAL projects_0_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.
