attribute NC_GLOBAL acquisition_description String Sampling:  \n Full depth and super station samples were collected from the ship's rosette.\nSamples were filtered through 0.8/0.45 um acropak500 filter cartridges into\ntriple-rinsed 60 mL HDPE bottles. Demi station samples were collected from the\nGEOTRACES Go-Flo rosette. Samples were filtered through 0.2 um acropak capsule\nfilters into triple-rinsed 60 mL HDPE bottles. Each sample was collected in\ntriplicate. Samples were frozen at -20 C immediately and stored frozen until\nanalysis.\n \nAnalysis:  \n Samples were analyzed for nitrate d15N and d18O using the denitrifier method\n(Sigman et al., 2001; Casciotti, et al., 2001, with technical updates\ndescribed by McIlvin and Casciotti, 2011). Nitrate isotope reference materials\nUSGS32, USGS34, and USGS35 were used to calibrate d18O and USGS32 and USGS34\nto calibrate d15N. Each sample was analyzed 2-6 times. Mean and standard\ndeviations are reported for each sample. All samples were analyzed on a\nDeltaPLUS XP isotope ratio mass spectrometer, with custom-built inlet\ndescribed in McIlvin and Casciotti, 2011.\n \nWhere possible (concentrations exceeded 2 uM), samples and standards were\nanalyzed in 20 nanomole aliquots. When NO3- concentrations were below 2 uM,\nsamples were injected in maximum volume (10 mL) and calibrated using\ninterpolations between standard curves of 5 and 20 nano moles NO3-. Some\nsamples contained nitrate concentrations lower than the typical analytical\nwindow (300 nM NO3-), but were analyzed nonetheless. Samples analyzed with\nconcentrations below 0.3 uM are were flagged as \\\"low concentration\\\". These\nsamples contained a subset with major ion peak areas (m/z 44) less than 1\nvolt-second, which are flagged at \\\"low area\\\". Two of these samples are\nflagged as having elevated d18O-NO3 values relative to their d15N-NO3 values.\nThe flagged samples should be treated with caution.\n \nThis version (16 March 2013) has not been thoroughly intercalibrated with data\nfrom the Sigman Lab. Currently, there exists no detachable d15N offset between\nthe datasets. However, Casciotti d18O data are approximately 0.6 permil higher\nthan Sigman d18O data.

attribute NC_GLOBAL projects_0_description String Much of this text appeared in an article published in OCB News, October 2008, by the OCB Project Office.\nThe first U.S. GEOTRACES Atlantic Section will be specifically centered around a sampling cruise to be carried out in the North Atlantic in 2010. Ed Boyle (MIT) and Bill Jenkins (WHOI) organized a three-day planning workshop that was held September 22-24, 2008 at the Woods Hole Oceanographic Institution. The main goal of the workshop, sponsored by the National Science Foundation and the U.S. GEOTRACES Scientific Steering Committee, was to design the implementation plan for the first U.S. GEOTRACES Atlantic Section. The primary cruise design motivation was to improve knowledge of the sources, sinks and internal cycling of Trace Elements and their Isotopes (TEIs) by studying their distributions along a section in the North Atlantic (Figure 1). The North Atlantic has the full suite of processes that affect TEIs, including strong meridional advection, boundary scavenging and source effects, aeolian deposition, and the salty Mediterranean Outflow. The North Atlantic is particularly important as it lies at the \"origin\" of the global Meridional Overturning Circulation.\nIt is well understood that many trace metals play important roles in biogeochemical processes and the carbon cycle, yet very little is known about their large-scale distributions and the regional scale processes that affect them. Recent advances in sampling and analytical techniques, along with advances in our understanding of their roles in enzymatic and catalytic processes in the open ocean provide a natural opportunity to make substantial advances in our understanding of these important elements. Moreover, we are motivated by the prospect of global change and the need to understand the present and future workings of the ocean's biogeochemistry. The GEOTRACES strategy is to measure a broad suite of TEIs to constrain the critical biogeochemical processes that influence their distributions. In addition to these \"exotic\" substances, more traditional properties, including macronutrients (at micromolar and nanomolar levels), CTD, bio-optical parameters, and carbon system characteristics will be measured. The cruise starts at Line W, a repeat hydrographic section southeast of Cape Cod, extends to Bermuda and subsequently through the North Atlantic oligotrophic subtropical gyre, then transects into the African coast in the northern limb of the coastal upwelling region. From there, the cruise goes northward into the Mediterranean outflow. The station locations shown on the map are for the \"fulldepth TEI\" stations, and constitute approximately half of the stations to be ultimately occupied.\nFigure 1. The proposed 2010 Atlantic GEOTRACES cruise track plotted on dissolved oxygen at 400 m depth. Data from the World Ocean Atlas (Levitus et al., 2005) were plotted using Ocean Data View (courtesy Reiner Schlitzer). [click on the image to view a larger version]\nHydrography, CTD and nutrient measurements will be supported by the Ocean Data Facility (J. Swift) at Scripps Institution of Oceanography and funded through NSF Facilities. They will be providing an additional CTD rosette system along with nephelometer and LADCP. A trace metal clean Go-Flo Rosette and winch will be provided by the group at Old Dominion University (G. Cutter) along with a towed underway pumping system.\nThe North Atlantic Transect cruise began in 2010 with KN199 leg 4 (station sampling) and leg 5 (underway sampling only) (Figure 2).\nKN199-04 Cruise Report (PDF)\nFigure 2. The red line shows the cruise track for the first leg of the US Geotraces North Atlantic Transect on the R/V Knorr in October 2010.  The rest of the stations (beginning with 13) will be completed in October-December 2011 on the R/V Knorr (courtesy of Bill Jenkins, Chief Scientist, GNAT first leg).
