attribute NC_GLOBAL acquisition_description String Single water samples for nitrate isotopic analyses were collected from acid-\ncleaned, Teflon-coated X-Niskin sampling bottles (OceanTest Equipment) of\n8-liter capacity deployed on an epoxy-coated rosette (Sea-Bird Electronics)\nrosette as described in Noble et al. (2012). Samples were collected into\ntriple-rinsed 60 mL HDPE bottles and stored frozen at -20 degrees C until\nanalysis. Isotopic analyses of NO3 were made with a Finnigan DELTA PLUS XP\nIRMS using the denitrifier method (Sigman et al., 2001; Casciotti et al.,\n2002; McIlvin and Casciotti, 2011). Both d15N-NO3 and d18O-NO3 analyses were\nmade in duplicate and data are reported as means +/- 1 standard deviation.

attribute NC_GLOBAL projects_0_acronym String CoFeMUG
attribute NC_GLOBAL projects_0_description String The geochemistries of dissolved cobalt (Co) and iron (Fe) in the oceanic water column share several characteristics such as extremely low concentrations, redox chemistry, low solubility,and utilization as micronutrients by marine microbes. Iron has been the subject of considerable research focus in recent years due to its role in limiting phytoplankton productivity in oceanic and coastal upwelling environments. Cobalt has been much less studied, but recent data show it may be important in influencing primary productivity or phytoplankton community composition in certain geographical areas.\nThe CoFeMUG project predated GEOTRACES, so while it is not formally recognized as a GEOTRACES section, it is considered a GEOTRACES-related project and the CoFeMUG data are GEOTRACES compliant.\nState-of-the-art geochemical and molecular biological techniques were used to address biogeochemical questions in the South Atlantic, and focus especially on the two trace metals, cobalt and iron. The 27-day cruise in November and December 2007 to the South Atlantic was designed to study cobalt and iron biogeochemistry and focus on four major hypotheses.\n(1) Large fluxes of labile cobalt are associated with upwelling systems even in Aeolian dominated environments.\n(2) Cobalt and phosphate show correlations in (and only in) surface waters due to micronutrient utilization and rapid remineralization. The slope of the correlation is dependent on the chemical speciation of cobalt.\n(3) The absence of Trichodesmium populations in the subtropical and tropical South Atlantic is caused by iron limitation.\n(4) Based on work from the California and Peru Upwelling regimes, primary productivity in the Benguela upwelling regime off of South West Africa may be iron limited or iron-cobalt colimited.\nA combination of geochemical and biological/molecular analyses were made across an oligotrophic-upwelling transition to examine how changing metal regimes affect the physiology and growth of the important primary producers Trichodesmium and Synechococcus.\nCoFeMUG project results are published in:\nNoble, Abigail E., Carl H.
